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 is overclocked. Normal operation depends on the overclocking capac-
ity 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 CPU and CPU Cooler
Install the CPU
Locate the alignment keys on the motherboard CPU socket and the notches on the CPU.
Read the following guidelines before you begin to install the CPU :
■ Make sure that the motherboard supports the CPU.
■ Always turn off the computer and unplug the power cord from the power supply before
installing the CPU to prevent hardware damage.
■ Locate the pin one of the CPU. The CPU cannot be inserted if oriented incorrectly. (Or
you may locate the notches on both sides of the CPU and alignment keys on the CPU
socket.)
■ Apply an even and thin layer of thermal grease on the surface of the CPU.
■ Do not turn on the computer if the CPU cooler is not installed, otherwise overheating
and damage of the CPU may occur.
■ Set the CPU host frequency in accordance with the CPU specications. It is not
recommended that the system bus frequency be set beyond hardware specications
since it does not meet the standard requirements for the peripherals. If you wish to
set the frequency beyond the standard specications, please do so according to your
hardware specications including the CPU, graphics card, memory, hard drive, etc.
Hyper-Threading Technology System Requirements:
(Go to Intel's website for more information about the Hyper-Threading Technology)
■ An Intel®CPU that supports HT Technology
■ A chipset that supports HT Technology
■ An operating system that is optimized for HT Technology
■ A BIOS that supports HT Technology and has it enabled

3. Lift the metal cover on the CPU
socket.
5. When CPU is properly seated,
replace the metal cover and push the
CPU socket lever back to its locked
position.
4. Check pin one marking (triangle)
with the pin one corner of the CPU
socket, align the CPU notches with
the socket alignment keys and gently
put the CPU onto the socket.
Before installing the CPU, make sure to turn off the computer and unplug the power
cord from the power outlet to prevent damage to the CPU.

Install the CPU Cooler
Follow the steps below to correctly install the CPU cooler on the motherboard. (The following
procedures use Foxconn cooler as the example.)
1. Apply and spread an even thermal
grease on the surface of CPU.
2. Place the four bolts of the CPU
cooler to the holes of the motherboard,
push them straight down from the top,
and the bolts will be fastened on the
motherboard. That's it.
3. Check the solder side of the
motherboard, the push pin should be
xed as depicted in the picture.

along with the direction of arrow
(counterclockwise).
2. Pull the push pin straight up.
3. Turning push pin clockwise to its
default position.
Use extreme care when removing the CPU cooler because the thermal grease may
adhere to the CPU. Inadequately removing the CPU cooler may damage the CPU.

This motherboard provides two DDR2 memory sockets and supports Dual Channel Technology.
When memory is installed, the BIOS will automatically check the memory in your system.
Two DDR2 memory sockets are divided into two channels :
Channel 0 : DIMM1
Channel 1 : DIMM2
The combinations of DIMM modules are :
DIMM1 DIMM2
Single Channel DS/SS -
Single Channel - DS/SS
Dual Channel DS/SS DS/SS
(DS : Double Side, SS : Single Side, - : No Memory)
It is recommended that memory of the same capacity, brand, speed, and chips be
used and please select dual channel rst to achieve optimum performance.
CAUTION
!
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.
CAUTION
!

Installing a 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.
Before installing a memory module, make sure to turn off the computer and unplug the
power cord from the power outlet to prevent damage to the memory module. Be sure
to install DDR2 DIMMs on this motherboard.

2-3 Install an Expansion Card
Follow the steps below to correctly install your expansion card in the expansion slot.
1. Locate an expansion slot that supports your card. Remove the metal slot cover from the chassis
back panel.
2. Align the card with the slot, and press down on the card until it is fully seated in the slot.
3. Make sure the metal contacts on the card are completely inserted into the slot.
4. Secure the card's metal bracket to the chassis back panel with a screw.
5. After installing all expansion cards, replace the chassis cover.
6. Turn on your computer. If necessary, go to BIOS Setup to make any required BIOS changes for
your expansion card(s).
7. Install the driver provided with the expansion card in your operating system.
Installing and Removing a PCI Express x16 Graphics Card :
• Installing a Graphics Card:
Gently insert the graphics card into the PCI Express x16 slot.
Make sure the graphics card is locked by the latch at the end of
the PCI Express x16 slot.
• Removing the Card:
Push the latch at the end of the PCI Express x16 slot to release
the card and then pull the card straight up from the slot.
