I'm having an odd problem with my 6950 after I flashed the bios to a 6970. The flash worked successfully, but now whenever I try to overclock and run GUIMiner I get increasing amounts of display freezing and driver failure. I think it may be an issue that lays between two programs - AMD Overdrive, and Sapphire TriXX. I disabled AMD overdrive, though the mining hardware spreadsheet on the wiki says I should have the card at +20%. It helped to reduce the crashes a little bit, but not enough.
Has anyone else had this problem? If so, how did you solve the issue of the display drivers failing every minute or so?
Thanks for your input in advance
