bystander :
If you modify the existing bios to unlock the shaders, then use MSI afterburner to overclock it, it is very possible, if not highly likely. I've seen a number of people with that card be successful. DO NOT FLASH a 6970 bios on the card, but you can still unlock the shaders.
Forgive my unprofessional instruction, but it can work for ANY 6950 1gb or 2gb: http://www.tomshardware.com/forum/316974-33-radeon-6950-shader-unlock-instructions#t2368661
Any advise on why I can't get past step 13? I followed all the steps and when I hit enter on step 13 the loading bar for the bios goes about halfway and then just dissapears
also did it in ms-dos
reboot and still have the 1408
my card will not have the shader?
Its exactly the same: (not sure if its supposed to be)
When I boot from usb and use atiflash to flash the stock bios to the modded.bin everything is the same:
