With this motherboard, AOpen provides a very special, useful feature for overclockers. When you power-on the system, the
BIOS will check last system
the CPU FSB frequency by user's setting that stored in the BIOS. If system failed in BIOS POST, the "Watch Dog Timer" will
reset the system to reboot in five seconds. Then, BIOS will detect the CPU's default frequency and POST again. With this
special feature, you can easily overclock your system to get higher system performance, and without removing the cover of
system housing to set the jumper to clear CMOS data when your system hanged.
