Overclocking the Athlon II processor was extremely impressive!


We were sent the A2 620 clocked at 2.6 GHz and with little effort, we managed to clock this baby all the way to 3.9 GHz using air cooling. Unfortunately 4 GHz was out of reach as the CPU just wouldn't get up there; however 3.9 GHz out of a 2.6 GHz processor was extremely impressive indeed.


You can see the validation for the CPU here.


As all overclocking results are dependent on the hardware you use your results may vary. Results of our overclocking tests are included in the performance section with the stock scores.


Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing the motherboard. Due to time constraints we weren't able to tweak the motherboard to the absolute maximum and find the highest possible FSB, as this could take days to find properly. We do however spend at least a few hours overclocking every motherboard to try and find the highest possible overclock in that time frame. You may or may not be able to overclock higher if you spend more time tweaking or as new BIOS updates are released. "Burn-in" time might also come into play if you believe in that.
