I just reran at 4.3GHz and actually got through without the CPU throttling back.
So I uploaded the result, then clicked reset in MSI afterburner only to discover that it didn't reset the clocks or volts, only the fan speed. Windows crashed.
So I rebooted and opened Futuremark ORB, and it won't make this result public either:
24,491 | Apokalipse | Phenom II 1090T @ 4.3GHz | HD5870 @ 1100/1280 | W7 x64 | ORB - can't make public
At least CPU-Z validation is working:
Now if I could just get the multiplier to go higher than 20x using XP
In XP I get a CPU score of ~7500 at just 4GHz.
GPU scores are lower in XP, but overall score is better (at same clocks)
