Performance Test Configuration


We tested the Geil PC3200 Ultra X in our standard Intel Pentium 4 Memory testbed. The hardware for evaluating the Ultra X memory is the same used in our earlier reviews of DDR400 and faster Memory.

All test conditions were as close as possible to those used in our earlier memory reviews. We have also eliminated from our charts any memory that has been discontinued, including Winbond BH5 and BH6 versions from several vendors and earlier versions of several current memory products.

We have found the fastest performance on Intel 865/875 to be achieved at Cycle Time or tRAS of 5, or the fastest tRAS setting that is stable with the tested memory. Intel platform benchmarks were therefore run with the fastest stable tRAS timings we could achieve with the Geil Ultra X.

Test Settings

We ran our standard suite of memory performance benchmarks. The following settings were tested with the Geil DDR400 2-2-2 memories:
  1. 800FSB/DDR400 - the highest stock speed supported on 875/865 and K8T800/nF3/SiS755 motherboards
  2. 866FSB/DDR433 - a speed rating we have used in testing other lo-latency DDR400 memory
  3. 933FSB/DDR466 - another speed rating we have used in testing low-latency memory
  4. 1000FSB/DDR500 - a standard memory speed used in testing other high-speed memory
  5. 1066FSB/DDR533 - only two DDR400 2-2-2 memories reached this memory speed and results from those tests are included for comparison
  6. Highest Stable Overclock - the highest settings we could achieve with this memory and other memory we have tested
These are the same general settings used in benchmarking other DDR memory in past year. DDR400, DDR500 and Highest Memory Speed have been used for all benchmarking. DDR433 and 466 were also used for testing other DDR400 2-2-2 modules so we also ran benchmarks at these timings for comparisons. We also included test results at DDR533 for the two DDR400 2-2-2 memories that reached that speed and beyond.

    excellent read thanks Anandtech for the useful info
  • Avalon - Friday, August 20, 2004 - link

    Forgot to mention it was tested on an A64 rig. If you've got an AXP rig, lower latency might mean more. I should go test it out...
    Anyway, great article Wes! It's good to see Geil come out near the top. They make some great memory and are very under-recognized sometimes.

    I forget where I saw it, but I did see latency compared in a Doom 3 article. Low CAS 2 latency benefitted over CAS 2.5 by giving you roughly 2-3% more framerates. Which added up to about 1 frame. Since I can't quite remember where I found it, take this with a large boulder of salt :P

    I am wondering the same thing as #5. It would be very interesting to see a comparison between the Value RAMs and these.

    Anyways, great article.
  • Visual - Friday, August 20, 2004 - link

    This isn't really in the goals of this article, but I'm wondering, is the extra-low latency worth it at DDR400?

    Could you include a slow(Value RAM) memory from Kingston, Corsair or other, running at CAS 2.5 and 3 for comparison?

    I really wanna know if the extra $100 or so for a low-latency ram would give me noticeable difference.

    Mr Fink!!!! Another GREAT READ!!!! I so LOVE these memory articles of yours. SO informative and give much food for thought.

    Thanks and keep up the gd work! ;)

    #1 - Corrected. We are missing our Web Editor who is taking a well-deserved vacation.

    #2 - You make an interesting point. I was leaning toward Samsung TCCD chips, particularly based on the poorer overclocks on Athlon 64, but I agree there are some timings at certain speeds that don't really fit. Hynix also exhibits poorer A64 overclocks compared to Intel, so it is a possibility.
  • Zebo - Friday, August 20, 2004 - link

    Nice work Wes. To bad we don't know what chips they have...I'm leaning twards hand picked Hynix that can do 2-2-2 @ 200 by the way it mirrors it's brothers at higher bandwidth...in addtion to it's bandwidth.

    Just a couple of things you might want to fix, on the bottom of page 2 it has the title "OCZ PC3200 Platinum Revision 2 Specifications" which should be "Geil PC3200 Ultra X Memory Specifications". Also on page 4 at 557DDR speed the Quake3 fps is missing a decimal and is listed as 43486 instead of 434.86 fps. Other than that great review, awesome looking ram man!
