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 ABS” 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.
