Can't install drivers for GTX 970M on a P177SM

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

 

Did something differently this time and now it worked. Thank you so much!

 

no problem.

 

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.

 

It would be worth a shot.

 

Flashed svl7's vBIOS. As I used the OC edition, even the performance improved a little bit, but I don't know, readings still seem a bit off. Before, my GTX 780M would heat up to about 80-85 celsius, even with dust cleaned out and new paste applied, but 970M, after some load, goes up to 77 celsius, and even then that's on the GPU hot spot, as per HWinfo, MSI Afterburner shows 62 celsius max. I know 970M has lower TDP, but would it really make such a difference? And as for overclocking, I don't think it's really worth it, CPU (it's 4700MQ) already seems to be bottlenecking it a bit, during Unigine Heaven GPU usage sometimes jumps around 70-80% and there are times when all CPU cores go up to 100%.

 

The 970M does run WAY cooler than the 780M yes. Even the 980M did.
