speaking, if you are not an overclocker, we recommend you to set at the default setting.
Plug in the CPU fan cable to the 3-pin CPUFAN connector. If you have housing fan,
you can also plug it on FAN2 connector.

CPU Core Voltage Auto-Detection
This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected. 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.
BIOS Setup > Frequency/Voltage Control > CPU Host Clock (CPU/PCI)
Core Frequency = CPU FSB Clock * CPU Ratio
CPU Ratio 3x, 3.5x, 4x, 4.5x, …16x
CPU FSB 66.8, 75, 83.3, 100, 103, 105, 110, 112, 115, 120, 124, 133, and 150MHz

Tip: If your system hangs or fails to boot because of overclocking,
simply use <Home> key to restore the default setting.
Warning: VIA PLE133T chipset supports
maximum 133MHz FSB, higher clock setting may
cause serious system damage.
Note: Some CPU fans do not have
sensor pin, so that they cannot
support fan monitoring.
