Overclocking the Gulftown was not too difficult; there are a few new things to consider. As you increase the core count you increase the chances of errors between the cores and in cache. This does make it a little bit trickier to get a good 24/7 stable OC.
Thankfully you have more room to play with voltages; even at 1.375 we never peaked over 69c under 100% load (during our HyperPi testing). At the time of this writing we have gotten into Windows at 4.47GHz, but it is far from stable.
You can see the validation for our stable OC at 4.2GHz here.
Of course, if you want to go all out and peg the voltages you can get a lot more than we did with our air cooled rig 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.
