    Memory: 4 x 512 or 2 x 1gig stick??

    <Newbie question warning on>

    Getting ready to build a dedicated GS3 box.

    Is there a performance difference between a system using 2 x 1gig sticks over using 4 x 512?

    The guy a Fry's was telling me something about better performance using a Dual Channel kit... Corsair "Twin X" 4 X 512...

    What d'ya think?

    Thanks,
    Studio

    dual kits give nothen the a guarantie that it will work in dual mode.
    nothin else. for p4 cas latency dosent matter that much.
    for athlon 64 it does a bit more.
    i compared memory with optimal latency timings to ones with normal 3.8.3.3 timings and the difference was not much. 2 voices more or so

    It shouldn't make any differences between either configuration. It still dual channel mode with the same throughput. Although there are some slight differences according to the document below. Fry's may just be trying to sell you the more expensive 1 GB sticks.

    Here's an interesting Intel 875 memory white paper: ftp://download.intel.com/design/chip...s/25273001.pdf

    4x512 double sided DIMMS appear to be the fastest combination with a rank of 1. Whereas the 2x1 GB doublesided are ranked 2. So the 4x512 may actually have better performance.
