Overclocking
Overclocking of each product was performed in the bios rather than with windows software. As the HTT speed is being raised in order to overclock the memory this results in performance which is not directly comparable with the stock scores from earlier in the article.
Starting with the OCZ ReaperX modules we moved the voltage to 2.2v which is the maximum supported under warranty and began raising the speed at default timings. At these settings we were able to reach 862MHz. Next we loosened the timings to 5-5-5-15 and attempted to boot at DDR2-1066. We encountered no problems and so then tried to find the maximum speed at these timings; the result was DDR2-1100.
For Kingston overclocking we ran a quick check to find out if the modules would boot at the near industry standard of DDR2-800 with 4-4-4-12, this posed no problems. We then returned to 5-5-5-15 and began raising the speed to find the maximum stable speed. The result was DDR2-1168, just over 100MHz above stock settings.

When both sets of modules are overclocked the performance is very close during gaming. The higher speed of the Kingston sticks makes them faster overall but the OCZ ReaperX is never more than two frames per second behind.
