OCZ 4GB DDR2 PC2-6400 VP Platinum Dual Channel
HH Test Bed and SANDRA XI Testing
For comparison purposes, we used an OCZ PC2-8800 Gold series kit that was rated at 5-6-6-15. However, since our system peaks at 800MHz, we were able to match the timings with the 4GB Platinum series 5-4-4-15, making for the best comparison. For good measure, we threw in 1GB of PQI PC2-4200 DDR2 with timings of 3-3-3-8 more so as a reference point than a comparison. Some may question our use of 64-Bit Windows XP Pro rather than a version of Vista. In short, we opted for the most stable platform for testing, which is still Windows XP.

We began our testing with SiSoftware's SANDRA, the System ANalyzer, Diagnostic and Reporting Assistant. SANDRA consists of a set of information and diagnostic utilities that can provide a host of useful information about your hardware and operating system. We ran SANDRA's Memory Bandwidth and Latency tests to assess each memory kit's performance characteristics.
In overall bandwidth, the two OCZ DDR2 Gold and Platinum Edition kits performed similarly, with the Platinum 4GB kit holding a lead of roughly 200MB/s across both Floating Point and Integer tests. In latency testing, the two OCZ kits were tied at 95ns while the older PQI 1GB Turbo series lagged significantly even though its timings were much more aggressive than each OCZ kit.
