I need help modifying the BIOs on my XFX HD 7970 Core Edition as i want a higher Core voltage on my card to be able to OC further (1.35-1.4v). My cards does indeed have dual BIOs. I have a little experience with flashing but not much as a few months back i had a HD 6950 2GB that i flashed with a HD 6970 BIOs but that was it. Any help would be greatly appreciated :)

Hi

Have looked here to see if this is possible

assuming @ 1.3v [manufactures limit] keep an eye on VRM temps with GPU-Z [are sure VRM's are of high quality if pushing for 1.35-1.4v] (most likely 1.4v will damage or degrade the GPU; may be good for a suicide run)

atb (all the best)

Law-II

@1.3v VRM Temps never exceed 40c and core never exceeds 48c

Follow the instructions in the link that Law-II provided.

To flash new bios to the card.

Make bootable USB
Put ATiFlash on it.
Boot from the usb.
Flash the bios: C:\atiflash -f -p 0 biosname.rom

0 = whatever slot the card is in. If it's in the 1st PCI-E slot, it is 0.
