    Hi, so I finally upgraded from a GTX 780M to a GTX 970M. Not much of an upgrade, but with the money tight, it's something, although I did run into some issues.

    BIOS, strangely, doesn't show the GPU, but it is updated. Windows detected it, installed a driver for it, didn't show any errors, obviously it installed an older version and I wanted to update it. But whenever I try it install the ewest version, I get the following error:

    This NVIDIA graphics driver is not compatible with this version of Windows.

    This graphics driver could not find compatible graphics hardware

    Windows version: Windows 10 Home 64bit 21H1 19043.1266 Build

    • I did uninstall old drivers with DDU, disabled automatic driver updates and then deleted drivers again then tried to install newest driver, same thing.
    • I checked a few times, I definitely downloaded the driver for the right Windows version
    • GeForce Experiene shows Unable to download recommended driver
    • Sometimes a different error would show up NVIDIA Graphics Driver Install Failure
    Is there something I can do or is the GPU just broken?

    Sounds like you need to mod the driver as Device ID doesn't match what is in the Nvidia Installer.

    TechPower up as an application that allows you to mod the driver and self signs it too for you but mileage may very NVCleanstall (v1.10.0) Download | TechPowerUp

    Well, it kinda worked, passed that error but while installing I got a BSOD with nvlddmkm.sys and after a restart I got this : https://i.imgur.com/t5RKRMK.png

    The 970m is a nice upgrade, especially if you tweak it, it has lots of headroom.

    Yep the 970m is kind of a marine of MXM GPU's when it comes to overclocking.

    Didn't think about that, but I'm actually afraid to tweak it because I can't get proper readings from it, they're a bit weird. For example, HWinfo64 sometimes shows information, sometimes all values are at zero for the GPU. The manufacturer told me that it's most likely because the BIOS doesn't recognize the card. I was thinking about flashing a custom BIOS, but I can't find any or I'm just bad at Google.

    It would more mean the vbios would have to change.

    Can I use any custom vBIOS for that? I can get svl7's vBIOS for the card.
