Nvidia RTX 3070 Drivers for Windows 8.1

Anyone has a modded driver that would install on 8.1? Inf Modding doesn’t allow installing of w7 drivers so im not sure what to do, help appreciated.
My device id : PCI\VEN_10DE&DEV_249D&SUBSYS_13051462

me too

Welcome to the Win-RAID Forum!
Instead of waiting for a modded driver you (and @burzeus ) should try to get the original driver manually installed by using the “Have Disk” option and forcing the installation (don’t forget to set a “Restore Point” before doing that).
If you should succeed, your OS will work with a WHQL certified driver (and not with a modded one).
Good luck!

P.S.: I have deleted the other thread you had started about the same topic.

@Fernando
thank you!

That would not be possible since its only supported on Windows 7 or Windows 10/11, Have Disk simply says couldn’t find drivers.

Please read >this< post, where I have written some more details about how to force the manual installation of a driver, which natively doesn’t support the related device (due to missing DeviceID entry within the *.INF file).

@Fernando my epik emulation skills do not allow me to install it, even testing with a real one, and I believe a .SYS file edit is required

if any other people want to try to do it then do a manual search HERE

It simply doesn’t work, actually its blank when attempting to force the Have Disk Option with any of the INF files and the nvidia installer shows the error in the picture. I think a .sys modification would probably be needed like @Aquavision says. I believe RTX 20 Series didn’t support Windows 8.x aswell but worked unofficially. RTX 30 Series seems to be a no-go :frowning: .

Since I only have modified text files and never a real driver (= *.SYS file), I cannot help.
By the way - any modification of a Copyright protected driver software (a *.SYS file surely belongs to the "software") may be punished by the driver manufacturer.
