4. Installing CPU & Housing Fan
Plug in the CPU fan cable to the 3-pin CPU FAN connector. If you have chassis fan,
you can also plug it on FAN2 or FAN3 (without H/W monitoring) connector.
Pull up the CPU socket lever and up to
90-degree angle.
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.
Press down the CPU socket lever 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.

5. Setting CPU Voltage & Frequency
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, and no jumpers or switches are needed.
BIOS Setup > Frequency / Voltage Control > CPU Speed Setup
Core Frequency = CPU FSB Clock * CPU Ratio
CPU Ratio 2x, 2.5x, 3x, 3.5x, 4x, 4.5x, 5x, 5.5x, 6x, 6.5x, 7x, 7.5x, and 8x
CPU FSB (By BIOS table) 66.8, 68.5, 75, 83.3, 100, 103, 112, 117, 124, 129, 133.3, 138, 143, 148, 150MHz.

Tip: If your system hangs or fails to boot because of overclocking, simply use <Home>
key to restore the default setting (433MHz) or you can wait the AOpen "Watch Dog Timer"
reset the system in five seconds and system will auto-detect hardware again.
