For memory reviews we used synthetic benchmarks, so that we can better compare them to real world applications. The OCZ Kit is slower in lower speeds compared to Patriot, but improves the higher the speed. We could bench memory with 1904MHz, but memory intensive applications such as GordianKnot crashed. As always speed improves with a higher FSB.
Everest benchmarks shows no significant differences. Of course, higher clockspeed can improve the rates and we compared scores only at the same CPU speed.
Everest also benchmarks the latency, higher clocks means more latency, but low frequency with low latency needs higher latency on the chipset, which increases access latency a lot. On our board the chipset latency was locked with "Boost 0" settings, so only the frequencies were altered.
