Step 4: Remove the laptop’s backplate

Remove the laptop’s backplate using the small knife tool. Try to separate the backplate from the laptop by wedging the knife in between the small groove. After the knife has been wedged, attempt to slowly run the knife across the edges of the backplate until the backplate has been removed. Protect the laptop from scratches by placing a micro-fiber cloth in front of the knife.

Step 5: Remove the original RAM and SSD

This model of the LG Gram 17″ comes with 16 GB of Ram (8 GB Soldered, 8 GB Swappable). The laptop also comes with two-slots of SATA3 (SATA3 x4, SATA3 x2). In the faster SATA3 x4 slot, the laptop comes with a 256 GB SATA SSD.

Step 6: Add the new ram and SSD

Move the original 256 SATA SSD to the second SATA3 x2 slot (Right). Insert the new SSD and RAM module.

** The SATA3 NVME x4 Slot (Left) is faster and you should put your Samsung NVME in this slot for faster boot times. For this to work, the Windows Operating System must also be installed on the Samsung 970 EVO NVME drive.

Step 7: Check computer specs

Before reassembling the laptop, ensure that the laptop is detecting all of the parts. Check “System information” to ensure that the additional RAM is detected and run “Disk Management” to check for the new SSD.

You have now completed the LG Gram 17 Storage/Ram Upgrade Guide. If you want to migrate the operating system onto the 1 TB SSD, you can do a fresh install of Windows or use the Samsung SSD migration software.

*Note: if you clone your drive with SSD migration software. Your computer might not boot if it detects two drives with the Windows OS. You can test this by removing one of the drives, and booting from a single drive. If this is true, you can create a Windows ISO USB and boot from it to enter the “Windows Installer” mode. In the Windows Installer, you can wipe the unused drive.

  • Still works! I purchased PNY ddr4 32gb 2666mhz and Samsung SSD 970 evo plus. Runs great. I had to go online and search for formatting my old SSD and how to get the computer to recognize it but everything else followed your direction. Thanks!

  • Hi. Glad I found this blog. I bought Crucial P3 Plus 4TB PCIe M.2 2280 SSD 4th gen. After installing as a second drive, the computer wouldn’t start. Would start fine without it or with a 1 TB drive I had there before. Do you think a 2TB version of that same drive would work or do I need to go with a slower drive. Thanks. I have the older Gram from Costco, seems like the one you have on a video. Model: 17Z990-R.AAS7U1

      • I just recently returned a Crucial P3 Plus 500 GB PCIe M.2 2280 SSD 4th Gen. that would not work as either a second drive or in the original left side drive slot. I tried changing the boot order in BIOS, and nothing would work. The 2019 LG Gram 17″ would only boot with the original drive.

        I plan to install an AData Legend 840 PCIe Gen4 x4 M.2 2280 500 GB drive this weekend. I have verified with LG Technical support the motherboard supports the Gen4 4×4 drive.

        I’m keeping my fingers crossed that it works.

        • The other option is to keep the new SSD as the only drive and try to use a Windows iso install usb on the new ssd.

          Change the bios to the usb and install windows on the new drive

          • I could not remove the original drive screw at the time to try that option. I since have used a different, larger screw driver to remove the screw.

      • Thanks for a prompt reply. I will try that. I don’t want to go through a trouble of reinstalling windows and all the soft. I just need a larger second drive to work on my 4k family videos. External drives are too slow.

  • Is it possible to dual boot? I am wondering if I can install Linux distro on the second slot and dual boot from that instead of using it as extended storage for the windows oration in the first slot.

    • Yes, it is possible. I use dual boot that way on LG Gram 2020. You may need to disable safe boot in BIOS first, so Linux can boot.

  • Hi, I have the Lg Gram 2021 model 17z90pkaa75a8 16gb installed, crucial scanner keeps failing on me.
    Could someone tell me what ram I should get? 32? more? what speed etc.I cant seem to find any info online except here [ thank you ]

  • I have a 2020 17 inch, however the ram is soldered and am curious if anyone else has ran into this? I was looking specifically for a 2020 version so that I could eventually upgrade.

    It’s definitely not a 2021 version as it has a barrel ac power adapter and only one usb C port. The other weird thing is that the cpu appears to be 11th generation i7 and not 10th like I’d expect for a 2020 model.

    This might be some sort of transition between model years due to supply chain issues. Or maybe its a grey market or international version – bought it on craigslist so not really sure whats going on. Has anyone else ran into this?

  • Upgraded the 2020 14Z90N-V with Samsung 980 Evo 500gb (Non-Pro) and it runs a lot cooler (about 5c on an average) than the stock Hynix. Read speeds are more or less same (3100 Mbps) but the write speeds are a league ahead (2600 Mbps) SK Hynix would on an average throttle around 930 Mbps. Also, added an another 8GB 3200Mhz CL22 Crucial Ram stick. I was little skeptical to open it initially but after reading the comments got the confidence. Thanks for the guide and pics.

  • I realise that this is an old thread but this video helped me upgrade the ssd on my 2021 gram 17. So thanks for that!

    If anyone is curious I put in a 1tb Sabrent Rocket Plus, which works fine and I would expect all other PCIe 4 drives to work.

    Although it is only operating at PCIe 3 speeds, for some reason it seems the m.2 slot isn’t auto detecting the faster capability. Anyone else had success getting it to work?


  • Anybody who ever updated computers knows that RAM memory should only be installed in identical pairs, for fast dual channel memory operation.
    An 8GB + 32GB makes no sense whatsoever. Granted, you get a total of 40GB of RAM, but it will operate in the much slower single channel mode.
    Examples – 16Gb as 2 x 8GB, 32GB as 2 x 16GB, etc.
    LG screwed up by having RAM soldered unto the motherboard, since you can never match the exact brand of existing RAM. You can however get a working dual channel by installing the exact value as what you already have, in this case, another 8GB, for a dual channel 16GB – 2 x 8GB.
    Also, the Crucial RAM is low end crap, even worse than Hynix.
    I only use high end RAM, such as G.Skill or Corsair Hyper X.

    • Anyone who has ever worked on computers knows that time does not stand still and that things change. The 8GB + 32GB works just fine in this LG application. Best to keep the same speed on the Memory Modules though:
      DDR4 2666Mhz SODIMM (2019 LG Gram 17)
      DDR4 3200Mhz SODIMM (2020 LG Gram 17)

      This mixing might not work in another computer or even in an older LG.

      So Doruletz, don’t get your panties in a wad.
      But hey, if you only want to have 8GB + 8GB in your LG, then carry on my wayward friend…

      • https://www.makeuseof.com/tag/myths-misconceptions-about-ram/amp/

        “For example, if your first stick is 4GB, you can still add a new 8GB stick. Once you switch on dual-channel mode (also called flex mode), it will perform as two 4GB sticks running side by side in optimal performance. The remaining 4GB of the new stick will run in single-channel mode.”

        With the 32gb + 8gb setup, you get 8gb in dual channel and 24gb in single channel. The extra GBS of ram is especially great for those working with multiple Virtual Machines.

  • anyone knows how to install windows server on these so touchpad works?
    is there specific windows feature to add?
    there seems problem with i2c device driver as if redmond deliberately banned server installations on some laptops.

    • Also, I would like to thank you for creating this post. This is literally the only thing that shows up on google regarding LG gram upgrade instructions.

  • Thank you J and others posting updates,
    I was able to setup a Costco 2020 LG Gram 17″ version with a 2TB Samsung EVO Plus on the “left” slot, moved the original SSD to the “right” slot, all successfully. I wanted to add that the back panel of the laptop was kinda stuck, I had to slide the whole back panel to one side to be able to deattach it. Also, I recommend to install Win10 from USB, had to use MSCONFIG to remove the old Win10 install to prevent a Windows dual boot screen popping up. Finally, I recommend to applying some new adhesive to the rubber guards since removing them makes them slightly loose.

    • Please share the name/kind of adhesive you found works best for the feet. I noticed the same thing, but I didn’t know where to find some good adhesive.


  • Pleased to report the successful installation of
    a Team Elite 32 Gb DDR4 SO-DIMM 3200, C22TED432G3200C22-501 memory
    and an SK hynix Gold P31 1 TB SSD
    on a European 2020 i7-1065G7 LG Gram 17

    Cloning the OEM SSD to the new one with the https://www.macrium.com/sk-hynix tool was a breeze.

    • Unfortunately, just like Steve M did earlier, not only the presence of the SK hynix Gold P31 1 TB SSD did jeopardize the battery control software, but, in addition, after a few days of blazing speed, it has slowed down the Gram 17 to the point it was barely usable. After removing it and putting back the OEM Samsung SSD in the first slot, everything is back to normal.

  • I am planning to order 32GB Ram upgrade for my Costco 2020 yer LG Gram 17Z90N-R.AAS8U1 .
    Can some one confirm that this model accepts 40GB total.

    • Answering my own question: It works. Installed CT32G4SFD832A as per provided link to purchase.
      It is all good on my Costco 2020 yer LG Gram 17Z90N-R.AAS8U1, an upgrade to 40GB RAM works great. Also upgraded SSD, added 1TB as per this article recommendations.

      Jay, thanks for publishing this.

  • Thanks for publishing this; it gave me the reassurance I needed before pulling the trigger on a 32GB SODIMM (CT32G4SFD832A) for my LG Gram 17 (exact model 17Z90N-V.AA75A1)

    I can report it seems to work perfectly, and the BIOS reports system memory running at 3200MHz… though Windows 10 insisted on running chkdsk after I rebooted, so I’d recommend making sure you’ve done a full shutdown before installing.


      My LG Gram 17inch (Costco) (and un-modified hardware) is stuck on Windows Automatic Repairing screen since this morning.
      I’ve tried – all Windows Recovery options – Startup / Reset / Start Fresh/Back out Windows Updates, etc. Nothing succeeds.

      It seems that I have to install Windows using the USB port.
      So I created a USB boot flash drive using the Windows Media Creation Tool. The current issue is that the laptop won’t boot from that drive.
      On the BIOS, I’ve disabled Secure Boot Option (under Security). Any suggestions to help me proceed ahead.

      Very frustrated, the machine is just a few months old. I have not really used it beyond watching a couple of movies and general browsing every other day.

        • I do.
          When I select the USB drive in that menu, nothing happens. As if the laptop looks in to the USB drive and does not like the image for some reason.

          • If you have another Laptop or Desktop that supports m.2, you can plug the hard drive into that and wipe it using the disk manager.

      • Hmm.
        After plugging in the USB boot flash drive (Windows Media Creation Tool), did you go to BIOS and change the “Boot Order”? If not, change the “Boot Order” so that it boots from the flash drive first instead of the m.2 hard drive.
        Let me know if this works.

        • Yes changed the boot order to have the USB CD and USB HDD at the top.

          I think that there is some additional change needed in UEFI/CSM and other settings on the BIOS, based on what I see on the web. I’ve tried disabling UEFI, in that case the laptop just stops at the Boot Option (USB, NVMe…) etc menu.

          • I do not have another laptop with M2.
            My son has one but he is busy with his school stuff.

            There has to be a simple explanation to this one.
            1) I have changed the boot order
            2) The USB drive is brand new Samsung EVO USB3.0 flash drive
            … What should I check? …

          • You can also try reformatting your flash drive again with Windows Media Creation Tool and see if that works.

          • -So I recreated the USB Windows image using Media Creation tool. Tested the USB in another laptop. It worked fine, I got the expected Windows Setup screen on boot-up. I did not change any BIOS

            – In addition to the Boot order, I’ve made the following changes in the LG Gram BIOS:
            Main-> UEFI Boot – Change to Disable
            Main-> CSM Support – Yes
            Main-> UEFI Boot – change to Disable
            Main-> Legacy Boot – change to Enable
            Security-> Secure Boot Option – change to Disable

            I get to the screen which shows the boot devices:
            1) USB drive (recognizes that it is a Samsung drive)
            2) windows Boot Mgr
            3) NVME1

            When I manually select the USB Drive and click on it, NOTHING HAPPENS… Very puzzling..

          • The only other thing that I can think of is to remove your NVME and see if it boots into the USB.

            Also try resetting bios to default settings.

  • Very helpful detail on what was required to upgrade memory and add second NVMe drive. I replaced the factory 8G RAM with a HYPERX (HX432S20IB/32) 32GB DDR4-3200 stick. No issues so far with the memory upgrade. My NVMe upgrade however was not so perfect. I purchased a SK hynix Gold P31 (M.2 2280) 1TB and put it in the 2nd slot. Performance was amazing; however, after a few months of use I noticed that my battery status was not updating while using the computer. This was in both Windoze and Linux Mint, I traced it to the NVMe upgrade. Not sure how an NVMe SSD can interfere with ACPI function. I ordered a Samsung 970 EVO Plus to replace it since it seems to be work in this model based on the comments left here.

  • Hello Jay and other commenters,

    I got an LG Gram 17 inch

    Not sure if this model would fit the 32gb RAM and additional NVMe with 1 TB.

    I checked with LG they would place it in but no guarantee that it will work.

    I checked the CPU that’s inside the laptop and it shows support up to 64GB on the intel Web page.

    For the NVMe I was looking at a crucial p2 1tb but not sure if that one will work.

    Thank you.

  • Good work JC. I just did this and super easy except for the scary part of removing the back cover with plenty of cracking sounds. I just used a credit card to gently pry it open and all was good.
    Used the 3200mhz memory and an Intel 2TB ssd on the 17 incher I bought in December 2020 at Costco. Works fine in both the Windows 10 and Ubuntu that I have on separate partitioins. Noticed that my version has an 80wh battery versus your 72wh.

  • Hi,

    upgraded my laptop with 32GB RAM. Works all fine.
    Had to wait ~20s at the first boot to detect the RAM.

    RAM: HX432S20IB/32 (Kingston HyperX Impact 32G 3200)
    Laptop:17Z90N-V.AA77G (Lg Gram 17″ 2020, German)

  • THANK YOU FOR THIS! This is exactly what I was looking for and your article was super informative and helpful. Will reach out to you if I have any questions regarding this.

  • Upgraded Costco $1249 LG 17Z990-R.AAC9U1 to LinuxMint 19.3 in February. Removed the Windoze NVME (in case I had any problems and had to return it to Costco with Windoze) and replaced it with 500GB Samsung 970EVOPlus NVMe as boot drive and 2TB Samsung 970EVOPlus NVMe as my media drive. Works great! Have not had any issues.

    Was leery at first about not have 1GB ethernet, but the WIFI works at >400Mbps which acceptable.

    This replaced my ASUS G752VL boat anchor.

    • Most ultrabooks these days do not have a physical ethernet port; and many do not care to ship any kind of adapters. So this isn’t anything unique about the LG Gram.

      A decent usb to gig eth adapter sells for about 25$.

          • Is the port not working or the dongle? If the dongle isn’t working – I wouldn’t worry too much – if it’s the USB-C port – then that’s something else.
            Make sure you have all the drivers updated on your system and no errors in device manager. (the SDI utility works pretty good, http://www.sdi-tool.org)

          • My 2019 Costco model (17Z990-R.AAS7U1) came with a USB-C to Ethernet dongle as well, it is only 100MB however, not 1GB. It does work fine with windows 10 pro though, and shows up as “Realtek USB FE Family Controller” under Network adapters in Device Manager. Realtek Driver version 10.28.1002.2018 dated 10/2/2018. I have replaced it with J5 Create JCA374 ($59.99 at Best Buy) which gives me a Gigabit ethernet port as well as 2 USB 3.0 and another HDMI. It shows as “ASIX AX88179 USB 3.0 to Gigabit Ethernet Adapter” in device manager.

  • Opening up the back of my gram damaged some of the little small plastic screw covers. Does anyone have a source for replacement covers?

  • I got a LG Gram 17 17Z90N V.AH75A2. I also installed 32GBof SODIMM Kingston ValueRAM which isn’t getting detected. can anyone confirm this particular model’s max RAM and SSD capacity?

    • Were you able to increase the ram? I am planning to buy the same laptop and increase RAM and SSD size. If you can post the pictures opened back panel, it would be helpful.

  • Hi Jay, thanks for the great article! I’m confused with single/dual rank ram. Is there any difference when added to my LG gram? Appreciate it!

    • Understood, this is a tough question.

      From what I can find online. I found this. But, some also mentioned that single rank is faster. I am not too familiar with how this can affect ram speeds.

      “Generally speaking, single ranked and dual ranked has to do with the number of chips on the module. Single ranked will typically have less chips (higher density), where dual ranked will have more chips (low density). There is no performance difference between single and dual ranked parts that all other specifications are the same.”

  • I finally got around to upgrading my 2020 Gram 14Z90N with an additional 16 GB of RAM and a 1TB 970 Evo Plus. Jay’s instructions were right on point.

    The only problem I ran into was the single screw in the empty 2x NVME slot was in so tight I barely got it out. Once I did that I thought I’d check the 4x slot screw holding in the stock 256GB NVME and it won’t budge. Arrrrrggggh… I was planning on cloning the stock drive to the new NVME, removing the stock one and use the 4x slot for better performance.

    Anyone know how to get a stuck screw out without damaging the mobo or NVME? Better screwdriver? Some lube that won’t F up the mobo or NVME?


  • Has anyone upgraded from Windows 10 Home to Pro? Was the process seamless or did it require any driver upgrades from LG?

    • Three things to note:
      1 – You have to go into BIOS and disable Secure Boot – otherwise, you won’t be able to boot to anything other than the OS.
      2 – The Win 10 Home Serial is baked into BIOS – so if you decide to wipe and install a clean version – you’ll need to add a very basic ei.cfg file to the \sources folder on the flash drive.
      3 – Even the latest Win10 ISO (Oct 2020) does not include drivers for touchpad – so you will need a USB mouse to navigate or use the keyboard. (and yeah, you will need the drivers from LG and Intel)

      • Thank you so much for the reply.
        Can I ask you to provide a more detailed step by step process please?
        I’ll use the Upgrade option in Windows settings menu and input the key for Windows Pro. Appreciate the help very much

        • Option 1: (Keep all the stuff as is, in place upgrade to Win10 Pro)
          Setting – About – Change product key… Paste the Win10 Pro Key and that’s it.
          No need for anything else because the source files are the same – Pro just unlocks some extra features. Laptop ships with Win10 v1909 – so you can download the latest v2004H2 Media Creation utility from Microsoft and select Upgrade this PC now. Follow the prompts and that’s it. This will keep all the original LG software installed and recovery partition intact.

          Option 2: (Wipe the drive, clean install of OS, upgrade to Win10 Pro)
          Use that utility from Option 1 and create a bootable USB flash drive. (you’ll need at least an 8GB one).
          Hold down F2 or F10 at reboot to get into BIOS and look for the Secure Boot option and disable it. Also change the boot order and reorder the list to put your new USB drive above the Windows Boot Manager.
          When it boots, it should boot to the Windows setup – and from there – you can wipe all the partitions – and follow the prompts to setup Windows on the empty drive. (Remember not to connect to WiFi if you want a local account instead of a Microsoft cloud one). When you are done with that – then connect to WiFi – to get all the updates. You shouldn’t have any “yellow !” devices after that process finishes.
          You’ll want to download the Intel Driver utility tool (website can scan system and tell you what’s out of date), and there’s a similar one from LG which will scan and update any specific items.
          Then follow same steps in Option 1 to upgrade Home to Pro and that’s it.
          Hope that helps.

    • I have upgraded in place before, and would say it was seamless. No new drivers should be needed.
      I presume you have or will be getting a valid Windows 10 Pro product key, you should be able to just update your Home key with a Pro key and it should churn a bit and then be done. See https://support.microsoft.com/en-us/windows/upgrade-windows-10-home-to-windows-10-pro-ef34d520-e73f-3198-c525-d1a218cc2818
      I can’t instantly test this out without getting a solid backup of a Windows 10 Home install before messing with it.
      One place to get the Pro key:

      Obviously you should consider some sort of image backup first, just in case.

  • Thanks for all the insightful notes here.

    I have the 17″ 2020, and thinking of adding a WD Black SN850, which is a pretty beastly SSD. From some comments it appears such an upgrade could reduce battery life quite a bit? The battery life is one reason I got one of these laptops. Is it better to downscale a bit on the SSD spec side to keep the battery life reasonable?

    Thanks for any help!

    • I’ve upgraded mine to 40 GB RAM and my next step is going to be to upgrade both hard drives. I am definitely going to try and find The Sweet Spot. I don’t believe having the fastest most awesome hard drive is going to make a huge difference in this laptop as it is not a gaming laptop. It is a travel laptop that has very limited air flow and is super thin and Light. So increasing the size of the hard drive and not focusing on the speed of the hard drive is what’s going to be paramount for me. I do not need to have overheating issues which will ultimately cause the battery to not perform as well and could lead to other hardware issues in the future. How much of an actual noticeable gain in performance will you get with a monster hard drive when the rest of the computer is basically a middle of the road or slightly better configuration?

      • Agreed! I ended up ordering the Samsung 970 EVO Plus 1Tb. I do heavy optimisation work with thousands of file reads and writes per minute, but at the same time the SSD performance will be limited to the rest of the laptop anyways. And now I have extra cash left for RAM 🙂

  • First of all, thank you Jay Chen for this page. It is what tipped me over the edge to to buy this laptop. I was quite adamant on having a laptop that could up upgraded to 32 GB minimum. With the missing information on the Crucial website, I thought this machine could only go to 24 GB.

    2020 17′ LG Gram model 17Z90N-R.AAC8U1 – Costco, in warehouse, Oct 2020. (Bought in US)

    Upgraded RAM to 40 GB using Crucial 32GB Single DDR4 3200 MT/s CL22 SODIMM 260-Pin Memory – CT32G4SFD832A – Amazon.ca (From Canada, 2 day free shipping with prime)

    Recognized at boot, no issue. Startup takes a bit longer than usual. Screen is black for a few seconds.

    Added 1 TB SSD Crucial MX500 1TB 3D NAND SATA M.2 (2280SS) Internal SSD, up to 560MB/s – CT1000MX500SSD4, Multicolor – Amazon.ca (From Canada, 2 day free shipping with prime)

    I used the following process:
    Added new SSD to the 2nd slot.
    Cloned the original SSD Using the Acronis drive util from Crucial
    Removed original SSD from first slot, replaced with new SSD.
    Boot with only new SSD
    Added original SSD to second slot
    Reboot. Both drives visible. Boots from new drive.

    Had the laptop about a week, traveled with it. It was a good machine pre-upgrade, and is a great machine post upgrade. At $1500 US for the laptop and $250 USD for the upgrades, it is a great laptop for an ever better price.

  • I change ADATA XPG SX8200 Pro 2TB to TOPMORE 2TB M.2 2280 PCIe SSD, in the Slave sLot. It’s working now, I also upgrade RAM by Patriot DDR4 3200 32GB(8G+32G = 40GB).

  • I ordered ADATA SPX 8200 Pro 1TB. It doesn’t work in the Slave sLot. The system can only see 1GB size. You can’t format the disk. I can use Diskpart to clean and convert it. However, it just not recognize the disk.
    Unfortunately, I can’t remove the 256G Samsung from the Master slot. The screw won’t budge. So I can’t test if it works in there.
    Kind frustrated. But I guess it is what it is.

    • Me too, I use ADATA XPG SX8200 Pro 2TB, in the Slave sLot. The system can only see 1GB size, but you can’t do any thing.But change to 512GB and 1TB is ok.

  • for how long it charge 17 i7 2020 version?
    mine with 40gb ram, evo plus charges to 100% for 4.5hours
    and works on battery for about the same time, its only me have so low working times? and long charging times?

      • On my LG 17″ Gram 2020 with Android studio, music on youtube and the android VM emulator I have 4h to 5h of battery
        The CPU regularly goes to 90/95 degrees when doing dev. Stays at ~60 when using only the web browser.

        The same computer idling (turned on but doing nothing, apps closed) all night long uses ~50% battery in 9hours.

        Tested on Ubuntu 2020.04, with stock 17Z90N-V.AA77G, room at 21 degree

        So it all depends on the load of the computer. (Who would have guessed ? :P)

        • Thanks for that note. I plan to do this upgrade to my machine and I run ubuntu as well. In fact I bought it specifically because it doesn’t use an nvidia card which is the death of linux laptop batteries.

  • I successfully upgraded the RAM on my LG gram 17 (2020), 17Z90N-V.AA75A1 (UK model) to 40GB using Crucial 32GB Module CT32G4SFD832A. First boot after installation took a minute or so but subsequent reboots were normal.

    I also fitted a Samsung 970 EVO 1 TB PCIe NVMe M.2 (2280) SSD (MZ-V7E1T0) but replaced it with a Crucial P1 1 TB CT1000P1SSD8 SSD as the Samsung being a supposedly faster drive heats up and throttles almost immediately. Although the Crucial SSD is in theory significantly slower it’s actually faster in use as it throttles less. Note that there is limited room to fit an SSD heatsink although a very slim one will fit.

    • Is anyone else using Acronis True Image 2020 to create backup disk images? I’ve found that with an SSD or NVMe M.2 drive connected in a caddy to a USB 3.0 or the Type C port that Acronis slows to a crawl and it can take up to 30 minutes (I usually give up well before then) just to enter the settings for the backup. The backup itself seems to take the usual amount of time to complete though once initiated.

      Removing all external drives and backing up to an internal NVMe M.2 drive seems to function nearly as normal albeit a little bit slower to enter the settings compared to my other laptops.

      Entering the settings for a Macrium Reflect disk image just whizz by in comparison.

      It’s obviously a problem with Acronis and the way the USB ports or drivers are set up but does seem unusual. I may perform a reinstallation at some time just to see if it makes a difference.

      Anyone who’s dealt with Acronis on resolving problems knows it’s a waste of time as it’s always the users fault so I haven’t bothered contacting them yet.

      Anyone else with a similar experience with Acronis or other software?

  • Is there any reason why a 2 tb nvme m.2 like the one from Adata or Sabrenent wouldn’t work? Since the prices have come down, I’m thinking a 2tb drive + a 32gig ram upgrade in my costco LG gram from 2019

    • Any nvme m.2 will work. I have links to Samsung as those were the m.2 that I used. Samsung m.2 are just known to have better TBW.

  • Hi Jay or any other reader,
    I have the LG 17 Gram – 17Z990-VAA7CA3 laptop.
    Would this model take an additional 32gb of ram?
    Presently I have 16gb ram. The local LG service centre said no, this is the max it can take but reading from here it might not be the case. It has the Intel® Core™ i7 Processor. Here’s the link the the models page.


    Thanks in advance.

    • It looks like the LG gram model that you stated is an international model.

      The only way to know if you have the available slots is to open the laptop and see if the removable ram is 8gb.

      • Hi Jay, thanks for your reply.
        There is one slot for additional ram. It came with 8 on the motherboard and they had a free upgrade which they installed an additional 8 in the slot. I haven’t looked inside, but that’s what I was told, which seems the same for the 17Z990 gram laptop.

          • I did a system check, under device specifications, the processor is “Intel(R) Core(TM) i7-8565U CPU @ 1.80GHz 1.99 GHz”
            I think this is the same as the link you sent me?

          • Nope, it’s the same processor as the one on the link I sent.

            Processor is independent from the motherboard.

          • That’s some great news. Thank you.
            My only concern, when I contacted LG, they said this 16gb ram is the max, clearly it’s not, but my laptop is still under warranty and if I break the casing trying to insert the ram or the motherboard fries at some point I then have no warranty. (I also got an extended warranty for the machine so 2yrs from LG and an additional paid 2yrs). The machine was purchased in Febuary this year. What are your thoughts? I’m not sure which path to take. Of course if something went wrong with the machine I would swap over the ram before I took the machine in.

          • My lg gram did not have any tamper tape or anything that prevents it from being opened. They even left a empty nvme slot for people to upgrade.

            In the event that it breaks, just put all of the original hardware in place and you will have warranty.

  • Hello Jay,

    Thanks for the nice blog with pictures on how to upgrade these awesome LG Gram workhorses.
    I bought my gram from costco 5 months ago and it’s a 2020 15.4 Core I7 10th Gen 16GB 512GB model. It came with Windows 10 Home but I upgraded it to Win10 Pro.

    Since then, I’ve been waiting for good deals to upgrade my unit. Finally, 2 weeks ago I ordered 1TB Western Digital NVME (https://www.amazon.com/gp/product/B07YFFX5MD) and Crucial 32GB RAM stick (https://www.amazon.com/gp/product/B07ZLC7VNH) from Amazon. I also ordered a good tool set (https://www.amazon.com/gp/product/B07YY4T7DZ) for this purpose.

    Today, I am happy to announce that everything went well and both RAM and HDD were upgraded successfully. Basically, I removed one of 8GB sticks and replaced it with a 32GB one. I added the new 1TB NVME HDD in the additional slot to make total HDD to 1.5 TB.

    My PC is working fine and no issues. Let me know if anybody has any questions.


  • Hi Jay,
    quick question – do you know if this will take a double-sided nvme (like PNY or ADATA XPG SX8200 pro or only a single sided nvme (like samsung or toshiba) will fit in the slot.


    • 2 x PCIe 3.0 (4 Lane and 2 Lane)

      I believe most laptop are still on PCIe 3.0 as the 4.0 are only available on Desktop motherboard like the x570. PCIe 4.0 NVMe usually also requires a heatsink which doesn’t fit in a laptop.

  • Hi,

    I just wanted to thank you for this great guide and contribute with another working memory upgrade.
    I upgraded my 2020 Lg Gram 17Z90N to 24GB, using a 16GB SODIMM from Kingston ValueRam (DDR4-2666), product code is KVR26S19D8/16 and it works. BIOS shows that RAM is working at 2666Mhz, as expected. I just had this SODIMM module from my previous laptop and decided to test it in the Gram.
    If you have to buy new memory, buy DDR4-3200 as it will be a little faster.
    The 8GB module that was factory installed is a Samsung branded DDR4-3200 SODIMM and is now installed and working on my previous laptop.

  • Hello, i found that there is something strange with my Wifi.On Gram 17 2020.
    I upgraded windows to Win10PRO.
    And i mentioned that there’s no any usual options in power management.
    How you can see: https://ibb.co/zb57dZM
    I have only one mode – Balanced (i didnt checked if there was other options before i upgraded from original Home)
    And inside of it no Wireless Adapter Settings
    No USB setting, Power buttons and lid, PCI express etc..NOTHING.Just what you see on the picture.

    In device manager ALSO no Power Management button: https://ibb.co/ccMwmTk

    I googled, tried some commands, but NOTHING changed.
    I installed newest driver from Intel – still nothing.
    What is could be?
    And how i mentioned sometimes ping is not so stable, but from another laptop ping times is stable.
    Anyone can advice what to do? Power Management and ping issue?

  • The information on this page is very helpful. Thanks everyone.
    I my case I just bought a lg gram 14 in 2-in-1 Model 14T90N. Does anyone know that I can upgrade the memory to 40GB as @Mark & @Justin did for the Model 14Z90N

  • can someone recommend Laptop Sleeve for 17inch Gram?
    Such that it would fit perfectly into it and could be put in a backpack?
    And that there were pockets where you can put all sorts of silences.
    My 17 Gram fits perfectly in my Backpack (just as it is), but putting it in the Laptop Sleeve that I bought, it doesn’t fit in my backpack
    I bought https://www.amazon.com/dp/B07YH3H534
    and it doesn’t fit my backpack 🙁

  • Did somebody install Win10 Professional on Gram?
    I mean fresh install from Microsoft generated installation usb drive on new internal SSD.
    I wonder if fancy volume controll, power button finger scanner and others would work directly?
    Or some driver package from LG would be needed?

  • hello, are you sure that in my lg gram 2020 17inch will fit +32gb
    i opened inside
    and i see that 1 slot for memory is empty.and system shows that i have 16gb already.
    maybe in my configuration 16gb already installed as unswapable, so i can add only 24gb to get 40gb?

  • who tha f*** posted
    (Crucial Single 32GB 3200 Mhz – 1-2 Month Wait) *Confirmed Working

    works with lg gram 2020?its totally incompatible, it is double size that needed, i wasted money and time, i hope these person will burn in hell.

    • Hey Viktor, the link changed. I will update shortly.

      For laptops, it has to say SODIMM or it is not compatible.

    • I just updated all of the amazon links that were pointing to the wrong product.
      Sorry for any inconvenience.

  • I have 17 inch 17Z90N with 16gb of memory originally, i didnt understand, if i put additional 32gb plate i will get a 40gb and laptop will boost? Because 16+32=48gb, im not sure that it will work with all of these?

    • The laptop comes with 8gb on board (non-removable) and 8gb removable.

      The goal is to switch out the 8gb removable for the 32 gb.

      16gb – 8gb + 32gb = 40 gb

      • thanks.
        but how i can be sure that there is not 1 16gb in 1 slot and second slot is free?
        i checked in BIOS – shows 16gb (no info about slots)
        i checked in AIDA64
        Memory Bus Properties
        Bus Type Dual LPDDR4 SDRAM
        Bus Width 64-bit
        DRAM:FSB Ratio 24:3

        Used 3343 MB
        Free 12751 MB
        Utilization 21 %

        im asking because i dont have screws now to check…
        maybe i can check by any program that in 1 slot is 8gb and in another 8gb?

  • Jay, thanks for the explicit instructions on the Gram upgrades. This is the best site I’ve found on how to upgrade both NVME SSD and RAM.

    I have a 14z90n gram that I’d like to upgrade with a 16GB 3200 RAM stick and a 1 TB 970 Evo Plus. I get that I shouldn’t upgrade the RAM until after the NVME upgrade, but I’m wondering if I can do this:

    Clone the existing 256GB factory NVME *exactly* on to the new NVME 1 TB drive. I.e. All partitions are cloned exactly, including the recovery partition, GUID, etc. Then use the remaining space on the TB drive as a new partition (e.g. ‘D:’ for data and/or programs). I’d remove the original 256GB NVME drive and keep it as a backup. I’ll note that I’ve upgraded the Windows 10 from Home to Pro on the original NVME drive. I’m assuming Macrium Reflect can do this. Let me know if I’m wrong and if no one knows, I’ll run the experiment myself (because science :))

    Jay installed from scratch onto the new NVME drive. But can anyone else give me feedback on whether my process is do-able? I’m wanting to keep the recovery partition on the 1 TB drive and have a backup in case things go south. Plus, it gives a way to add another (albeit slower) NVME drive in the vacated NVME slot.


    • Your directions sounds correct, when you use macrium reflect to clone the drive, your NVME 1 TB should only have 256 GB cloned. The remaining space will be around 744 GB and you could probably initialized that as the “D” drive.

  • I need some help if possible.
    2019 model.
    Bought exact 32gb ram you linked from amazon and exact samsung 970 evo plus you linked.
    Intent was to do this update directly, LG new from box never been used before.

    Turned on LG and signed into windows 10.
    Downloaded the samsung migration tool.
    Powered off PC.
    Followed your instructions to remove back,
    move original SSD to the x4 slot to x2 slot
    install 970 evo into x4 slot
    removed included ram
    installed 32gb ram
    Flipped computer over and power on: booted fine.
    Checked system settings confirmed the 40gb memory
    ran the disk management on Disk1 and it said it recognized it fine.

    Went back to samsung site and read manual for the migration software. It said i needed to install the NVMe driver before the migration. I downloaded and ran this. I presume this automatically installed to the ORIGINAL ssd–>it says the target drive will be overwritten so I assume we’re trying to have the NVMe driver on the source drive.

    Ran the migration tool, it completed in about 7 minutes and did its autoshutdown.
    Blue screen “inaccessable boot device” upon power up.

    How do i proceed. Have a brand new laptop here that won’t boot.

    • Should add, if solution is fresh install of windows, i don’t see a license key sticker anywhere on the LG box the laptop came in or on the laptop itself. Would need to know how to obtain the license key before wiping windows.

    • Sorry for the repeated additions, but just tried something that is probably relevant:
      I can unplug the 970 EVO from the x4 slot and it boots fine
      I can leave 970 EVO in the x4 slot and remove the original SSD from the x2 slot and it boots fine.

      I’d be interested to know if the problem is that both SSDs contain the OS. I don’t foresee my use of this requiring the 2nd (original) 256gb SSD, so as long as you don’t think there is any underlying other things wrong with what I’ve done, I could simply store it in the box the EVO came in as a virgin “brand new” backup for the laptop? And if i needed more space in future could simply add another 1TB to the x2 slot?

      • Yes, both drives can’t have Windows OS. I will add an update to my blog.

        You can leave it in the original box as a backup for warranty and buy another drive to replace it when needed.

        However, If you want to use it, you can use a Windows ISO installer USB to wipe the drive.
        See the directions in my comment to your first post.

    • Try opening the laptop’s Bios and make the laptop boot from the original drive. (Google for the instructions)

      If you’re able to boot from the original drive, you can wipe the target nvme drive with disk manager.


      If that doesn’t work. From another computer, install Windows ISO onto a USB.


      Plug the usb into the laptop. Go to bios and boot from the usb. Use the Windows installer usb to wipe the corrupted drives.

      At this point, you can wipe the individual corrupted drive or both drives. However, you will need a new license key if you wipe both drives. You can buy from Microsoft or Third Party (ebay, etc) and upgrade to a Windows 10 Home or Pro. (This is what I did for my laptop to avoid migrations)

    • I had a similar problem, also had “Innaccessible Boot Device” when replacing the SSD with an NVMe (taking a backup, restoring to the new NVMe on another system, installing it n the motherboard and removing the existing SSD). The problem as that the NVMe storage driver was disabled as boot time, so it couldn’t find it after the boot handoff between BIOS and Windows. On the next boot, it would go into automatic repair, and fail.

      I had to go into Advanced Options in the Boot Recovery Environment and boot into safe mode, and then I was able to run this command to enable the driver at boot time.

      sc.exe config stornvme start= boot

      As described in https://superuser.com/questions/1640562/inaccessible-boot-device-after-m-2-ssd-upgrade

  • What is the maximum upgrade capacity for the SSD storage for 2020 i7 LG Gram 17 ? Can I add a 2 TB SSD to the onboard 512gb? And is there a compatibility issue with brands other than Samsung?

    • There should be no limits on the upgrade capacity for SSD storage. You’re basically limited to how much you can afford $$$ (e.g. 2 x 4TB SSD).

      You should be able to use any brand, however, in my opinion, Samsung has the highest performance in terms of speed and longevity.

      • Thank you for the update and for calling me poor on the internet 😛 I wanted to add a Sabrent Rocket NVMe. Hadn’t thought about 2x 4TB. Hmmm… My kidneys feel itchy all of a sudden. It would be great if you could also write a blog on NVMe SSD cloning. Thanks anyway. Cheers!

        • Lol haha 😂.

          I didn’t clone my ssd, I wiped my drive and reinstalled Windows for my LG.

          However, other people have use macrium reflect to perform a drive clone.

  • Has anyone benchmarked the RAM before and after upgrading it?

    I’m wondering if the switch from dual (2x8gb) to single (8gb+something else) channel has a noticeable performance impact.

    • The additional ram will not significantly increase performance but it will increase ram capacity.

      For example, Google Chrome will not run faster but you can have more tabs open before Chrome crashes.

      If you’re running a virtual environment using virtualization softwares like VirtualBox, you have more ram capacity for multiple virtual machine instances.

  • Hi Jay. Apologies to all if this may have been covered but I just didn’t have the time to go through all of the responses. I added a new 1tb evo plus to the second slot and also the hyperx impact 32 gb ram. The ram installed fine and the new drive appears everywhere. Then I cloned the original drive to the new one using samsung data migration and it went fine. Then I opened the laptop again to swap the 2 drives around so that I have the new one in the first or better slot. The drives do show up but the original drive is still the windows drive. I went into Bios and here is what I see in the boot section:

    Boot Priority Order
    1. Windows Boot Manager
    2.usb cd:
    3.ata hdd1:
    4.ata hdd2:
    5.NVMe1: Samsung SSD 970 evo plus 1 tb
    6.NVME2: Samsung MZVLB512HAJQ-00000
    7.usb hdd:
    8.usb fdd:
    9.usb lan:

    What do I do now? What settings should I change and how?

    Thank you in advance.

    • The new drive doesn’t have Windows. I recommend cloning your drive.

      Samsung Data Migration software is designed to help users quickly, easily, and safely migrate all of their data – including their current operating system, application software, and user data – from their existing storage device (e.g. HDD) to their new Samsung SSD.

      • Thank you. Not sure I understand. It seems that samsung data migration only moves files across and not the intact operating system – it didn’t seem to clone it properly. But when I compare the results, it looks the same and shows that windows is on the new drive. So are you saying that there is nothing that needs to be done via bios but that I need to do another cloning? I did the same a few days earlier with my son’s new acer and I used macrium reflect which worked perfectly. I will use macrium for my lg gram too. Based on my experiences, I would definitely recommend macrium over samsung data migration.

        • Other users on here also had success with macrium reflect. Just remember to expand the space of your drive after you clone it.

          You can check disk management to expand the unallocated space.

  • Hi Jay

    Thank you so much for this post. Using the direction you’ve provided, I got myself a LG Gram 17 and upgraded with all the parts you’ve listed.

    BUT one thing I’m noticing is that the Samsung 970 EVO Plus seems to be heating quickly quite often. Under normal conditions, it’s running at around 65C-70C. This is alarming me.

    Have you experienced the ssd overheating after you’ve upgraded?

    Any ideas or suggestions you’d like to provide?

    Thanks in advance

    • I have the 2019 model, and I haven’t experienced any overheating. I been using the laptop since Aug 2019.

  • I have the 2020 model and it gets very hot even when I am just surfing the web. Does anybody else have these issues and if so is there any type of fix? Thanks

    • My 2020 17″ Gram definitely gets hot. It’s tolerable if the laptop is open, but uncomfortably hot if the lid is closed (I set mine to keep running when closed — I don’t want it sleeping just because I closed it for a quick grab&go).

      When the CPU gets hot, the fan turns on, and it blows hot air out the back of the laptop base-half. At least on my 17″, that back edge of the base-half is pretty snug up against the bottom of the screen-half. There does seem to be enough gap for air to escape.

      But when the laptop is open, the fan-blown hot air escapes both upwards (in front of the screen’s bottom bezel) and downwards (toward the back center rubber foot). If the laptop is closed, hot air escapes only downwards, and that’s when mine gets intolerably hot to the touch.


      • I also have the 2020 model and am concerned with how hot it gets. The area between the keyboard and LG logo on the screen gets really, really, really hot.

        Kel is spot on with how the air blows out of the laptop.

        Now despite it being crazy hot, I haven’t had any issues with it overheating and I run a lot of CPU intensive applications. What I am mainly concerned with is the longevity of the laptop due to it consistently being so hot.

        So when I have my laptop hooked up to an external monitor, I always keep the laptop screen propped up so air can circulate.

        I also made two 1″ tall pedestals that I put under the laptop feet by the screen, so the back of my laptop is propped up to help air circulation. This works really well and I found the laptop stays cooler.

        • I added a 0.2mm copper shim (available from eBay) onto the CPU and one onto the GPU using Coollaboratory Liquid Pro on either side of the shim and also fixed a slim copper NVMe heatsink onto the CPU/GPU heatsink. Load Temps have reduced by around 20ºC and mine no longer throttles.

          The design of the heatsink and heatpipes are extremely bad as firstly they’re too small and secondly the heatsink fixing mechanism (simply screwed down) doesn’t allow for manufacturing/fitting tolerances. Some sort of spring loading would have helped.

          The fan although quiet is simply not up to the job and I’m planning on replacing it although that’s purely to see if I can reduce the temperatures even more but don’t plan on that necessarily being a permanent replacement. The difficulty is finding a suitable replacement as it appears the current fan is a ‘one-off’ rather than an ‘off the shelf’ item.

          I made a 4 fan cooling pad using Scythe Gentle Typhoon 1850rpm fans. It makes no difference to CPU temps and only knocks off around 4ºC from the SSD temps.

        • I didn’t take any photos but the shims are fitted between the LG heatsink and the bare CPU and GPU die which do not have IHS fitted. The Liquid metal paste is use on both sides of the shim that come in contact with the CPU & GPU and heatsink. I don’t think normal thermal paste will be as effective as the metal paste with the shims based on previous experiments.

          Your photos don’t show the die with the heatsink removed. The image here shows the layout:


          Please note my previous warning about the possible difference between the layout of the dies on different models an the possibility of conductive components also being present

  • Thanks for the excellent and detailed instructions. I used them to upgrade my 2019 Gram 17 to 24GB using a Samsung 16GB DDR4-2666 SODIMM left over from upgrading another computer (waste not, want not) and while I was at it, put in a 1TB Intel 660P I had lying around.

    I didn’t want to fiddle with a knife around the case edge, and I have a high-strength suction cup at hand (from a Manfrotto pumped suction camera mount), I just used it to pull at the bottom plate and it came right out (be careful not to apply too much suction, the plate will warp otherwise).

  • Confirming that HyperX Impact 32Gb 3200MHz works on 2020 LG Gram 17″ 16Gb RAM 1Tb SSD.

    In OEM configuration, with the laptop running a bunch of applications simultaneously (MS Edge Browser, Teams, Outlook, Powerpoint, Word, Excel, QuickBooks, Malwarebytes, Windows Explorer), every 30 minutes or so the computer would freeze for about 5-8 seconds (no mouse, nothing). Then the screen would go black for a split second, and everything would come back including whatever was my last mouse click. Task Manager would show 45-65%+ RAM used. I figured it was a memory issue.

    After reading some sites including JayChen here, I opted for the 32Gb instead of 16Gb. Now no more freezes, Task Manager shows 15-25% RAM used. Control Panel/ System Security/ System shows: “Installed Memory (RAM): 40.0 GB (39.7 GB usable)” YEAH BABY.

    Super pleased. Thanks JayChen for the detailed instructions, very helpful! On the 17″, after all screws were out, I had to pry around the sides and front, then get the cover next to the hinges to unclip (very important or you can’t tilt the cover up without bending it), then tilt the cover up from the front a few inches and push down on the back cooling grill while tilting. Pushing down on the back helps to disengage those rear securing spots. Work it and don’t force it.

  • That’s the one I did dude! Works Great with the 970 EVO plus and the HyperX linked above. Give it a good solid, very anxious, two minutes after the RAM install on your very first boot. So fast…

  • I’m getting a 2020 Gram 14 from Costco (i7-1065G7, 8GB/256GB), any reason to believe upgrading that one will be dramatically different?

    • Hello Lars,

      I just upgraded that exact same model and my wife’s 15″ LG Gram with a 2x32gb sticks that Amazon sold (one day only) for $49.99. No issues, and the MHz of the new sticks are 3200, while the originals are only 2666MHz, again no issues.

      I am going to hold off until I can figure out which HD is best…. not for performance, but for the heat issue.

  • Confirmed that the hyperX 32G 3200 that you link works in the 14 inch Costco model 14Z90N-U.AAS6U1. Got it booting both Windows and Arch on a 1TB EVO. The fact that this thing supports these upgrades, and that ctrl-alt-F7 in bios enables a shit ton of options makes this my favorite hack in a long time. If the EFI on it let’s me add keys and sign my Linux boots as well, it’s going to be just about perfect for my purposes… thanks a ton for this page, Jay. Thanks for paving the road, all.

  • Do you see a noticeable difference in performance after upgrading? I want to use the gram for video rendering but I heard video editing depends more on CPU performance than ram. I was wondering if upgrading the ram to 40gb would offset this limitation.

    • When running your video editing software, if the ram caps out, then it is worth it to upgrade. If not, the rest of the performance of video rendering is dependent on graphic card and cpu.

  • After reading about people’s problems with drive upgrade and migration, I got an idea: what if I create recovery drive form my original disk, then remove the original disk and put in only the new hdd inside (to prevent any confusion and accidental booting), use the recovery drive to install new windows on my clean fresh hdd?
    Do you think this would work?
    I would all the time have the original factory hdd with factory windows, in case something goes wrong I can stick it back in and troubleshoot.

    • I have not tried that method yet, but I believe Windows Recovery Drive might require a drive that already has Windows operating system.

    • I highly suggest checking out Samsung Data Migration.

      Samsung Data Migration software is designed to help users quickly, easily, and safely migrate all of their data – including their current operating system, application software, and user data – from their existing storage device (e.g. HDD) to their new Samsung SSD.

  • Hi,
    thank you for this great tutorial!
    I’m new to self-upgrades, but I would like to try. I’m going to get the 2020 model, and I’m going to upgrade RAM to 40GB, and put in second ssd.
    I bought the same RAM that’s reported here to work, CT32G4SFD832A. I couldn’t find it anywhere in the US so I ordered form the UK, fingers crossed.

    I have ssd question: will this one work: Samsung 970 EVO Plus SSD 2TB – M.2 NVMe Interface Internal Solid State Drive with V-NAND Technology (MZ-V7S2T0B/AM)?
    I’m not very familiar with technical specs for computer parts, I never upgraded laptop parts before. Thanks!

  • Thank you, Jay. Great breakdown. I am concerned about the 10/100 ethernet limitation of the LG Gram. Is it possible to upgrade that component? If not, do you see similar speed limitations over Wifi or is it only when using ethernet?

    • When you buy the LG Gram 17 laptop, it comes with a USB-C Ethernet Adapter.

      Adapter Specs:
      10/100Mbit (USB-C Port with R45 gender)

      You can buy a higher rated Ethernet adapter on Amazon and just use that.

      As for the Wi-Fi, the spec is that it is a
      Intel® Wi-Fi 6 AX201, which should be able to support 2400 Mbps connections.

  • I really apprecaiate all of you sharing your experiences. They’ll inform my next steps. So I picked up one of the 2020 models from Costco. Great experience even after the first unit had bad pixels. So to return/exchange with those guys. Anyway.
    My question is about adding RAM. I want to plug in a 32GB module, but I’m having trouble finding any that match the increased speed of this years model (@3200MHz).
    Amazon’s only offer is a 1-2 month wait (https://www.amazon.com/gp/product/B0848MD5Q6/ref=ox_sc_saved_title_1?smid=ATVPDKIKX0DER&psc=1)
    If anyone has a better source than this I would love to have it.

          • Hi Jay, what is your ETA for your 32 GB module?

            I was about to order the 16 GB module to upgrade to 24 GB (on the 2020 model), which we know will work, but may wait till you test the 32 GB module.

            For anyone who wants to know, this is the exact model of 8GB memory chip in the 2020 LG Gram 17: Samsung M471A1K43DB1-CWE

          • The user “Scott” is waiting on his single stick 32GB 3200Mhz SODIMM from Crucial, and he will let us know if the upgrade works in the new 2020 LG Gram 17.

            Link to the 32GB 3200Mhz SODIMM:

            Before you buy your 16 GB module, the new 2020 LG Gram 17 supports 3200Mhz ram instead of the old 2666Mhz ram. However, 3200Mhz SODIMM ram is harder to find right now.

            I am pretty sure that 2666Mhz ram will still work in the new 2020 LG Gram 17, but it won’t be at its highest potential.
            I am also not sure if the brand of the ram will affect compatibility. For the 2019 LG Gram 17, the Samsung ram worked perfectly fine, but they don’t have a 3200Mhz model yet.

          • Sorry Jay, I actually noticed I should have addressed “Scott” after I clicked “post”. 🙂

            I’m going ahead and purchasing the 16GB version of the 3200Mhz memory, which is this:
            I ordered it from Amazon and should have it in a few days.

            I’d caution everyone to be careful buying using the 2666Mhz memory until someone can really verify it will work. I came across this thread yesterday who tried 32GB 2666Mhz and couldn’t get the 2020 model to boot:

          • Yeah, I added disclaimers across the blog post. As for those willing to take a shot at it, let me know if it works out lol.

          • Upgraded my 2020 laptop to 24 GB last night from the default 16.

            Let me know if you’d like me to email any pictures of the inside, case, etc.

            My wife has the 2019 laptop, and there are slight differences in the feet and shell. Getting the new larger round footings off was a little challenging, and also getting the shell snaps to unclick where the new larger air vent is, by the hinge. But once it was finally apart, changing out the RAM out was a breeze, along with putting it back together.

            Again, I used the 16GB version of the 3200Mhz memory, which is this:

            Also as a FYI for anyone, the very first time you boot, after putting in the new RAM, it did take longer than normal to boot, but only the very first time. The following bootups are the typical lightning fast startups.

            I did not have to go into the BIOS to change anything.

          • I am glad that it worked out for you. If you have picture of the internal or laptop shell, you can send them to jay@ I will add them onto this blog, which will help those with the new LG gram 17.

    • Does anyone know if the 2020 version still nvme x4 and x2? Just trying to choose a 2tb secondary drive if I purchase (I know the primary drive is now nvme, i assume in the x4 slot.) Just wondering if things changed since it’s ice lake now, couldn’t find it in the specs. Thanks for all of this info so far!

      • Also, ice lake supports pcie 4.0, does this laptop then? Wondering if I can get a pcie4.0 drive like the sabrent rocket m4 or something. But maybe that’s overkill…

      • I believe that the internal setup is the same as the 2019 model. X4 and X2. However, Wayne or Scott can confirm later.

        As for the PCIe gen, it is probably gen 3 as they don’t advertise that information anywhere. In terms of functionality, gen3 is already powerful enough and gen4 will be overkill.

    • Life is Good

      I have installed the 32GB RAM and took some pictures (emailed to Jay) and everything showed up. I used Macrium Reflect free to clone the original 512GB drive, swapped it from the 1st slot to the 2nd and installed the 1TB drive. Booted to the original drive and restored the saved image to the 1TB. Now it’s my boot drive and the original is in the 2nd slot. Did need to find a utility to expand the C: partition after the image was restored, but “AOMEI Partition Assistant Standard Edition” did it for free!

      ask me questions but it went pretty well. Maybe 30 min, even with resizing that partition.

      • Hi, when you used Macrium to clone the drive, did you do it by creating an image of the active drive without plugging the drive to another computer?
        I thought it’s not possible to clone entire boot drive from software that’s on the drive being cloned. Am I wrong, and this worked for you? thanks!

        • Yes
          I selected the boot drive and chose “Image this disk…” &
          after selecting the Destination folder (my SD card) and Backup file name “_____.mrimg I clicked Next.
          The following screen allows a number of Backup Plan options (Template, Add/Edit Schedules, Define Retention Rules & Advanced Options), however I just chose the simplest backup plan and clicked Next/Finish.
          The program runs and I stopped there, installed my second,1 TB drive in the primary slot, moving the old 512GB drive into the second slot.
          I booted to the 512GB drive (via Boot select?), went back to Macrium and restored the backup image to my new 1TB. This restored image was only 512GB/1TB, the same as the original, but with the other software I mentioned, I was able to expand that drive to the full capacity of the new drive. And that’s it.

          FWIW – I think if you use the “clone” option on a boot drive, then you will indeed have issues with the cloned image. But I’ve been using the image option now for years and it works great. On my Mac Pro I use Carbon Copy Cloner.

          Thanks for reaching out, and hope this helps!

  • Dear Jay,

    Costco is currently selling the LG 17″ in 2 versions, one with 256G SSD and the other 512 G SSD. But the former has Intel UHD 620 graphics, and the latter has integrated graphics. What is the difference?
    Thanks for your help.

    • Hey pk,

      I just looked at the Costco website and see the two versions.

      The 256gb model says Intel UHD 620 and the 512gb model says integrated graphic. Intel UHD 620 is a integrated graphic, someone on their website was probably not consistent with the description.

      They did the same thing with the processor, for one they put intel i7 for 256gb model and Intel® Core i7-8565U Processor 1.8GHz for 512gb model.

      I am 99% confident that the processor and graphic card is the same on both models. They probably wrote different description to get more people to buy the 512 model.

  • I plan to only add the 1TB 970 EVO Plus.

    As with Will’s previous question I just put the 1TB drive in the second slot and boot up as normal?

    Is the Samsung migration software pre-loaded on the new drive or do I get it from Samsung later?

    Do I need to migrate if I keep the original 256 in?

    Would there be a benefit to then swapping the drives 1TB to slot 1 and 256 to slot 2?

    The machine is brand new so I have no info or settings as yet.



    • The Samsung nvme is much faster than the original drive that comes with the LG gram 17.

      The first slot is x4 and the second slot is x2. The drive that is in your first slot will run faster. It is most optimal to place the drive containing the OS in the first slot to increase boot time and loading speeds.

      However, You can use the computer 256gb as your original drive, and use the 1TB as your additional drive , but you will lose the benefit of having the faster Samsung drive to run your operating system.

      For the most optimal setup, you should place the original 256gb drive in the second slot, move the Samsung 1tb to first slot. Use the Samsung migration tool to migrate the OS from 256gb drive to 1TB drive.

      From the Samsung website, You can download the Samsung migration tool onto your original drive and perform the migration.

      After running the tool, go into bios and change the boot priority to the Samsung 1 TB drive.

      • I installed the new Samsung 970 plus in the first slot and moved the original drive to the second slot.

        I downloaded and ran the migration software.

        I restarted the computer and got the Recovery screen.

        I used Esc for firmware settings

        I changed the boot order to the 970 Plus first

        My computer will not start up now I only get the recovery screen. Did I miss a step?



        • Hmm..
          Try changing the boot order back to the original drive and see if it boots normally.

          The migration might have failed. If you can boot back to the original drive, you can wipe the 970 and try again.

          Personally, I haven’t tested the migration tool. I can only suggest watching YouTube videos regarding the migration instructions.

          During my upgrade, I installed my laptop using a fresh installation of Windows using a new key.

          Let me know how it goes.

        • Also….I removed the original drive and the system boots fine.

          I put the original drive back in slot 2 and restarts fine just doesn’t find the 256 drive.

          Under Disk Management it says that disk (256 Disk 1) has a signature collision with another disk (Disk 0).

          What do I do to use the original Disk?



          • It’s running fine off the 1TB drive now.

            I’m going to try disk management later tomorrow. My son (software engineer) will be able to guide me. I’ll let you know.



        • We fixed the boot order again and wiped the 256 drive.

          Seems to work fine now.

          Really appreciate the tutorial and support.

  • Jay, I changed the drive boot order and was unsuccessful. I was digging deep into the internet to see if anyone had solved it. There was even a mention with changing thunderbolt settings in the advanced bios (Alt+Ctl+F7). Also tried a smaller and older USB drive to see if it would work. Nothing.

    I finally gave up, pulled my hardware upgrade out, and was ready to return it to Costco. I figured I’d give it one last try. I reset the Bios to turn on the UEFI and secure boot, put in the USB and it finally worked. I loaded Windows 10 on the 512 SSD, then I pulled the 512 SSD and put in only my 1 TB SSD. I was able to successfully install Windows 10 on that as well. Now I put the 512 SSD back in, and put in my 32GB Ram back in. I changed the boot sequence to boot off the 1TB SSD and completely wiped all partitions off the 512 SSD.

    Now it’s functional, but it took a long time to get to it. 4 hours spent last night working on it.

    Here are my thoughts:
    1. Cloning the OS with Acronis didn’t create a properly bootable 1TB SSD.
    2. Wiping out the 512 GB SSD made the system unbootable at all and killed my ability to factory restore. (I had removed all the partitions on the 512 GB SSD).
    3. It appears that when the 32 GB Ram is installed, the system didn’t want to recognize a bootable USB
    4. Pulling the 32 GB Ram seemed to alleviate the bootable USB issue and UEFI and secure boot settings made no difference whatsoever.

    Recommendations for anyone upgrading the LG Gram:
    1. If you run into issues, pull your upgraded RAM out. There may very well be a RAM limit for the BIOS that we are exceeding with a 32 GB stick.
    2. Leave the 512 GB SSD as the boot drive and just use your additional drive as a data drive. This also protects your ability to restore the system to factory settings if you need to.
    3. If you want to make your drive seamless so that it appears you’re working off just one drive instead of two, you can use junctions and hard link your Documents, Music, Videos, Pictures folders to your D drive.

    These are the commands I use for hardlinks:

    Make sure your data is moved somewhere else and then delete the EMPTY folders from C:\Users\User1

    From Admin Command prompt
    mklink /d “C:\Users\User1\Documents” “D:\Users\User1\Documents”
    mklink /d “C:\Users\User1\Music” “D:\Users\User1\Music”
    mklink /d “C:\Users\User1\Pictures” “D:\Users\User1\Pictures”
    mklink /d “C:\Users\User1\Videos” “D:\Users\User1\Videos”

    Move your data back into the appropriate folders.

    This is how my desktop computer operates with a 1TB SSD for OS and program files while my data storage is on a 6TB Platter Drive.

    • Yeah, sounds like you had a difficult time getting yours to work. I am glad that it worked out for you at the end.

      Seems like the process will be different depending on how Windows is installed/migrated.

      For future reference to others trying to set up the laptop after upgrading.

      2 Different installation approaches:

      1. First approach: After upgrading the laptop, keep Windows OS on the original drive and use the extra drive as additional storage space. The downside is that you don’t get to benefit from the faster Samsung nvme for boot time and program load times.

      2. Second Approach: After upgrading the laptop, clone or perform a fresh install of Windows onto the new Samsung nvme. Do not add the ram until Windows is fully functional on the new drive. (Reassembly laptop only when everything works).

      Detailed description of approach 2 for Fresh install of Window (*Edited 12/15/19 Cloning/Migrating the drive should also work, however I do not have the steps for that approach)

      This process of installing Windows 10 on the LG gram 17 includes installing Windows With a new Windows 10 key that I brought online.

      After installing the hard drives. Google for Windows 10 iso, and download the installer from the Microsoft website.

      The installer installs the Windows 10 installation file onto an external USB. Afterward, plug the USB to the LG gram 17, visit the bios on computer startup and change the drive boot order to the USB.

      After booting to the USB, follow through the Windows installation menu and delete the partition on the original drive and perform a fresh install of Windows on the new drive.

      *To ensure that the upgrade is successful, only add ram after Windows successfully boots on the new drive. Make sure to change the boot order to the new Samsung nvme drive.

      *No other setting in bios needs to be changed

      • Hi Jay, Thanks for posting this article. I’m about to perform this upgrade soon. Regarding your “Second Approach”, won’t the Samsung Data Migration tool successfully clone the old SSD to the new SSD, including OS? I’ll be doing this on a brand new LG 17. Is there a reason I should purchase an additional product key & perform a fresh install?

        I’m about to perform this upgrade. Below are the steps I’m planning on taking. Let me know if this should work or if there’s anything I’m missing. For instance, will I need to make any BIOS changes? Thanks.

        Planned Upgrade Steps:
        1) Add new SSD to 2nd slot
        2) Download & install Samsung SSD firmware upgrades using Samsung Magician
        3) Clone old SSD to new SSD using Samsung Data Migration Tool
        4) Remove original SSD and move new SSD to original slot
        5) Confirm laptop boots using new SSD
        6) Install additional RAM

        • Yeah, your upgrade steps seem fine and the Samsung data migration tool should work, I haven’t tested that tool out so I can’t 100% confirm the required steps.

  • I upgraded the ram and added a 1 TB SSD. I also cloned the operating system from the 512GB SSD to the new 1 TB SSD. I managed to get the bootup sequence to start on the 1 TB drive, but out of concern of it jumping back to the 512 GB SSD, I wiped all the partitions off the 512. Now the system wont boot and throws errors at me. I’ve been trying to do a fresh install of Windows using a USB drive, but the system wont recognize the USB to boot from. I disabled UEFI and secure boot. Still no luck. Any suggestions?

    • Hey Ofer, make sure you change the drive boot order in the computer bios before booting the drive with Windows or with the Windows USB.

      If you believe that your drives are corrupted, your Windows installation usb should be able to wipe both drives.

  • Is there any need to back up Windows before doing the upgrade? I’m leaving the factory SSD in place and duplicating what you have done.

    • If you want to keep your Windows license key, you can put the new SSD in the second slot and use Samsung migration software. After migrating, you can wipe the original SSD and use it as an extra drive.

      If you have an extra Windows Key, you can just perform a fresh install of Windows using a flash drive.

      There are many tutorials online if you need assistance with the process.

  • Dear Jay,

    So the best I can do for the RAM is to add 16G to the empty slot?

    Do you think I can replace the 256G SSD with 1T SSD?

    Thanks for your advice.

    • Yeah, the best you can do is add 16gb ram to the empty slot and you can also definitely replace the 256gb storage with 1 TB.

      However, you need to reinstall Windows using a usb containing the Windows iso file. There are many guides online for it and should be fairly simple.

  • Dear Jay

    My kid has Samsung’s NP940x5j-K02: with 8G RAM (soldered in) plus empty slots; and 256SSD storage. Do you think I can do similar upgrade for it like you did with your 17″ LG?
    I thank you for your advice and suggestions.

    • Yes, a upgrade should work for that laptop as well if a Ram slot is available.

      Upon looking up the processor for your laptop model, the maximum ram capacity per slot is 16GB, the 32GB will most likely not work. Double check to see if your laptop uses sata ssd or nvme for storage upgrade.

  • thanks for this guide. question about the ram module that can be upgraded: does it have to match the type of onboard ram, which is DDR4 2400MHz? the ram module you chose has higher MHz. also, the module you chose is 260 pin SODIMM, 1.2V (i couldn’t find the equivalent information for the ram that comes with the lg gram 17). do any of those differences (MHz and possibly the rest) matter? also, is there a maximum ram size for that slot?

    • Hey TG,

      You do not need to match the MHz, even though the Samsung RAM is 2666 MHz, the laptop will bottleneck the speed of both ram to 2400 MHz. The rule is that you never want to go lower, always higher for MHz.

      SODIMM is the ram module for laptops which are all 260 pins.
      1.2V is also common for DDR4 SODIMM RAM modules.
      (You can do a search for DDR4 SODIMM specs)

      I suppose the maximum ram size for the ram slot is 32 GB as that is the highest RAM module available for sale and it is also recognized by the laptop. This also means any smaller RAM module such as 16GB should also work.

      Let me know if you have any further questions!

      • thanks, good to know. so it sounds like there is no benefit to higher speed (relative to onboard ram speed) and a detriment to lower speed (also relative to onboard ram speed), meaning that matching the speeds exactly makes the most sense.

        also, i found the following info on page 56 of the lg 17 user manual, which says max ram is 16gb – https://www.lg.com/us/support/product/lg-17Z990-R.AAS9U1

        here’s what it says:

        Product Specifications
        System Memory

        DDR4 SODIMM
        The maximum capacity of the main board is 16 GB.
        Memory of 3 GB or more is supported only in a 64-bit O/S.
        Memory size may differ depending on the model. The user must not
        arbitrarily replace the memory.

        • The portion about the 16gb is incorrect, probably to discourage user from opening their laptop. The base model comes with 16GB and they purposely made one of the 8gb swappable lol

          • lol i didn’t see your comment before i posted the one below. i agree it doesn’t make sense for one slot to be swappable and easy to change while stating the max is 16. i don’t see why they would do that – why not solder both to the motherboard or use a single 16 module that’s soldered (if it’s truly16 max) or say in the manual that it’s upgrade-able and the max is X (if it’s truly higher than 16). either it’s a mistake on their part or there’s something else i’m missing.

            maybe they want to make it easy to upgrade because they know it’s what people want but they don’t want to be legally liable if it messes up your laptop because they didn’t test it at higher ram levels?

            or some other reason like it’s simply an error on their part – for example, different departments not communicating properly with each other, which can happen in big companies.

        • all of which begs the question: why make one slot able to be changed if the laptop ships with the maximum ram and they demand (lol) “the user must not arbitrarily replace the memory” (but rationally replacing it is apparently ok haha)? unless it’s able to be changed for the sake of repairs only. hmm…

    • Hey Tim,

      I have not tested the durability after upgrading, and I did not baseline the battery life before adding the NVME or the additional RAM.
      As of right now, the battery life works for my current needs.

  • This is exactly what I am thinking I’ll have to do. I’ve been trying to get full satisfaction from an external thunderbolt NVME, but there seems to be no way to boot from there, and I almost always have a dual or triple boot setup going. Thanks for the post!
