Overclocking the Memory
As always, overclocking is dependent on quite a number of things. Firstly, a good board is needed with plenty of voltage options. GIGABYTE's P35T-DQ6 fits this bill but there are quite a few others out there like the ASUS P5K3 range of boards which also offer exceptional overclocking features. While we strive to give as good a results as we can, yield rates also play a big part in overclocking results. Some people might get the end of a line, giving very little overclocking; others are lucky to get in the middle, where yields are high and overclocking is supreme.
All we can say is WOW. Over 2000MHz DDR3 speeds reached. We did this on our GIGABYTE board using a 1:2 memory ratio divider and a voltage of 2.1. This was quite high for DDR3 and if you don't have good case air flow, don't even thing about trying for this amount as the modules got quite hot during the process. We didn't have to change any of the memory timings, the modules were quite happy to run 905MHz with their default timings.
Corsair on the other hand was a bit of a disappointment; while able to run its 1800MHz with a timing setup of 7-7-7-20, overclocking turned out to be a big bust. We only managed to get 1855MHz out of it using 2.1v, and this was with the cooler mounted. Lowering timings and adding more voltage still didn't help us here.
Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing. Due to time constraints we weren't able to tweak the motherboard / memory to the maximum for the purpose of finding the highest possible result as this could take days to find properly. We do however spend at least a few hours overclocking 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.
