Well, I have been playing with my overclocks all morning. Before this morning, I was running at 2.7GHz on my X2 4400+, and it scored a 5.1. The overall score was held back by my memory, which was a 4.5 running at about DDR500. So today i tried upping the memory, and it still gets a 4.5.
So, I think that the ratings are locked at a certain highest score for different types of hardware.... I can't prove thqat, but if anyone else has similar hardware with higher scores, let me know. For comparo, I had a 5.2 overall in Beta 2 with the same setup.
Another thing to note, is that my CPU score hasn't budged a bit. I scored 5.1 (on the CPU) @2.7GHz and right now it's at 2.4 GHz... and yes, I did "Update my score".
My old sig didn't match the new board. Therefore, you get to read this text sig.
