Been running a 6990 + 6950 (flashed to full 6970: clocks, volts, shaders) for a while without issue. Switched on PC today to have a blast of Mass Effect 3, get as far as the menu screen and PC hard locks. Proper looping sound instadeath lockup.
Tried BF3, same thing - map loaded, PC hard locked while showing the flashing cursor in the bottom right.
Wiped the ATI drivers fully and upgraded to latest ones (12.2). No difference.
Removed both cards and reinstalled the 6950 in the top slot where the 6990 was. Seemed to get a little bit further doing this but that could just be a fluke as it didn't always lockup instantly on the menu, but it would within seconds. Got as far as loading a save, walked about 5 steps, screen goes black - hard locked.
Switched back to vanilla 6950 BIOS using the dipswitch, card now running at whatever 6950s run at as standard (810 core?). Load game, walk about 5 steps, black screen, hard lock.
As I type this I've removed the 6950 card from the PC completely and am using just the 6990 card back in the top slot. Booted Mass Effect and ran about for a bit with no locking up.
So, card seems to be dead... anyone else think I've missed anything obvious? It doesn't artifact or show signs that it's about to crash, and it was working perfectly yesterday. In the space of a few hours it's gone from playing several hour long sessions of games to not being able to run a game for more than a few seconds at 3D clocks before hard locking.
It seems to work ok on the desktop (2D) if that counts for anything.
Thoughts?
