NVIDIA GT 650M Benchmarks

[lh6kean]

Hello coolguy!

"NVMI.inf is found in C:\Program Files\NVIDIA Corporation\Installer*\Display.Driver.*\
(the stars are numbers) open the folders with the highest number.
The naming convention of this file is NV**.inf (the stars are capital letters) this
is the only file named with four capital letters in that folder
(in the MSI graphic drivers there are only one NV**.inf file but in NVIDIAs official
drivers there are several such files).
This means that NVMI.inf might have a different name on your system."

Refers to finding the OEM INF from manufacturer supplied drivers. Maybe I did not specify that well enough...

I wrote a more general guide. Do you think that this is better coolguy? I ask you as you seem to know something on the topic.


How to mod *.inf file of NVIDIA official drivers to install on a system with a NVIDIA GPU


1. Download and unpack the official drivers to be modified.

2. With OEM drivers installed go to
C:\Program Files\NVIDIA Corporation\Installer*\Display.Driver.*\
(the stars are numbers) open the folder with the highest number. Search for a file
named NV**.inf (the stars are capital letters) this is the only file named with four
capital letters in that folder. Open it in notepad.

2. In the folder of the unpacked official drivers search for and open the file with the
same name as the one found in 2. Open it in notepad.

3. Open Device Manager, go to Display adapters, double-click your NVIDIA GPU, go to
Details, under Property choose Hardware Ids, copy the second value
(e. g. PCI\VEN_10DE&DEV_0FD1&SUBSYS_10C71462)

4. In the NV**.inf from the OEM drivers go to section
[NVIDIA_SetA_Devices.NTamd64.6.0]
find the line that contains the string copied in 3., copy this entire line.

5. In the NV**.inf from the official drivers go to section
[NVIDIA_SetA_Devices.NTamd64.6.0]
paste the line copied in 4.

6. Repeat 5. for all [NVIDIA_SetA_Devices.NTamd64.6.*] sections

7. In the NV**.inf from the OEM drivers go to section
[Strings]
copy the lines that list your GPU

8. In the NV**.inf from the official drivers go to section
[Strings]
paste the lines copied in 7.

9. Run setup.exe

lh6kean, you need to make sure that the settings in the sections for your GPU matches with the ones in the OEM provided INF.

If you are doing it right, then it's good. You can ask me if you need any help. I have been modding the INF's for 2 years. The section numbers are not the same in all the INF's.

So I did all of this as best as I could and when I tried to download the 304 beta, it still did not let me download it :/
I think I may have gotten confused somewhere when I was copying and pasting. This INF stuff is nuts. I don't how you guys do it.

coolguy, what your saying is that I'm missing something important and it's not enough to only modify the [NVIDIA_SetA_Devices.NTamd64.6.*] and [Strings] sections?
In Device Manager I found an interesting Property called Inf section with a Value that matches a section in the .inf. Do you mean that all values in that section must match between the OEM drivers and the new drivers and that is what is missing?

Thanks!


xmikewest as coolguy wrote in the post above yours something might be missing in the guide that I wrote. If you by download mean install and the error you got is something like compatible hardware not found then I hope that I can update the guide so that it works for you to. BTW what hardware do you have?

Yes I meant install. When I tried to install the 304 beta, I did get an error that would not let me continue with the install.
My hardware is :
• Windows 7 Home Premium 64-bit
• 3rd generation Intel(R) Core(TM) i7-3610QM Processor (2.3 GHz, 6MB L3 Cache)
• NVIDIA(R) GeForce(R) GT 650M Graphics with 2GB GDDR5 memory [HDMI, VGA]
• 8GB DDR3 System Memory (2 Dimm)
• 750GB 5400 rpm Hard Drive
• 17.3-inch diagonal HD BrightView LED-backlit Display (1600 x 900)
Thanks.
This is an HP notebook.

By the way Cakefish, where did you buy your laptop from (Samsung 550p5c-so3uk?) as all the places I am looking state that it has 3xUSB 2.0 rather than two 2.0 and two 3.0.

I see some 650M's in the 304.48 driver nvhm INF, so your GPU might be already supported.

Yes, the the lines in the section should have the same settings.

[Section002]
AddReg = nv_DRS_addreg
AddReg = nv_FTS_addreg
AddReg = nv_commonBase_addreg
AddReg = nv_commonDisplayModes_addreg__02
AddReg = nv_controlPanel_addreg
AddReg = nv_global_addreg
AddReg = nv_miscBase_addreg__01
......

For example from the line "AddReg = nv_miscBase_addreg__01", when you go to that miscbase section, it should have the same settings as in the OEM INF. From the 304.48 driver, Nvidia started combining the Vista, Win 7 and Win 8 INF's. So, there should be 3 sections for each GPU.

The section numbers in your OEM INF and the ones in the Nvidia released INF are not always the same. You need to make sure you use the right sections meant for your GPU.

[lh6kean]

coolguy, that sure makes it a lot more complicated than I first thought. Hmm...

I will take a look at it tomorrow and see if I can solve the problem.
