Performance Comparisons

Performance of the OCZ EL PC4000 VX Gold was compared to all of the memory recently tested on the AMD Athlon 64 platform. While we did not test on an Intel platform, the performance results can also be generally compared to previous benchmark results on the Intel 875 memory test bed.

AMD Memory Performance Comparisons

OCZ EL PC4000 VX Gold was compared to other memory included in recent Athlon 64 Memory Reviews. This included all tested memory since the launch of the A64 memory test bed in Athlon 64 Memory: Rewriting the Rules . Memory performance was compared at 200x12 (2.4Ghz, DDR400), 218x11 (2.4Ghz, DDR438), 240x10 (2.4Ghz, DDR480), 267x9 (2.4Ghz, DDR533), the Highest Memory Speed that could be reached, and the Highest Memory Performance Settings that we could reach. With a constant CPU speed, memory comparisons (except for top-speed and performance) show the true impact of faster speed and slower memory timings on memory performance.

    Hi I would like to know if u think that thoose dimms could be enough cooled by a 120 mm fan in extraction and a 120 mm fan from a power suply

    Because i would like to put thoose dimm in antec Sonata and as it's a small case i don't know if i will have enough space to put a fan

    Figured it out, seems like the cpu speed plays a role here. 2.25 ghz maxes out at 6600-6700. 2.34 gets 6900-7000. I wonder if going even higher will set a new bandwidth record.

    Hmm, I can't seem to duplicate the results here and I don't know what I'm doing wrong. I have 2 sticks of pc3200 ocz vx and a dfi ultra (non-sli). I have the ram running at ddr500 at 2-2-6-2 T1 @3.3v and sandra reports a bandwidth of 6000-6100. The weird part is that sandra reports a timing of 2T but if I drop the timing from 1T to 2T in the bios, the results drop to 5700 so I'm pretty sure 1T is enabled. Any ideas?

    I would like you to help me with a MotherBoard/RAM question.



    I’m about to buy a DFI Lanparty NFORCE 4 Ultra MB with 2 GB of RAM.

    This machine will be for audio sampling and recording, and some gaming too J



    I’m worried if it can run 2 GB of RAM at DDR400, I don’t know if it will drop the memory speed with this config.



    I would like to buy 4x512 KINGSTON PC3200 ULTRA LL 2-2-2-5, but as they are double sided, maybe they will run at DDR333

    The 2nd option would be 2x1024 of OCZ memory PC 3200 3-3-3-7 OCZ4001024PF, is its performance good with this latency?



    I have searched lots of forums and didn’t find a final word about this issue.



    What would be the best performance choice? Do you think it can work?



    Thank you very much,

    Alexandre Zumbi.

    iirc, the dfi was tuned for tccd and bh-5/vx.
    other stuff that overclocks somewhat does terribly on the dfi, that includes ballistix's micron 5b-g chips.
  • L3p3rM355i4h - Wednesday, March 9, 2005 - link

    hmm...good performance, but also a lot of questions. How well does ballistix do on the mobo?

    For everyone hung up on the on-board memory controller...

    The motherboard will make a difference for the on-board memory controller, not because of the chipset, but due to the characteristics of the routing. The type of material used, the thickness and width of the copper traces, and how well the traces are matched in length, will all make a huge difference in signal integrity. Even differences in what layers of the board you route to make a difference, and what power plains they're coupled against are. The list goes on...

    DFI put a lot more effort into their routing, and it makes a significant difference.

    #56 - Wow. Thanks for pointing this out. This review is bogus. I hope that you cc'd Mr. Shimpi on that e-mail.
