Re: AMD Processor question.
no, cool and quiet is not available on the xp's. partly because they run so much hotter than the 64 bit processors.
Look around in your bios for Bus Frequency: this should be set to 133mhz stock for your computer. Now somewhere close to that you should find something called the multiplier: this should be set to 15. 133 x 15 = 1995 or approx 2.0ghz, which is what your processors speed should be given the link you posted. Check these setting and make sure there right, chances are at least one of the 2 is wrong.
If they are not, flashing your bios is the next option, your bios may be out of date causing it to not properly recognize your processor.
