Anyone know why a GTX 770 would simply not work in an X79 motherboard in Windows 10?

I have two different EVGA 770s and I have tried different driver packages (475.14 is the latest), tried DVI and DisplayPort...

With the default Windows 10 drivers from 2020 I was just getting a black screen during startup (not no signal, an actual black screen). Switching to 475.14 (the latest with 770 support) it will crash during the driver install with a garbled screen, and when I reboot the system it will hang with a garbled screen or slowly load a sad face blue screen, where it then hangs indefinitely.

Very odd issue though since it happens with two different cards. I am not familiar with the X79 platform and I haven't used a Kepler based card in Windows 10 in years, so I don't know if there are some hoops I have to jump through to make these work together happily. Any ideas?

BTW, I know this is probably not retro to a lot of people, but none of this 12+ year old hardware is supported by Windows or the manufacturers anymore. If I ask anywhere but VOGONS I'm going to get harassed... 😀

EDIT: Hmm... seems to work if I switch the PCI-E slots to Gen2 in the BIOS? Man... that'd put a damper on my plan to run SLI on this thing...

I am running a 4930K so it should work. Also, a Quadro K2200 (Maxwell based... basically a 4GB GTX 750) works fine without touching PCI-E gen settings.

Googling it I'm not coming up with any reason why an X79 system with a 4930K would not work with a GTX 770 in a Gen3 slot. The motherboard BIOS is fully up to date as well. The board is an ASUS P9X79-E WS.

On a similar note, I'm still trying to understand why I had this issue with a pair of GeForce FX 5500s.

Two FX 5500s but only one works in my 440EX

X79/GTX770/Win10 : should work.
Although I don't have an X79 machine, the GTX770 was fine in X99.
Currently it runs in AM4.
