With this motherboard, AOpen provides a very special, useful feature for overclockers. When you power-on the system, the BIOS
will check last system
will check last system
status. If it succeeded, the BIOS will enable “Watch Dog Timer” function immediately, and set the CPU
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 without removing the cover of system housing, and be able
to set the jumper to clear CMOS data when your system hanged.
