Computer Slow after RAM upgrade.

  1. hi

    Hope u can help me on this one..

    I have an Amd athlon 64 3400+ with
    3Gb DDR 333 166Mhz. Corsair (TWINX2048-3200C2PT) 400MHz/PC3200 PC Memory non-ECC unbuffered 2-3-3-6 Silver Heat Spreader.
    Motherboard Asus K8N-E Deluxe further details of MB are below
    4 HDD; 2 Sata and 2 IDE
    And I'm running windows XP SP2

    However since ive upgraded my memory from 1GB to 3GB , my computer has become very slow.

    I don't know if the RAM upgrade has anything to do with it, but it seems like it. Has it started after the upgrade.

    It takes ages to shut down. It stays with the blue screen for 20min at least, before eventually shutting down.
    Also if i open more than one window it hangs up.
    It takes ages to do anything, from opening web browser to explorer windows.
    Onlywhen i re-start it works properly for a while before doing it again.

    I have read in a few forums that it could be related with the paging file, however i changed the paging file to 4500 (correct me if im wrong, the paging file should be 1.5 times more than the RAM) and it still does not work properly.

    Im clueless on how to solve this issue.

    Any help is more than gratefull

    Thanks in advance.

    You will probably have to change the memory timings or voltages manually in the bios. Just because a motherboard "says" 3GB max, it doesn't mean that it will actually work right. Does the computer speed back up with only 2GB installed?

    Perhaps the paging file is fragmented. Delete the paging file in control panel (Start->Control Panel->System and eventually get to select "No Paging File"). Then, defrag in safe mode, boot back to normal mode and reinitiate the paging file. You might also simply try to see how fast it runs without the paging file at all in normal mode. If fast, this would tell you it's fragmented.

    best is to let windows set paging file size
    or set it to 3 times the commit charge of your system

    re-set paging to allow windows to set it
    then do :
    open 3 programs you use
    do ,control alt delete look at the memory amount ( commit)
    make paging 3 times this size
    best at this point to remove it and start with fresh de-fragged paging
    without the PAE switch xp 32bit will not use over 3gb of memory so setting paging above that does not do anything
