Completely Stumped - Need 780 BIOS / NVflash Expert please! - Page 2

How did you flash the BIOS?

First off you find the BIOS that is compatible with your card, hence why I asked which revision.


80.80.21.XX.XX
80.10.3A.XX.XX
80.10.37.XX.XX
80.10.36.XX.XX

There are various revisions of the card, so most likely you probably flashed the wrong BIOS (they are not all created equal). With 80.80 of course being B1 revision. (it should show on GPU-Z and on the die of the chip what revision but 80.80 is a clear give away).

When using NVFlash use the following commands in cmd:

nvflash --protectoff
nvflash -4 -5 -6 (name of rom).rom


I would try again but this time try to flash it to stock BIOS.

EVGA is very cool about the RMA i will get my future card from them

you can always try this :
Find the eeprom chip remove it
flash the eeprom with eeprom programmer
or install a new empty eeprom
here a GTX 780 EEPROM :

I can't really do that or they won't accept the return. I will accept that it's dead.

not all 80.80 are B1, as you can see here - http://gyazo.com/9f95c0a0e200b86efb5716e447ff947b

They are using an old version of GPU-Z, latest version is 0.7.7. It wasnt till around 0.7.5 that they fixed B1s showing up as A1s.

I personally woudn't flash it, but hey its not my card biggrin.gif

Upgraded GPUz to see whats up with the 80.80 with A1 on my card, and same thing...

This card has already been successfully flashed many times with 3A bios, thats whats weird.

http://gyazo.com/47b15d545b46a1dd06a9a340c03bed92

Its not a matter of whether or not I want to flash it now, its a matter of WHY is this showing like this now... has me intrigued.

Not sure if this applies to the OP's problem, but since he is already accepting it is dead it wouldn't hurt to try and bake it, would it? Not sure what baking does/how it helps the card, but I think it has been known to bring dead video cards back to life somehow. Anyone got any more ideas?

baking in 400°c will bake the RMA
