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
1. Plug CPU power 4pins cable to CPU power connector
2. Plug ATX power cable to power connector on board
Above two cables and connector had directional
mechanism. Please plug it according it. If not plug or not
plug properly, the MB will not work.

After you finish the setting of
jumpers and connect correct
cables. Power on and enter
the BIOS Setup, press <Del>
during POST (Power On Self
Test). Choose "Load
Optimized Defaults" for
recommended optimal
performance.
You can use the auto-run menu of Bonus CD disc.
Choose the utility and driver from the icons at left
side, and then click on the “GO” button to complete
installation automatically.

1. Please plug ATX 4Pin Power to the onboard 4 Pins peripherals
connector. It is recommend and must plug while you want to use one
or two PCI Express VGA. This power can provide extra power from
power supply to make sure all peripherals run well. It is POWER IN
connector.
2. Plug PCI Express VGA card properly
3. This MB allow you plug two PCI Express x 16 VGA cards
1. Install remote control’s battery. Please
reference right side picture 1,2,3
2. Install remote control IR senor. Please plug
the sensor’s cable on the Power Master
connector properly. Notice sensor must had
no barriers to block IR signal receive. Please

CPU & System & Power Fans Connectors
Note: Some CPU fans
do not have sensor pin so
they cannot support fan
monitoring.
Plug in the CPU fan cable to the 4-pin CPUFAN connector. If you
have a chassis fan, you can also plug it in PWRFAN or SYSFAN1
connector.

This motherboard provides eight USB 2.0 ports for USB devices
such as mouse, keyboard, modem, printer, etc. There are four
ports on the back panel. You can use proper cables to connect
between Front USB connector and USB modules or chassis front
With IEEE1394 Chip on board (AGERE 1394), having its data transfer rate up
to 400Mb/s, this interface can connect to devices that require high data
transferring performance such as digital camera, scanner or others IEEE 1394
devices. Please use appropriate cables to connect IEEE1394 devices.

JP14 Clear CMOS
You can clear CMOS to restore system default setting. Follow the procedure below.
Turn off the system and unplug the AC power.
Remove ATX power cable from connector PWR3.
Locate JP14 and short pins 2-3 for a few seconds.
Return JP14 to its normal setting by shorting pin 1 & pin 2.
Connect ATX power cable back to connector PWR3.

Tip: When should I Clear CMOS?
1. Boot fails because of over-clocking…
2. Forget password…
3. Troubleshooting…
If the housing has been designed with an audio port on the front panel, you’ll be able to
connect onboard audio to front panel through this connector. By the way, please remove 5-6
and 9-10 jumper caps from the Front Audio Connector before connecting the cable. Please do
not remove these 5-6 and 9-10 yellow jumper caps if there’s no audio port on the front panel.
JP28 Keyboard/Mouse Wakeup Jumper
This motherboard provides keyboard / mouse wake-up function. You can use JP28 to enable or
disable this function, which could resume your system from suspend mode with keyboard or
mouse. The factory default setting is “Disable” (1-2), and you may enable this function by setting
the jumper to 2-3.

Setting CPU Core Voltage
This motherboard supports Voltage ID (VID) function to detect CPU voltage automatically
during power-on.
Setting CPU Frequency
This motherboard is CPU jumper-less design, set CPU frequency through 1MHz stepping CPU
Overclocking in the BIOS. CPU Core Frequency = CPU external frequency x CPU Ratio.
However, all CPU now selling in the market belong to "Fixed Multiplier". That means users can
not adjust the CPU Ratio but only change CPU FSB clock to achieve over-clocking.
(Users do the over- clocking at their own risk!)

Note:With CPU speed changing rapidly, there might be faster CPU on the market
by the time you received this installation guide. This table is kindly for your
references only.
Tip: When you fail to over-clock, you could:
Clear CMOS (JP14) to restore the default setting.
After turning power on, press “Home” immediately until the screen
appears.
