yeah i get that.... it's just a driver bug....
anyway if people's 6950 are breaking after flashing it's either they using the 6970 bios or pumping way to much voltage though it or letting it get to hot or driver bugs or they don't know what they doing....
my 6950 has been perfectly fine...
in ati CCC keep the clocks at defaults then close it then just use amd gpu tool to clock the card, once you've clocked it you can close amd gpu tool....
don't try using CCC overdrive and amd gpu tool at the same time..
