My first run (800MHz)
ALU: 3799
FPU: 4186
MT: 20782
Total: 14865
My Second run (3700MHz)
ALU: 6610
FPU: 7193
MT: 21582
Total: 16393
It only increases by 10% when my clock goes from 800 -> 3700 MHz?

Yeah, AMD sux0rs didn't you know that?
Late last week AMD finally got back to me with an answer. The feature that caused the CnQ bug in the original Phenom processor was the processor?s ability to run each core at a different clock speed. A nasty combination of Windows? scheduler and the Phenom?s power management could result in cores, under load, running at 50% of their frequency. AMD fixed the problem by removing the feature; in the Phenom II all cores attempt to run at the same frequency.
When AMD put out its master BIOS code for all 7xx series reference motherboards, the Athlon II did not exist. The fix that was applied to the Phenom II would not be applied to any other Phenom II based derivatives, they would simply get treated as original Phenom processors with varying clock speeds between cores.
And that?s what?s going on. The Athlon II isn?t told to run both of its cores at the same frequency and thus you can have situations where performance is much lower than it should be.
AMD is aware of the issue and are currently working with motherboard vendors to properly enable BIOS support for the Athlon II. Until then, the best way to run and use the Athlon II is with CnQ disabled. Unlike the original Phenom, this bug should get fixed in the near future.

Yeah, it's so hard to resist cracking a joke at a nuclear disaster that caused the deaths of countless innocent people who just minded their daily lives.
Piece of shit. Please, ban me. If scum like you roams this site as a mod I don't want to be associated with it.

If that's not an example of someone who's ridiculously uptight, I don't know what is.
