NVIDIA GeForce RTX error code 43 on Windows 10 version 1607

[erpdude8]

speaking of 1607, 1607 LTSB 2016 is now in "extended" support as mainstream support for LTSB 2016 ended mid-October 2021.

I updated to 512.78.

 

The DCH display driver package contains NVIDIA Control Panel application. To launch DCH version of NVIDIA Control Panel for the first time, Internet connection is required, and WU, Windows License Manager Service, and Microsoft Account Sign-in Assistant should be enabled.

 

I don't know how to install standard NVIDIA Control Panel and Container along with DCH display driver. The standard NVIDIA Control Panel is still compatible with DCH driver, so users of non-DCH driver can launch standard NVIDIA Control Panel from Windows Control Panel.

Which hex should be edited for a 3070 on 1709?

[halohalo]

If you want to install DCH driver on 1709, just modify the INF file.

[hans_glans]

No, it goes back to the initial problem in this thread.

3070 is only supported from 1803 onwards, irrespective of the driver.

I'm just wondering which hex value in nvlddmkm.sys has to be adjusted after modifying the INF file.

[halohalo]

You have to debug the graphics driver and find out your answer. All I can say is that it is not as difficult as you think.

[hans_glans]

But basically it is:
- install driver with modified INF (-> error 43)
- change respective OS hex value in nvlddmkm.sys
correct?

[hans_glans]

I think I got it but can't try myself. Just tell me if its correct please:

For 472.12, we know the supported version is 17134 which is "42EE" in hex.

After removing the OS requirement from the INF file and installing the resigned driver and getting error 43,

we copy nvlddmkm.sys from the folder, and instead of "42EE" we put "3FAB" (16299), put the file back in and (possibly with test-signing and disabled integrity check) reboot.

Correct?

Unlike 20 series and 16 series, you've proved that 30 series require version 1803 instead of 1709.

 

By starting kernel mode debugging, you can find the hex value and create your solution.

[hans_glans]

With WinDbg or IDA?

Is checking the highest winver in the INF file and replacing it's hex value in the sys file with one version earlier the correct approach?

[halohalo]

Just use WinDbg.

this would work on 8.1 regarding the rtx 3000 series situation?

[halohalo]

OS and driver are different, so the solution will be different.

[hans_glans]

Yes, highly depends unfortunately.

Is there any way to not have testmode on?
