Hi, I haven't tried nvflash yet, but I discovered that Gigabyte has a tool called vga@bios which was able to backup my BIOS for the my GB 780 Windforce OC. Worth checking.

It uses nvflash 5.138 -v to get info on the board. Just tried it and it works. Are you able to -v with it? (dos window administrator mode)

I used a "spare" EVGA 780. Had the same error on bios backup in nvflash.

So i again used GPUz 0.6.6 to dump the stock bios.

Then i flashed with the techinferno bios through windows nvflash. Worked perfect.

I flashed the stock bios back, still works.

After that testing, i did my own Gigabyte 780, flashed fine to techinferno. Im going to assume the backup will also be fine from the above testing i did.

My ASIC is 71%. For stable gaming my final offest was +195/195, for Core of 1187Mhz constant

Anyone running SB-E CPUs?

Just got mine, hit +200Mhz Core/Memory with stock volts, now trying to flash it.

Trying to save and flash my reference Gigabyte 780 Bios, using latest nvflash from techpowerup.

Turned write protect off with nvflash.

Upon running --save backup.rom I get the "ERROR: PCI Block chain corrupted - PCI Expansion ROM Header not found - GetUEFISupport() failed" in Windows or DOS.

I can backup the Bios through GPUz 0.6.6 but not sure if it is actually correct...

Any ideas to whats the problem?
