Plug in the CPU fan cable to the 3-pin
CPUFAN
connector. If you have chassis fan, you
can also plug it on
SYSFAN1
or
SYSFAN2
connector.
5. Setting CPU Voltage & Frequency
3. Installing CPU & Housing Fan
Note: Some CPU fans do not have
sensor pin, so that cannot support
fan monitoring.

Setting CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be
automatically detected and the range is from 0.8V to 1.55V. 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 Clock * CPU Ratio
CPU Ratio
From 4x to 25x step 1x
CPU Clock (By manual
Adjustment)
200~255 by 1MHz stepping adjustment technology

4. Connecting ATX Power Connector
This motherboard comes with a 20-pin and 4-pin ATX power connector. Make sure you plug
in the right direction.
Warning: NVidia nForce3 chipset supports 200MHz system clock and 66MHz AGP
clock, higher clock setting may cause serious system damage.
Tip: If your system hangs or fails to boot because of overclocking, simply use <Home>
key to restore the default setting or you can wait the AOpen “Watch Dog ABS” reset
the system in five seconds and system will auto-detect hardware again.
Warning: Supposed you have had adjusted CPU ratio on your current CPU, and you
plan to replace a new CPU. Please use <Home> key or Clear CMOS to restore the
default setting when changing a new CPU, because the system will still implement the
previous CPU setting on the new one.
