During my testing I found that while the kit ran flawlessly at its rated speed of 2400MHz, they just did not offer a whole lot of headroom above that, even when pushing 1.75v+ through them. Seeing how running a 125MHz or 166MHz strap is a bit easier on the memory controller, I swapped to the 125MHz divider and started upping the frequency up a little at a time until reaching the maximum clock speed on the HyperX modules. I left the memory sub timings alone and controlled by the board, adjusted the primary timings to 12-13-13-33, adjusted the DRAM voltage to 1.70v, started up again, and finally reached 1260.2MHz or just over 2520MHz for a 120MHz gain in clock speed. That represents about a 5% gain from just testing and tweaking. What I found was that the Kingston HyperX 10th Anniversary modules performed well even with the boosted clock speed. The low profile heat sink makes sure there are no restrictions to the CPU cooling solution used.
