Installation Precautions
Please carefully read the following procedures to install your computer :
■ It is suggested to select high-quality, certied fans in order to avoid damage
to the motherboard and CPU due to high temperature. Never turn on the
computer if the CPU fan is not properly installed.
■ We cannot guarantee that your system can operate normally when your
CPU/Memory is overclocked. Normal operation depends on the overclocking
capacity of your device.
■ If there is any, when connecting USB, audio, 1394a, RS232 COM, IrDA or
S/PDIF cables to the internal connectors on the motherboard, make sure
their pinouts are matching with the connectors on the motherboard. Incorrect
connections might damage the motherboard.
■ When handling the motherboard, avoid touching any metal leads or connec-
tors.
■ If there is a PCI Express x16 graphics card installed in your system, we
recommend using a 24-pin ATX power supply to get the best performance.
■ Before turning on the power, please make sure the power supply AC input
voltage setting has been congured to the local standard.
■ To prevent damage to the motherboard, do not allow screws to come in contact
with the motherboard circuit or its components. Also, make sure there are no
leftover screws or metal components placed on the motherboard or within the
computer casing.
■ If you are uncertain about any installation steps or have a problem related to
the use of the product, please consult a certied computer technician.
CAUTION
!
■ Electrostatic discharge (ESD) is the sudden and momentary electric current
that ows between two objects at different electrical potentials. Normally it
comes out as a spark which will quickly damage your electronic equipment.
Please wear an electrostatic discharge (ESD) wrist strap when handling
components such as a motherboard, CPU or memory.
■ Ensure that the DC power supply is turned off before installing or removing
CPU, memory, expansion cards or other peripherals. It is recommended to
unplug the AC power cord from the power supply outlet. Failure to unplug
the power supply cord may result in serious damage to your system.

2-1 Install the Memory
If you take a look at front side of memory module, it has asymmetric pin counts on both sides
separated by a notch in the middle, so it can only t in one direction. Follow the steps below to
correctly install your memory modules into the sockets.
Step 1:
Spread the clips at both ends of the memory socket.
Place the memory module onto the socket, then put
your ngers on top edge of the module, and push
it down rmly and seat it vertically into the memory
socket.
Step 2:
The clips at both ends of the socket will snap into
place when the memory module is securely inserted.
112-Pin128-Pin
Read the following guidelines before you begin to install the memory :
■ Make sure that the motherboard supports the memory. It is recommended that memory
of the same capacity, brand, speed, and chips be used.
■ Always turn off the computer and unplug the power cord from the power outlet before
installing the memory to prevent hardware damage.
■ Memory modules have a foolproof design. A memory module can be installed in only
one direction. If you are unable to insert the memory, switch the direction.
■ Be sure to install DDR2 DIMMs on this motherboard.

Power Connectors
This motherboard uses an ATX power supply. In order not to damage any device, make sure all the
devices have been installed properly before applying the power supply.
24-pin ATX power connector : PWR2
PWR2 is the ATX power supply connector. Make sure that the power supply cable and pins are
properly aligned with the connector on the motherboard. Firmly plug the power supply cable into the
connector and make sure it is secure.
4-pin ATX 12 V Power Connector : PWR1
Connect the 4-pin ATX 12V power supply to PWR1 and provides power to the CPU.

USB Connectors : F_USB1/2
In addition to the four USB ports on the rear panel, this
product also provides two 10-pin USB headers on its
motherboard. By connecting through USB cables with
them, user can quickly expand another four USB ports
on the front panel.
S/PDIF OUT Connector : SPDIF_OUT1
The connector is used for S/PDIF output.
TPM Connector : TPM1
The TPM (Trusted Platform Module) provides the ability
to the PC to run applications more secure and to make
transactions and communication more trustworthy. To
utilize this function, you should purchase additional
device and install it.
COM Connector : COM2
This motherboard supports one serial RS232 COM port
for legacy compatibility. User must purchase another
RS232 cable with a 9-pin D-sub connector at one end
to connect with the external RS232 device and another
end with 10-pin female connector to connect with COM2
connector in the motherboard.

Front Panel Connector : FP1
This motherboard includes one connector for connecting the
front panel switch and LED Indicators.
Hard Disk LED Connector (HDD-LED)
Connect to the chassis front panel IDE indicator LED. It
indicates the active status of the hard disks. This 2-pin
connector is directional with +/- sign.
Reset Switch (RESET-SW)
Attach the connector to the Reset switch on the front
panel of the case; the system will restart when the switch
is pressed.
Power LED Connector (PWR-LED)
Connect to the power LED indicator on the front panel of
the chassis. The Power LED indicates the system’s status.
When the system is in operation (S0 status), the LED is
on. When the system gets into sleep mode (S1) , the LED
is blinking; When the system is in S3/S4 sleep state or
power off mode (S5), the LED is off. This 2-pin connector
is directional with +/- sign.
Power Switch Connector (PWR-SW)
Connect to the power button on the front panel of the
chassis. Push this switch allows the system to be turned
on and off rather than using the power supply button.
Serial ATA Connectors : SATA_1/2
The Serial ATA connector is used to connect with SATA Hard
Disk or CD devices which supporting this feature. The current
Serial ATA II interface allows up to 300MB/s data transfer
rate.
IrDA Connector : IR/CIR1
This connector supports infrared wireless transmitting and
receiving device.

2-3 Jumpers
For some features needed, users can change the jumper settings on this motherboard to modify them.
This section explains how to use the various functions of this motherboard by changing the jumper
settings. Users should read the following content carefully prior to modifying any jumper setting.
Description of Jumpers
1. For any jumper on this motherboard, Pin 1 can be identied by the bold silkscreen next to it.
However, in this manual, Pin 1 is simply labeled as “1”.
2. The following table explains different types of the jumper settings. "Closed" means placing a jumper
cap on the two pins to temporarily short them. The shorting can also be done by touching two
pins by a screwdriver for a few seconds, but using jumper cap is recommended. It can prevent
hazardous ESD (Electrical Static Discharge) problem.
Clear CMOS Jumper: CLR_CMOS
The motherboard uses CMOS RAM to store the basic hardware information (such as BIOS data,
date, time information, hardware password...etc.). Clear CMOS data is the fast way to go back to
factory default when the BIOS settings were mistakenly modied.
The steps to clear CMOS data are :
1. Turn off the computer, unplug the power cord from the power outlet.
2. Remove jumper cap from pins 2-3, put it onto pins 1-2 to short them. This will clear CMOS
data.
3. Return the setting to its original with pins 2-3 closed.
4. Plug in the power cord to your computer and turn it on.
5. Go to BIOS Setup to congure new system as described in next chapter.
