Clevo P175EM GPU upgrade from GTX670M to GTX 980M

[Oliver Kasimov]

I just bought a new GTX 980M from ebay, and finish the replacement of GPU. now i face the driver issue.

I can't drive the GTX 980M, it show that the hardware can't work ... 

My HW ID is 

PCI\VEN_10DE&DEV_13D7&SUBSYS_71021558&REV_A1

PCI\VEN_10DE&DEV_13D7&SUBSYS_71021558
PCI\VEN_10DE&DEV_13D7&CC_030000
PCI\VEN_10DE&DEV_13D7&CC_0300
 

and my Nvidia  driver verson is 

391.35-notebook-win10-64bit-international-whql

 

any one who can give me an instruction how to do it ?

 

also My BIOS of P175 EM is the initial one , is it the problems why i can not upgrade the GPU.

Might be a BIOS problem, on my MSI GT70 with GTX680M upgrades to 8.xx, 9.xx and 10.xx cards do require a modified BIOS.

In spite of using modified INF and disabling driver signatures?
