Overclocking the processor we were able to reach 2.9GHz but it was not stable at that speed however 2.7GHz proved stable, a 400MHz overclock over the core speed. Overclocking using the bus brought in worst results and a core speed of only 2.5GHz so an improvement but not a major one. Compared to the average QX6600 from Intel, they are still better overclockers over AMD even with locked multipliers. We also wanted to investigate how high we could clock just two cores thanks to AMD's Overdrive software we were able to manage each one individually. We clocked the third and fourth cores to the slowest speed possible, 1GHz, and set the first and second core to 3GHz while slightly increasing the voltage. We were able to hit this but unfortunately it was not stable. Neither was 2.9GHz but 2.8GHz with the two cores it brought a stable overclock. Since this is just 100MHz over our stable overclock using all four cores it certainly doesn't seem to be worth it to lower the third and fourth cores to try and get more gains in the first and second but we'll try this again with newer revisions of Phenom and as the AMD Overdrive software matures.
