This motherboard comes with a 20-pin and 4-pin ATX power connector as shown below.
Make sure you plug in the right direction. We strongly recommend you to insert the 4-pin
connector before connecting the 20-pin connector.

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 0.8375V to 1.6V. It is not necessary to set CPU Core
Voltage.
Setting CPU Frequency
This motherboard includes CPU jumper-less design, you can set CPU frequency through
the BIOS setup, and no jumpers or switches are needed. The default setting is "table
select mode". You can adjust the FSB from "CPU Bus Frequency" for overclocking.
Warning:
SiS648FX/SiS963 Chipset
supports maximum 800MHz
system bus and 66MHz
AGP clock; higher clock
setting may cause serious
system damage.
Note:
SiS648FX/SiS963
Chipset only support
Northwood processor, and
don’t support Willamette
processor. Northwood
processor would detect
the clock ratio
automatically, you may not
be able to adjust the clock
ratio in BIOS manually.
BIOS will show the
adjustable settings for
customers to choose.

3. Connecting ATX Power Connector
4. Front Panel Connector
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
