well this kinda sucks.. should I rma it or is there not much of a difference between the 6970 and 6950? how do i check if it cant be unlocked for sure
I"m not sure, but there is definitely something odd about your card. Whether it unlocks or not there is one variable that shouldn't change and for some strange reason on your card it has. 1 bios is a fail safe and can't be overwritten and one can/should be writable to. That variable is different on your unique card because according to your testing neither of the 2 bioses is writable. That's either a hardware issue or user error. If you satisfied that you have done enough to rule out the latter I'd RMA it. There is absolutely no reason at all why at least one of the 2 bioses shouldn't overwrite.
