Nvidia driver inf modding

[kenny27]

Can anyone shed some light on how to inf mod nvidias lastest drivers?

 

I am trying to get 511.79 work for my m18x r2 and gtx 1080. The nvdmi.inf for dell/alienware is not in the driver fold so i tried modding the next closest one: nvd... something-something which looked right based on the 1028 vendor code in the file.

 

I run DDU and disable signature driver on startup, the installer runs but fails right at the end with message saying incompatible hardware and version of windows.

Try the nvdmig.inf, it worked for me

Post your Hardware ID from device manager and I'll write the line you need to insert.

 

Also, a trap for some people is that the .inf will contain two separate lists of ID's. Each list is for the different compatible OS and as the newest drivers are for Win10 and Win11 there will be the first long list of ID's and then if you scroll further down the list will start again. Put your modded line in each group so you are covered for your OS.

Also don't forget to add your String at the bottom of the .inf or it won't work.

That did the trick!

So the other thing to check is that there maybe multiple inf files for a vendor/manufacturer

There used to be a long guide (for AW, I think) for modding this. I'm gonna have to get back here when I update my old laptop.

Does anyone know how to disable "Error Correction Code" (ECC) in nvidia control panel or by regedit or using CUDA sdk or has this been mitigated by nvidia?

The ECC is enabled on my quadro P4000 and I've read it takes 10% off of the performance of the card. My nvidia control panel has no option for workstation in settings and that is where it is supposed to be to enable or disable it

it also depends if you're trying to run the GPU in SG mode or PEG mode, since 10 series have to be used in SG you have to mod the general inf that includes the optimus functions. to my knowledge (i might be wrong) but the vendor specific ones probably have varying degrees of Mux/PEG specific settings which doesnt include SG, like with nvdmi.inf only being used for PEG mode with the r2 and r1 (i had to mod this one on my r1 for the 780m since it was running PEG directly to the screen)

For anyone else that needs INF mod, I had made a video on how to do it.

Apologies in advance for bumping an old thread. I came across this post, after some searching and seeing the notebookreview forum was shutdown. I've got an Alienware M17X R4 with a Clevo GTX 970M I installed a few years ago. My issue is that I'm trying to get the newest set of drivers to install correctly, and they keep failing. The most common message is "driver is not compatible with this version of Windows" and "This graphics driver could not find compatible graphics hardware". I noticed Nvidia changed the nvdmi.inf to nvdmig in the newest set, and it looks pretty much identical aside from the name change. I've got the hardware ID (that I already made for use with each update up until now), so it doesn't seem to be working. Is there something I'm doing wrong, or is there like an additional step/something else that needs to be done for it to actually install without a hitch? I can post my hardware ID, along with the version I have already made to see if there are any errors/discrepancies. 

Attached is the Hardware ID from the laptop, and this is the ID I have saved for inserting into the .inf; 

%NVIDIA_DEV.13D8.0551.1028% = Section018, PCI\VEN_13D8&DEV_13D8&SUBSYS_05511028

Any help would be appreciated!

I replied to your DM before taking a look at this. Looks like your ID line is right.

 

You also have to add the String at the bottom of the inf

 

NVIDIA_DEV.13D8.0551.1028 = "NVIDIA GeForce GTX 970M"

 

The other two major reasons for your error are;

 

1. Not disabling Driver Signature Enforcement directly before trying to run the installer

 

2. Not inserting your ID line into the correct Operating System group in the .inf.

     - The newest drivers have Windows 10 and 11 support so there are two lists of ID's in the .inf. Place your ID line into both lists so you know your OS is covered. If you find the first list then put your ID line into it and then scroll down and you'll find that the list will start again so you have to add it to this list as well. 

 

EDIT: The line above isn't right, didn't see it the first time

 

%NVIDIA_DEV.13D8.0551.1028% = Section018, PCI\VEN_13D8&DEV_13D8&SUBSYS_05511028

 

You added 13D8 where it should have stayed as 10DE (before &DEV_)

 

It should read

 

%NVIDIA_DEV.13D8.0551.1028% = Section018, PCI\VEN_10DE&DEV_13D8&SUBSYS_05511028

I'm new here. Don't mean to bring up an old thread , but my problem is almost identical. The forum that talked about the GPU upgrade on Precisions is gone, and can't find cache pages either. So I'm starting from scratch.

 

I have a Dell Precision 7530. Bought an RTX3000 gpu and went through all the inf mod. The nvidia driver fails to install giving the same warning as the OP.

 

I've no idea what else to try at this point, and I'm about to send the unit back to the seller, but I want to give this another try. Can anyone give some tips?

 

I have attached the nvdmiwi.inf file if anyone wants to check it. Seems to be the right inf file,  but not sure. I already edited it.

 

I did disable driver signature enforcement and used tried old and new drivers.

 

Any help would be much much appreciated!

I suggest the best way to mod your inf files is to use a tool NVCLEANINSTALL not only does it allow you to download drivers directly for modding but it also allows you to add Device ID's and then signs the driver after meaning no more requiring to disable Driver enforcement.

 

At the same time it allows you to remove the bloat of the Nvidia drivers too.

Thank you thank you! I'm downloading it and will report back if I have issues or if it works. Much appreciated!

Alright! It did work! You saved me hours or days. Much appreciated again!

I have a RTX 3060Ti and my device id is not listed in NVCLEAN so I can't use it. Needed to modify 472.12 standard driver to include this id. My card Id is PCI\VEN_10DE&DEV_2414 

 

If you open newer drivers it includes the needed id. You must select a template and if your id isn't there... This makes it pretty much useless to add new hardware to inf

Any help please?

I think it doesn't really matter which template you choose, at least that's the case with my GTX 1070 mobile. I just took the standard template for the 1070 mobile and it worked fine without even having the same hardware id

 It matters.. as soon as you put in device id and hit next you get an error saying device id doesn't match. Specifically: no valid device id.

what is the purpose of modding a newer driver via INF MOD.??? my gpu doesnt get drivers anymore.

Well, you can mod a newer driver for an older unsupported GPU to bypass a driver version restriction that a certain game may have.

But, the main reason driver modding is just to get newer Nvidia MXM GPU's to work on older laptops.

Kepler still gets updates on desktop. I mod inf to allow my mobile kepler gpus to have latest drivers

i see . but what about in the performance side theres no improvement or there is.?
