Hello,

I have the above model (Serial Number: NXGNUAA001XXXXXXXXXXXX) and I had purchased a Samsung evo 970 back in the day and had it installed in the second M.2 slot and everything was OK.

Recently, due to the laptop getting older and slower, I noticed that the evo didn't report the speeds it was supposed to, and checked with HWinfo and found out that the second M.2 slot operates at PCI x2 speeds, and not at PCI x4 speeds like the first slot.

So I tried to swap the ssds around and the system (Windows 11 pro) kept hanging on me, when I tried to benchmark it.

I tried uninstalling all drivers, and the Samsung NVME driver, and reinstalling. It is basically the same situation as the one other thread attached below.

That thread had no answer besides "don't do it". Can someone tell me if we can do something about it? And if not, can you let me know the reason (hardware incompatibility, motherboard limitation, bug of the evo 970) that it doesn't work?

My BIOS is on 1.0.9, Windows are fully updated, the system runs fine in the PCI x2 configuration.

I also noticed the evo 970 running a bit too hot when installed in the m1 slot. Maybe something happens there?

it's such a shame that we can't look at the service manuals ourselves. If someone has it and can share, please let me know.

    Hi, the second PCIe M.2 slot in the Acer Swift 3 SF314-52 supports PCIe Gen3 x2 lanes for SSDs. 3X2 means a max of 2GB/s with a Gen3 SSD like the Samsung 970 Evo Plus. The first PCIe slot is 3x4 lanes for Gen3 drives if after swapping the 2 drives the 970 SSD still runs at 2GB/s I suggest trying Samsung Magician program to create the secure erase USB (see link). The 970 Evo Plus is from February 2019, almost 6 years old design, consider getting the latest Gen4 Samsung 990 Evo Plus that runs cooler. Samsung Secure Erase | Puget Systems

    Thanks for answering Puraw!

    After swapping, the system reports at HWinfo that the 970 evo runs at PCI x4 (full speed), but crashes Windows the moment I try to benchmark it.

    Do you think it's a data/format issue and secure erase will fix it? I can give it a try but given it's my daily driver I would like to be sure it's not a hardware issue first. So, you think that what I did should work? placing the 970 ssd at the first x4 slot?

    Notice that it's not even 970 plus, it's the plain 970 EVO (before plus). I know that there are better drives nowadays but I don't want to spend more if it's not going to work due to a motherboard limitation.

    Hi, you mentioned the heat of the 970 Evo so I suggested the new 990 Evo Plus SSD design that will run much cooler, the 970 has DRAMM and has proven to be a very reliable SSD, not sure what Plus entails. Yes, I think that erasing the drive will help the booting problem, I checked other forums on that subject: IMO this is not a HW issue. Backup the data so you won't lose anything, I use W7 BU Image file creator in Control Panel W11 24H2. I don't know if you try to boot from the 970 or from your original boot drive that is now in Slot 2? Did you move that drive (HDD1) to the top of the Boot devices list on the BIOS Boot screen?

    Yes, I tried to boot with only that drive installed and I changed the boot order. I managed to get into Windows without a lot of problems (a couple of automatic repairs), but the problems started after I logged in, and then Windows were crashing (with BSODs) when I tried to benchmark.

    Just some additional advice as I've got extensive experience using the Samsung 970 EVO Plus M.2 SSD drivee.. Your Swift SF314-52 laptop is a 2017 laptop and the Samsung 970 EVO was released in 2019 February, so even if you bought the laptop and the M.2 SSD drive in 2019, and this is especially using this drive as a slave drive, it should be even less of a chance of getting damaged from overheating, as this drive should be working perfectly, as slave M.2 SSDs in the second slot run allot cooler compared to the boot drive

    What I suggest is that you first install the latest version 8.2.0 Samsung Magician then check the 970 EVO read/write speeds and check if the drive has the latest firmware and see what temps this drive runs at through that software, btw I’ve been using the M.2 970 EVO Plus drive for gaming and as a boot drive in different laptops since it was released in 2019 also, I've also used their SATA 3 / 2.5” 850 EVO which was released before 2019 and both work perfectly today in different laptops. with no overheating or loss of data or performance.

    This is the Swift SF314-52 laptop M.2 SSD drive specs from its Acer service guide , note that capacity specs in windows is governed by the drives format and Win-10 has an 8petalyte limit at GUID (GPT) type format

    From my experience with the Samsung 970 EVO Plus, this drive only gets hot to the touch but and usually (depends on the room temp but at at 25C (77F) for an example, and what you use the laptop for) this drive at idle should be running between 35-56C max temps but they do get hotter with gaming, also remember that your Swift SF314-52 which uses the integrated i5-7200H cpu graphics is not a gaming land if used in extreme and gaming/editing purposes, this laptop cpu and M.2 SSDs will get very hot as its a 14" enclosure and cross flow ventilation cooling is limited.

    Below is your Swift 3 SF314-52-557Y thermal cpu/graphics module that has 1x cooling fan, the dedicated gpu ,model has a more intricate thermal module.

    What I suggest that you do as a final solution is this, back up all the valuable data on the 970 EVO drive first, and then clone your oem M.2 SSD boot drive of your Swift SF314-52 onto the Samsung 970 EVO Plus with the Magician > Data Migration doing this clone inside your Swift SF314-52 laptop (at DD1 and SSD2 slots as its 100% quicker than with an external USB-C M.2 SSD case) and then buy some good graphite thermal pads and cover the entire top of the 970 EVO M.2 drive (I’ve done this exact thing and it works) with this type of thermal pad material so that this drive dissipates heat better. Good luck and hope this helps you out further.
