I built a computer for a customer and I decided to try a Gigabyte motherboard instead of my usual choice of Abit. I ordered a Athlon XP 2800 to go with it and it's set at 1250mhz right now. I went into the BIOS and looked around for the option to change the processor speed and its not there like it is on most motheboards BIOS's. I did upgrade the BIOS with the "windows utility" that came with the motherboard CD, but still no luck. Any help is appreciated.
