Watch Dog Timer
This mainboard comes with a special feature called “Watch Dog Timer” which is used
to detect when the system is unable to perform ok the manual over-clocking
configurations. After you power on the system, BIOS will check the last system post
status. If it was successful, BIOS will enable the “Watch Dog Timer” feature and set the
CPU frequency values to the user configured values stored in the BIOS. If unsuccessful
the “Watch Dog Timer” will reboot the system.
Typically, you would not need to remove the cover of your system and re-jumper the
clear CMOS switches on the mainboard when your system encounters over-clocking
problems. With the “Watch Dog Timer”, overclocking settings will be automatically
cleared and reset.
Before Overclocking
Please make sure your system components are capable of overclocking.
If you are not familiar with the overclocking function, we strongly
recommend that you to set the clock to the default settings.
