3. Connecting ATX Power Connector
The ATX power supply uses a 20-pin connector shown below. Make sure you plug in the
right direction.
4. Connecting Front Panel Cable
Attach the power LED, speaker, and reset switch connectors to the corresponding pins. If
you enable "Suspend Mode" item in BIOS Setup, the ACPI & Power LED will keep flashing
while the system is in suspend mode.
Locate the power switch cable from your ATX housing. It is 2-pin female connector from the
housing front panel. Plug this connector to the soft-power switch connector marked SPWR.

5. Setting CPU Voltage & Frequency
Full-range Adjustable CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected and the range is from 1.1V 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.
BIOS Setup > Frequency / Voltage Control > CPU Speed Setup
Core Frequency = CPU FSB Clock * CPU Ratio

Note:
With CPU speed changing rapidly, there might be fastest CPU on the
market by the time you received this installation guide. This table is kindly for
your references only.
Warning: nForce2-ST/GT chipsets support 166MHz FSB (with performance reaches
maximum 333MHz EV6 system bus) 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
Timer" reset the system in five seconds and system will auto-detect hardware again.
Note: You have to
