Overclocking was performed on our GIGABYTE P35T-DQ6 motherboard. Now, some might be asking why we go with the older P35 chipset and not the X38. The simple reason is that we can't manage to get as high an FSB out of the X38 as with the P35 due to the X38's higher heat generation. It is slightly more unstable at high clock speeds.
We used the 1:2 memory ratio to prevent the CPU being the limiting factor, and since the FSB is half that of the memory speed we can get the RAM up pretty high. While the modules are rated to do 1866MHz or 933MHz actual clock, we couldn't quite get there in the time we had. However, we did manage to get 901MHz out of the modules, which is extremely impressive nonetheless. With more tweaking and time we are pretty sure these modules will kick well over into the 2000MHz range.
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.
