I tried overclocking this cpu for some time now and everything works great, score scales nicely with frequency and on air i reached 4.24ghz, but only a score of 185, my 4.05 ghz result is 180 points. I installed windows with a custom iso with every function not needed for cinebench r15 removed, i also tried a not modified windows, but scores were a few percent lower and a lot less consitend due to changing background tasks. I compared to my other 4 different athlon x2 and x4 and all score about the same per core and frequency. So why are my results a lot worse then this score (yosarianilives - Athlon II X2 280 @ 4064.1MHz - 203 cb Cinebench - R15) even if i reach better clocks?
