AOpen provides a special and useful feature on this motherboard for overclockers. When you power-on the system, the BIOS will check
last system
POST
status. If it succeeded, the BIOS will enable "Watch Dog Timer" function immediately, and set the CPU
according to user's settings 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 a higher system performance without removing the system housing and save the hassle from setting the jumper to clear
CMOS data when system hangs.
