I would guess that you're using an FCPGA CPU and slocket?? If so, make sure that the FSB on the slocket is set to either deault or 100 FSB. Also, most of the better/newer slockets also have a jumper where you indicate whether you're using an original celeron or a coppermine(PIII's and Celeron II). If you're using a slocket, which one?? If this is done, it should be recognized as a 700 MHZ CPU. Then go into the BIOS and try to overclock. Might need more information to come up with additional possibilities.
