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 FSB frequency

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.
