    SN41G2 overclock help needed

    hi guys as you can see from the screen shot my amd 2500 is overclocked and windows reads it as a 3200! but i can't get the damn ram right! it won't let have the ram which is 3200 stuff run @ 200mhz which is 400, so i have to run it @ sync which is around 383.

    if i change the FSB back to 166 i can get the ram to 200mhz which is the default speed,

    On Socket A, you want the RAM to be in sync with the FSB of the CPU - otherwise, it slows the computer down. Since the RAM is nearly running at 400DDR anyway, I would leave it how it is.

    Have you tried the NVIDIA System Utility?

    Lets you change the fsb and RAM timings after you've booted up, so you can boot up with stock settings and overclock once it's up and running. That way you can check whether it will actually run like that and if it reboots then you're back at stock settings.

    Normally I can't get my 2500+ as far as you've got yours, but just checking it with relaxed memory timings to see if it will work.
    If you can't keep up, stick with reality...

    Are you using the on board graphics?

    Because my shuttle, at least, won't go to DDR 400 when you are using on board graphics see here

    There is of course the chance that seeing as the 2500XP wasn't designed to run with an FSB of 200mhz your particular chip hasn't got the head room.

    I know myself I have 2 of the damn things and I can't get either to run at 200mhz and I've had them in 3 different motherboards. One is unlocked and the other isn't and even in the NF7-S V2.0 which is pretty much the daddy of socket a boards it just will not run stable at 200mhz.

    Sorry to cast a pesitmistic view on things
