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.

    I was curious why new video drivers would make a difference in speed in the tests where the video subsystem is not involved. Anyone?

    In soviet Russia memory overvolts you!

    you're my hero Wesley. thanks for going through and redoing the benches with the dfi. looks like you were right about the VX being faster at the same timings and speed.. though it still doesn't make sense to me. i'll have to do a bit of research into it.

    two things i'd like to say about the review though:

    first, a recommendation for an additional test. use the memory latency benchmark in everest ( ). i have found that in my testing, the lower the latency, the better (duh) but if the latency is different for each ram at the same speeds and timings, it would definitly imply that not all ram is equal at equal settings.. which is what we're seeing here.

    second: why so much voltage for ballistix at low speeds? i have two sticks of the stuff myself, and have found that it helps tremendously if the drive strength is lowered to level 1 or level 2 on my dfi lanparty nf3-ut. i know the nf4 version is different, but it's something to keep in mind with tweaking.
