Your motherboard has dipswitches on it for setting up the FSB. This will let you adjust the speed of the CPU. However, you might want to make sure your Memory is running at the same speed instead of pushing the frequency at 3:4 FSB:MEM.
SW1 is where you adjust the FSB. The manual has the combinations listed. If you lost your manual, you can DL it from <A HREF="http://www.giga-byte.com" target="_new">http://www.giga-byte.com</A>.
