In our recent review of OCZ VX memory, we compared OCZ VX tested on the DFI nF4 SLI-DR to our past results of memory tests on the MSI nForce3 Ultra testbed. We were comfortable in our results based on past reviews that showed performance of the nForce3 and nForce4 to be essentially the same as well as AGP and PCI Express performance being essentially the same in the benchmarks that we use for memory testing. However, we did find after the review that there are performance improvements in the move from nVidia 61.77 drivers to the 71.80/71.84 drivers used in the DFI benchmarks.
Subsequent testing also revealed the memory overclocking capabilities of the DFI to be slightly better than the MSI K8N Neo2, so the fairest way of comparing the new OCZ VX PC4000 was to rerun memory tests of some of the top categories of DDR memory for the Athlon 64 platform. We benchmarked OCZ PC4000 VX, Crucial Ballistix PC3200, Corsair TwinX1024-4400C25, and OCZ PC3200 Platinum Rev.2.
All 4 memories were retested on the DFI LANParty nF4 SLI-DR using the same components and driver versions. This should clearly show the comparative performance of these four top memories on the nForce4 platform.
