On the Athlon64 system, according to PCMark, all the systems are about the same at stock speeds. Tighter timings seems to give a 100-200 point boost to score. On the Intel side the DIMM's that run with tighter timings score slightly higher. When overclocked, nothing can match the Buffalo Firestix FSX5000V RAM.

PCMark04 is the latest version of the popular PCMark series. PCMark04 is an application-based benchmark and a premium tool for measuring overall PC performance. It uses portions of real applications instead of including very large applications or using specifically created code. This allows PCMark04 to be a smaller installation as well as to report very accurate results.

In PCMark04, the situation is much closer... but again, the Buffalo Firestix FSX5000V RAM is slightly slower than the memory modules which run with tight timings. When overclocked, the Firestix FSX5000V RAM has a nice lead on the Intel system.
