Congrats! I have just flashed mine too, well one of them I'm going to flash the 2nd one as we speak. Here is a benchmark that I have done using Mafia 2's built in bench:

Max settings physx off 2560 x 1600:


Non-flashed bechmarks

33.6fps at 800/1250



FLASHED BENCHMARKS

34.8fps at800/1250

35.9fps flashed 800/1375

38.0fps at880/1375


To get those figures, I first benched using the unlocked sapphire 6950, then popped in my 2nd stock sapphire 6950. Before I cannot overclock pass 840/1325 due to the CCC limit now I can reach 930/1400 but it crashed in the middle of the benchmark, so more testing is required to test the card's limit but I'm really happy. The improvement is 9% going from stock 6950 to unlocked 6950 @ 6970 clocks!!! =D

It seems like a lot of people are stable unlocked. Yields must be good. In Unigine I get artifacts here and there unlocked, in games so far I haven't really noticed any. I'm still going to go ahead and buy a real 6970, since my unlock doesn't appear to be totally stable.

Have you used 20% powerboost?

That's a shame, it seems most are getting great results, no need to waste money on the 6970 - put the savings towards a second 6950 down the line and CF 6970 preformance levels.

Raising the voltage in msi afterburner may help remedy this problem

I don't think you can do that for the 69xx series yet.
