Bought an 870m (MXM) to upgrade from the 660m in my Clevo P151EM.
Obviously as it's a GPU upgrade I'll need to modify the appropriate inf from the latest Nvidia drivers.
I tried following the guide here, but Windows crashes/freezes when I reboot (after installing the drivers, driver signature check disabled) for a few seconds, and then disabling the 870m with code 43.
To fix this I used J95's instructions for Balamut, to no effect (with these instructions the installer doesn't detect the 870m).
As the machine is a Clevo I need to edit 'nvaci.inf', which doesn't include the device/hardware IDs for my GPU (which is a good sign, I guess).
I used the following in '[NVIDIA_Devices.NTamd64.10.0...14310]':
%NVIDIA_DEV.1199.5105.1558% = Section086, PCI\VEN_10DE&DEV_1D10&SUBSYS_51051558
In '[Strings]':
NVIDIA_DEV.1199.5105.1558 = "NVIDIA GeForce GTX 870m"
...which matches up to my GPU (screenshot attached)
The Nvidia installer doesn't detect my GPU with that, I've had some success messing-about with inserting the GPU into the various infs, all end with the same code 43 error.
Am I doing something wrong here, or perhaps something that I'm completely overlooking?
