While keeping the stock timings of 4-4-4-12 on the Mushkin 4GB XP2-6400 set of RAM, I wanted to see just how far I could push it. After trying multiple frequencies, the highest I could get the RAM was DDR2 888 (444MHz). I knew that if I loosened up the timings, I could go much higher. I loosened the timings to 5-5-5-12 and got the RAM all the way up to DDR2 1086 (543MHz) before I hit a wall. The HP2-6400 4GB set got all the way up to DDR2 1072 (536MHz) at 5-4-4-12 latencies, which is stock, so it'll be a good comparison to use against the slightly higher XP2 frequency.
CPU-Z: 444MHz at 4-4-4-12 and 543 MHz at 5-5-5-12 latencies.
PcMark05: As in the previous PCMark05 tests, higher is better.
Sisoft Sandra XI: In all of these tests, except for Memory Latency, higher is better.
The XP2 set does much better than the HP2 set in almost all of the benchmarks.
