I thought I should add my experience so far with the updated BIOS.

It works great up to 890 GPU clock. After 890 GPU clocks, I start having driver crashes. The good news is the Memory Clock at 1375 has no issues.

3dmark 11 went from 4600 with maxed 6950 clocks, to 5300 with stock 6970 clocks.

I'd also like to mention that when my system did lock up with 900 GPU core, my temps were never above 75C. I assume this may be a voltage issue or something else...anyone care to give me advise if there is something I can do, as temps do not seem to be the issue?
