Help: Force flash vBIOS with nvflash - win/DOS (Solved-ish)

[the54thvoid]

Is there not an issue with the Plex chip (if it uses one) being recognised as an actual graphics adapter? I know that caused issues on some motherboards that used the chips to create more PCI-e lanes.
Probably utterly unrelated but it's all I know that could pose problems.

Was what I thought too, but even on a board without PLX it was a problem. What did end up working was flashing the same vBIOS back onto both ASICs, but keeping the later retail vBOIS on the PLX bridge. For some reason that's all it took to get the card working, though only with older drivers.

@Law-II
Gave the HEX edit a try but could not locate the offset storing the board ID in the firmware. The offset it was supposed to be in was instead storing VRAM timing information, and the whole vBIOS became scrambled when edited. The fourth reflash of the old firmware appears to have worked....

Here's some 3DMark because why not:

Same issue here with EVGA GTX980Ti Classified that shows as a reference card. No way to get this to work. Works fine on my other 4998 card but not on the 4997 card.

You need a modified nvflash version to fix that error, here:

NVIDIA NVFlash with Board Id Mismatch Disabled v5.590.0 Download

This is a patched version of NVIDIA's NVFlash. On Turing cards, NVFlash no longer allows overriding of the "board ID mismatch" message through comm
