    A7N8X BIOS Rev 1004
    AMD XP 2600+
    2x HyperX 512/3200 CAS2
    XP Pro SP1+
    Nvidia Nforce2 v2.41



    I bought 2 Kingston HyperX 512/3200 today to replace a single Crucial 512/2700 CAS 2.5.. I get home and pop them in with the new BIOS mem FSB set to 200MHz.. I run the SiSoft Sandra bandwidth benchmark and get a terrible score..

    here's some bench results with different settings:

    Module Name -- FSB Integer float

    HyperX 512/3200 166 2389 2254

    HyperX 512/3200 200 2232 2148
    Single channel
    2-2-2-6

    Crucial 512/2700 166 2389 2225
    Single channel

    2x HyperX 512/3200 166 2359 2289
    Dual channel

    2x HyperX 512/3200 200 2260 2184
    Dual channel

    as you can see, the HyperX is not running at PC3200 speeds.. either it is PC2700 mistakenly packaged as PC3200 or there is a problem with PC3200 on my board..

    I'll be trying out the memory in another machine asap to see if the problem is duplicated..

    has anyone else heard of this problem before or is this just a freaky thing?

    PS sorry, the numbers get squished too close to each other

    ok, never mind, I figured out the problem.. being a noob at this I didn't know to set my cpu fsb too 200..

    I finally figured that part out and have been playing with multipliers.. right now I'm running the 2600+ @2300MHz (11.5x200 @ 1.7v).. I'll have to see how the rig runs for a while o/c..

    anyhow, the benchmarks are up where they should be.. I tested a single 512/3200 and got the following results:


    Module Name -- FSB Integer float

    HyperX 512/3200 200 2859 2651
    Single
    CPU = 2100MHz
    2-2-2-6

    HyperX 512/3200 200 2874 2658
    Single
    CPU = 2200MHz
    2-2-2-6

    HyperX 512/3200 200 3021 2793
    Single
    CPU = 2300MHz
    2-2-2-6


    Wow, is all I can say.. what a major boost in performance..
