Well I used RBE to mod my BIOS and unlock the shaders. Flashed with ATIWinflash and all seemed fine,opened GPU-Z and it showed 1536 shader count. But as soon as I try to play a game it locks up flashes to black screen then back to the game that's locked up. Is there anything to do? Reflash,remod BIOS or did I just get unlucky? Seems like most everybody has had no problems with just unlocking the shaders.
