M17x R4 GPU Upgrade issues

Hi there,

Long story but my GPU died a while back and I'm finally getting round to upgrading.

So after a lot of research, on here and other websites I went for a GTX 970m, a good upgrade from my GTX 675m

So I went ahead and followed the step by step instructions, clean install, A12 unmodified bios etc and all seemed ok, the card shows in bios as Nvidia GPU.

However this is where the problems start.

Card does not show in device manager, only shows as basic display adapter and no matter what I try I cannot get the latest display drivers installed, won't recognise the card during install and quits.

I have tried two clean installs, multiple different drivers and even called Nvidia only to be told to contact my computer's manufacturers.

Any help/tips/suggestions would be greatly appreciated, I'm happy to try anything to see if it helps to be honest.

 

You need modded drivers.

@TheReciever can help you

 

I'm rather unskilled when it comes to modified drivers actually, I understand the process but never seems to correct.

I know you need the device ID from the gpu for starters, then you'll need to add that to the inf, but I'm fuzzy at that point.

@Rengsey R. H. Jr. May be able to help if he's got time, if not there are others here are aware of the process of modding drivers

 

Post your GPU Hardware ID and thy shall be helped.

 

I think it's easier if your running peg mode as you might need to alter another line for the Intel HD if you are running SG mode.

 

I'm

out right now but I will do this as soon as I get home.

Thanks.

Not gonna lie, I have no idea where to even start with this.

ok, so in my hardware id i have the following four lines...


PCI\VEN_10DE&DEV_1618&SUBSYS_05511028&REV_A1
PCI\VEN_10DE&DEV_1618&SUBSYS_05511028
PCI\VEN_10DE&DEV_1618&CC_030000
PCI\VEN_10DE&DEV_1618&CC_0300

This what you need? Any other info then im haapy to provide it!

Thanks very much

You may be right, although I had modded sm 3xx driver versions during last year the usual way I always did for PEG and they all worked for 970/980ms in SG Mode in m17x r4, but not tested that with any 4xx driver yet.

 

Sorry just re-reading this and you mention it worked 970/980ms in the past. I had downloaded a modified driver from the eurocom website and tried that, turned out it was a driver for 980 and didn't work ☹️. Hopefully this doesn't mean that a modified driver for a 970m would also not work?

Thanks again.

 

No, every GPU/Laptop combination needs its own mod-line in the inf-file.
Here's my (very basic) mod for driver 430.86.

Am using this method of modding ever since, to date it worked on all combinations I had to deal with, about 10-15 combinations (of m17xs and m18xs).


Removing the old driver with "DDU" in Safe Mode and Win "Test Mode" activated, that should be clear to you (??).

Also copying the folder "C:\\NVIDIA" to your Desktop, as soon as the error message appears (don't click it away until you've done so as the folder will disappear), then replacing the inf-file, and start the modded installation.


Take this driver 430.86: https://www.nvidia.de/Download/driverResults.aspx/148087/en

Hope it works for you.

 

Amazing, I will give this a shot as soon as I get WiFi and can download the driver.

I'm good with the safe mode bit test mode? Is it activated the same way as safe mode? If not I'm sure I can find something on Google no problem

Very much appreciate the help thanks again and fingers crossed.

Misspelling of mine in the last post, correct phrase is: Disabling Driver Signature...

 

Tried and working!!

Cannot thank you enough for your help!

Nice to hear
