    Go into your bios and make sure that the fsb(front side bus) is set to 166mhz

    Your cpu should now be at the correct speed.

    Yes sorry the AMD xp 2600+ comes in several different flavours either running at 166mhz fsb or 133mhz fsb.

    Go back into your bios and set the fsb to 133mhz that should do it.

    The only thing i can think of is that the multiplier is set to 12.5 instead of 16.

    But I don`t know what would cause this as usually the mobo should detect the correct multiplier for your cpu.

    I will try and find out and get back to you when I know more.

    Regards Howard :(

    some cpus will not properly run at thier specified speeds, it happens all too frequently with AMD processors, a problem that has plagued AMD since thier k-5 and knockoff 486's. you may have to settle for a slower speed or change your hardware/bios version.

    Just a thought. have you tried clearing the cmos?

    This will set your bios to the default settings.

    Then after clearing cmos you can go into bios and set the fsb to 133mhz.

    Maybe the mobo will then detect the correct multiplier for your cpu.

    I don`t know if this will work but I think that it`s worth a shot.

    Is it OEM or retail CPU? Maybe it's defective.

    when i set my fsb to 133mhz, my computer was restarting every 10 minutes... i set it back to 100mhz and it hasn't restarted yet.. clearing the cmos... you mean taking the cmos battery out and putting it back in?

    You can clear the Cmos by taking the battery out for about 20 seconds or so and then putting it back in.

    Also you can clear the Cmos by using the jumper on your mobo. Take a look at your mobo manual.

    You can reflash your Bios back to the old version.

    Usually when you flash Bios it asks you if you want to backup the old Bios, did you do this. If so just select that version to flash.

    If not you will have to find and download the old version of your Bios and reflash.

    Your mobo book or mobo disk may tell you what version of Bios it was using.

    Other than that it may be tricky but you could try contacting MSI and asking them.

    so i'm guessing there's no way to reset the bios to its original revision without flashing right
