Problem editing GPU bios with RBE - "Invalid file specified" error

[FLoods7]

I used numerious different ways to extract my bios (winflash, gpu-z) but all of them lead to the RBE message "Invalid file specified. Not an ATI BIOS? - Debug information: 'CheckValid' reported error."

I really need to modify my bios becasue the damn factory voltage settings are too low and it causes screen flickering and tearing. Anyways what should I do to get RBE to load my bios?

I am running a Sapphire 7850 2gb

Maybe try loading a stock Sapphire 7850 BIOS file off the Techpower-up site's library?
