Use -f switch to force flash.
It's a bitch to fix if you mess up.
Thanks, I will try this out.
Maybe you stop trying ... you can brick the GPU by flashing bios from another brand
The reason is XFX's bios has some high voltage offsets. It's at 0.9375v compared to 0.8875v for MSI/Asus and uses 25% more power when compared at gpuz at same settings.
Since they are all reference cards, I'm trying to force a lower voltage by using another brand's bios.
