Setting CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected and the range is from 1.3V to 3.5V.. 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, no jumpers or switches are needed.
BIOS Setup > Frequency / Voltage Control > CPU Speed Setup
Core Frequency = CPU FSB Clock * CPU Ratio

5. Setting CPU Voltage & Frequency
4. Installing CPU Fan
3. Installing CPU
1.
Pull up the CPU socket level and up to
90-degree angle.
2.
Locate Pin 1 in the socket and look for a
(golden) cut edge on the CPU upper interface.
Match Pin 1 and cut edge. Then insert the
CPU into the socket.
3.
Press down the CPU socket level and finish
CPU installation.
Note:
If you do not match the CPU
socket Pin 1 and CPU cut edge well,
it may damage the CPU.

connector.

SENSE
Note:
Some CPU fans do not have
sense pin, so that cannot support fan
monitoring.
Warning:
VIA Apollo Pro 133 chipset supports
maximum 133MHz FSB and 66MHz AGP clock, higher
clock setting may cause serious system damage.
Home
Tip:
If your system hangs or fails to boot because of overclocking,
simply use <Home> key to restore the default setting.
