Tip:
If your system hangs or fails to boot because
of overclocking, simply use <Home> key to restore
the default setting.
Setting CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected and the range is from 1.10V to 1.85V. It is not necessary to set CPU Core
Voltage.
Setting CPU Frequency
This motherboard is CPU jumper-less design, you can set CPU frequency through the
BIOS setup, and no jumpers or switches are needed.
Core Frequency = CPU FSB Clock * CPU Ratio
