In the past year, we have seen lots of memory rated at DDR500, so you may wonder why we are reviewing a new DDR500 memory today when there are now a few rare modules rated as high as DDR600. The answer is pretty simple, since OCZ PC4000 VX Gold is the only memory that we have ever seen rated at DDR500 2-2-2. While it is rated at DDR500 at these extraordinary 2-2-2 timings, it also carries a very high rated voltage of 3.3V - far beyond what most motherboards can supply.

A quick check of orbs at FutureMark will show that this new VX is the fast darling of the extreme overclocking market. For those who wondered why DFI included voltages to 4.0V in their new nForce4 Ultra and SLI motherboards, the answer is OCZ VX memory. With VX needing voltages as high as 3.7V to really reach top performance at certain speeds, the DFI LANParty nF4 SLI-DR and DFI LANParty UT nF4 Ultra-D are the first production motherboards to support the kind of extreme voltages needed by VX without modification.

With this promise of extraordinary DDR500 2-2-2 performance, we were very interested to see if this performance promise was real. Have we finally reached DDR500 with the fastest timings available? The answers in our benchmarks are very interesting.

    sorry, of odes = or does!

    intirely = entirely

    Any ideas when this RAM is available\where from?
  • theOracle - Saturday, March 5, 2005 - link

    Some of the figures show over 10% performance increase (the actual game benchmarks, not just memory benches) - is this performance intirely attributable to the RAM of odes the motherboard\gfx come into play at all?

    Previously high-end RAM with tight timings has shown an improvement of a couple of fps - say max 2% overall, yet this is showing figures of 10% improvement - which like I say is like going from a 3500+ to a 4000+ - and I'm pretty certain that the DFI board, this ram and a 3500+ would be cheaper than a 4000+, generic ram and a cheaper mobo.

    Wesley - can I suggest a follow up, with this RAM on other boards and a direct comparison of RAM on the same setup, because I think the benchmarks you have shown certainly warrant this being done. You cant blame me for being sceptical when the figures are so unbelievably awesome!

    #34 - The other RAM did NOT perform identically, it is just that there was much smaller variation in the results than we saw with the leap in VX performance.

    Perhaps it will be easier to swallow if I point out that the OCZ 3200 Platinum R2, PQI 3200 Turbo, G. Skill TCCD, Geil PC3200 Ultra X, and Corsair TwinX1024-4400C25 are all based on the same Samsung TCCD memory chips. The Crucial Ballistix is based on Micron chips, and the OCZ 3700 Gold R3 is based on Hynix DT-D5 chips. Until VX, all recent memory has had to compete with Samsung TCCD, which quickly became the performance standard for current memory. If we had results from older BH5 chips you would likely have seen BH5 perform between Samsung TCCD and OCZ VX.

    I find some of these results rather difficult to believe, not so much the results of the OCZ DRAM but I'm confused as to how the other DRAM in this test managed to perform identically in every test on the MSI K8N Neo2 that was used in your last DRAM review and the DFI motherboard utilized in this review.

    It would seem rather unlikely that every piece of DRAM would perform exactly the same in every test on two different motherboards.

    I have the 3200vx and they perform very similarly(i think they are the same ram but just different auto settings lol) I will post screenie and stuff on forums when i can run some concrete bench marks.

    These are winbond chips that can also be found in twinmos. Dont know if this is mentiond in the article as I did not read all :)

    Check out this link for info on speeds and which ones to get:

    Wesley: I'm confused by your answers to #15/#17. Did you actually test all 8 types of RAM on the DFI LANParty nF4 SLI-DR with nVidia 71.80 drivers, or did you take the benchmark results for the other 7 sticks of RAM from the previous review of the Corsair 4400C25, which used an MSI nF3 motherboard and the 61.77 drivers? (All the numbers seem to be the same, which I find hard to believe with a new motherboard, chipset, and video drivers. I would expect at least a couple of variations of 0.1 fps or something.)

    Awesome... I always wondered about Tras and the Athlon-64... this answers my question! :)
  • Slaimus - Friday, March 4, 2005 - link

    These are Winbond chips. The BH/CH-5/6 chips were their own branded chips, while these are unlabelled OEM chips that are sold for relabelling. The supply of the labelled Winbond chips are gone, but there are still plenty of these unlabelled chips.
    This really gives you an idea of the cartel nature of the memory industry. Small memory makers like Winbond, despite having a superior product, cannot really stay alive in this market of giants.

    thanks for the info wes. if it's not too much trouble, how about a test with the VX on the neo2 with a ddr booster? you say that it's just a better performing ram chip, i'd like to believe you, but it really is difficult to swallow.

    and.. the fact that this ram is so much faster really is piquing my interest, and shows that even if you don't have extreme voltage, this ram may be nice to have for the higher performance at the same speed/timings.

    if it doesn't take too much time, i, and i'm sure a few other people, would be very apprecitative of some benches of vx on the neo2. thanks wes.
