AOpen provides a special and useful feature on this motherboard for overclockers. When you power-on the system, BIOS will
check last system
POST
status. If it succeeds, the BIOS will enable "Watch Dog Timer" function immediately, and set the CPU
frequency according to user's settings stored in BIOS. If system fails in BIOS POST, then "Watch Dog Timer" will reset the system
to reboot in five seconds. BIOS will detect the CPU's default frequency and POST again. With this special feature, you can easily
overclock your system to get a higher system performance without removing the system housing and save the hassle from setting
the jumper to clear CMOS data when system hangs.
