Maximum stable overclock, using 1.30v max in afterburner and 100% fan speed.

Tested using atitool. I found when there's no OC programs running in background it allows gpu usage to go up to 98-100%. It finds errors quite quickly, more than gputool i think.

ATITool running for 22 minutes




ATITool stopped




3DMark 11




Vantage




Crysis




Heaven




I let heaven loop before starting the benchmark, nice minimum FPS

1020MHz on the core artifacts pretty much straight away in ATITool, but it can run benchmarks.
