Comments:

Corsair LL (TwinX): Everything ran smoothly.

Crucial: Our Crucial modules completely failed to work at all with the MSI 865PE Neo2-FIS2R. We were able to POST but unable to enter the BIOS at any time.

Kingston HyperX: Everything ran smoothly. We were forced to lower the Performance Mode option to Turbo instead of Ultra-Turbo to get SPD and manually programmed memory timings to function. Also, while manually programming these modules timings, we were unable to reach CAS 2.0 without the Neo2-FIS2R dropping the memory frequency to 320MHz DDR. CAS 2.5 was the lowest we were allowed to go to be able to operate at 400MHz DDR.

OCZ EL: Everything ran smoothly. We were forced to lower the Performance Mode option to Turbo instead of Ultra-Turbo to get SPD and manually programmed memory timings to function.

TwinMOS: Everything ran smoothly. We were forced to lower the Performance Mode option to Turbo instead of Ultra-Turbo to get SPD and manually programmed memory timings to function.

    Great article. I set my watch by you guys. Most of my decisions about computer hardware is based on your very helpful articles. keep up the great work.

    I noticed in your artical you use Hyper-x 3500. I purchased the Gigabyte 8KNXP and Hyper-x 3200, to my disappointment they are not compatible! Kingston has ignored all e-mails about this problem. I would not recommend any of their products if using this motherboard.

    At the moment looking for good memory for my Epox 4PCA3+ mainboard I purchased recently. Seems to be difficult to get the TwinX modules from Corsair (512 MB CL2) here in Holland, if you know a "cheap" supplier please post here...

    This article, this website very useful! In my favorites... YV

    This is a very useful article. Not only do we see just numbers indicating which manufacturer makes the most fastest memory but also in "final words" the author discusses some alternatives.

    Excellent!

    Why was Mushkin not included in this test? Also when will we see a similar test on the NForce2 boards?

    How about twinmos? You only commented on the other three. In my country, only kingston and twinmos are available and unfortunately, hyperx is a lot more expensive than twinmos!

    Well I'm just about to upgrade my PC and saw the TwinMOS package @ addonsonline.co.uk for £60. Sounds good for 512MB. I downloaded the CPU-Z program and checked the timings of my Crucial 256MB PC2100 DDR and to my suprise the CAS Latency is 2, RAStoCAS is 2, RAS Precharge is 2, and Cycle Time is 4???? is this not a bit fast???? OR is slower clocked memory able to run @ faster timings??

    Further comment to the above...
    DDR-II is on the near horizon BUT will it be the answer for super-fast compatible memory?

    New memory design, structure and packaging will probably require mew motherboards.(I envisage "teething problems" etc.)

    Incompatibility will still probably reign!

    One wonders if these "compatabilty charts" still hold for larger sizes of memory like 2 off 512MB?

    What happens with greater than 1GB?

    Are these REALLY new technologies or older DDR ones being "Officially Overclocked"?
    viz ONE BIOS DOES NOT SUPPORT <2.5 CL

    Memory with CL=2 are from CHOICE chips.
    Memory with CL=2.5 seems to be the norm.
    Thus memory with CL=3 are easily overclocked to CL=2.5.

    Interesting article.
    What does the graph show.
    It has numbers at the end of the bars (e.g. 339.6) - what is it a measurement of.
    Is a larger number better or worse?
