Analyzing the results of our testing, it turns out that nearly all memory kits were able to reach standard DDR2-800 speeds, the only major exceptions being the OCZ PC2-5400 and Mushkin XP2-5300. It is also interesting to see the substantial alignment of the maximum frequencies of the Cellshock PC2-6400, Mushkin XP2-6400, and Geil PC2-5400. This is almost no doubt a result of the fact that all of those modules use the Micron D9 GMH chip.

The proposals from Team Group turned out to reach the highest frequencies out of all modules we tested. The Team Group modules, which are also based on the Micron D9-GMH, not only lived up to the memory chips’ reputation, but went beyond the performance expectations. After seeing the alignment of the Cellshock PC2-6400 kit, Mushkin XP2-6400 kit, and Geil PC2-5400, we expected the Team Group proposals to offer similar frequencies to those modules since they are all based on the Micron D9. However, they ended up providing even higher frequencies.

Analyzing the percent of increase compared to the default frequency, the Team Group DDR2-667 had the largest overclock, reaching speeds of DDR2-1150. The memory was able to run 69.7% faster than its rated limited, clearly illustrating its impressive overclocking headroom. Having the smallest overclocking capacity, both OCZ memory kits found their way to the bottom of the chart. The Geil PC2-5400 also underwent a large gain in frequency, ending up having a 54.6% overclock compared to default timings. It is important to note that most of the memory kits that had the largest increases in frequency also had the lowest rated default speeds.
