Installing the Motherboard
Safety Precautions
• Follow these safety precautions when installing the motherboard
• Wear a grounding strap attached to a grounded device to avoid damage from static electricity
• Discharge static electricity by touching the metal case of a safely
grounded object before working on the motherboard
• Leave components in the static-proof bags they came in
• Hold all circuit boards by the edges. Do not bend circuit boards
Choosing a Computer Case
There are many types of computer cases on the market. The motherboard complies
with the specifications for the Micro ATX system case. First, some features on the
motherboard are implemented by cabling connectors on the motherboard to indicators and switches on the system case. Make sure that your case supports all the
features required. Secondly, this motherboard supports two enhanced IDE drives.
Make sure that your case has sufficient power and space for all drives that you intend
to install.
Most cases have a choice of I/O templates in the rear panel. Make sure that the I/O
template in the case matches the I/O ports installed on the rear edge of the
motherboard.
This motherboard carries a Micro ATX form factor of 225 x 170 mm. Choose a case
that accommodates this form factor.
7
Installing the Motherboard in a Case
Refer to the following illustration and instructions for installing the motherboard in
a case.
Most system cases have mounting brackets installed in the case, which correspond
the holes in the motherboard. Place the motherboard over the mounting brackets
and secure the motherboard onto the mounting brackets with screws.
Ensure that your case has an I/O template that supports the I/O ports and expansion
slots on your motherboard.
Installing the Motherboard
8
Do not over-tighten the screws as this can stress the motherboard.
Checking Jumper Settings
This section explains how to set jumpers for correct configuration of the motherboard.
Setting Jumpers
Use the motherboard jumpers to set system configuration options. Jumpers with
more than one pin are numbered. When setting the jumpers, ensure that the jumper
caps are placed on the correct pins.
The illustrations show a 2-pin jumper.
When the jumper cap is placed on both
pins, the jumper is SHORT. If you remove the jumper cap, or place the jumper
cap on just one pin, the jumper is OPEN.
This illustration shows a 3-pin jumper.
Pins 1 and 2 are SHORT.

Installing Hardware
Installing the Processor
Caution: When installing a CPU heatsink and cooling fan make sure
that you DO NOT scratch the motherboard or any of the surfacemount resistors with the clip of the cooling fan. If the clip of the cooling
fan scrapes across the motherboard, you may cause serious damage
to the motherboard or its components.
On most motherboards, there are small surface-mount resistors near
the processor socket, which may be damaged if the cooling fan is
carelessly installed.
Avoid using cooling fans with sharp edges on the fan casing and the
clips. Also, install the cooling fan in a well-lit work area so that you
can clearly see the motherboard and processor socket.
Before installing the Processor
This motherboard automatically determines the CPU clock frequency and system bus
frequency for the processor. You may be able to change the settings in the system
Setup Utility. We strongly recommend that you do not over-clock processors or
other components to run faster than their rated speed.
Warning:
1. Over-clocking components can adversely affect the reliability of the
system and introduce errors into your system. Over-clocking can permanently damage the motherboard by generating excess heat in components that are run beyond the rated limits.
2. Always remove the AC power by unplugging the power cord from
the power outlet before installing or removing the motherboard or
other hardware components.
This motherboard has an LGA775 socket. When choosing a processor, consider the
performance requirements of the system. Performance is based on the processor
design, the clock speed and system bus frequency of the processor, and the quantity
of internal cache memory and external cache memory.
Installing the Motherboard
CPU Installation Procedure
The following illustration shows CPU installation components.
A. Read and follow the instructions shown
on the sticker on the CPU cap.
B. Unload the cap
· Use thumb & forefinger to hold the
lifting tab of the cap.
· Lift the cap up and remove the cap
completely from the socket.
C. Open the load plate
· Use thumb & forefinger to hold the
hook of the lever, pushing down and
pulling aside unlock it.
· Lift up the lever.
· Use thumb to open the load plate. Be
careful not to touch the contacts.
D. Install the CPU on the socket
· Orientate CPU package to the socket.
Make sure you match triangle marker
to pin 1 location.
E. Close the load plate
· Slightly push down the load plate onto
the tongue side, and hook the lever.
· CPU is locked completely.
11
F. Apply thermal grease on top of the CPU.
G. Fasten the cooling fan supporting base
onto the CPU socket on the motherboard.
H. Make sure the CPU fan is plugged to the
CPU fan connector. Please refer to the
CPU cooling fan user’s manual for more
detail installation procedure.
1. To achieve better airflow rates and heat dissipation, we suggest
that you use a high quality fan with 3800 rpm at least. CPU fan and
heatsink installation procedures may vary with the type of CPU fan/
heatsink supplied. The form and size of fan/heatsink may also vary.
2. DO NOT remove the CPU cap from the socket before installing a
CPU.
3. Return Material Authorization (RMA) requests will be accepted
only if the motherboard comes with the cap on the LGA775 socket.

Installing Memory Modules
This motherboard accommodates two memory modules. It can support two 240-pin
DDR2 800. The total memory capacity is 8 GB.
DDR2 SDRAM memory module table
Memory module Memory Bus
DDR2 800 400 MHz
You must install at least one module in any of the two slots. The total memory
capacity is up to 8 GB.
Do not remove any memory module from its antistatic packaging until
you are ready to install it on the motherboard. Handle the modules
only by their edges. Do not touch the components or metal parts.
Always wear a grounding strap when you handle the modules.
Installation Procedure
Refer to the following to install the memory modules.
1 This motherboard supports unbuffered DDR2 SDRAM .
2 Push the latches on each side of the DIMM slot down.
3 Align the memory module with the slot. The DIMM slots are keyed with
notches and the DIMMs are keyed with cutouts so that they can only be
installed correctly.
4 Check that the cutouts on the DIMM module edge connector match the
notches in the DIMM slot.
5 Install the DIMM module into the slot and press it firmly down until it
seats correctly. The slot latches are levered upwards and latch on to
the edges of the DIMM.
6 Install any remaining DIMM modules.

Expansion Slots
Installing Add-on Cards
The slots on this motherboard are designed to hold expansion cards and connect
them to the system bus. Expansion slots are a means of adding or enhancing the
motherboard’s features and capabilities. With these efficient facilities, you can increase the motherboard’s capabilities by adding hardware that performs tasks that are
not part of the basic system.
PCIEX16 Slot
PCIEX1 Slot
PCI Slot
The PCI Express slot is used to install an external PCI Express
graphics card that is fully compliant to the PCI Express Gen 1.
The PCI Express x1 slot is fully compliant to the PCI Express Base
Specification revision 1.0.
This motherboard is equipped with one standard PCI slot. PCI stands
for Peripheral Component Interconnect and is a bus standard for
expansion cards, which for the most part, is a supplement of the
older ISA bus standard. The PCI slot on this board is PCI v2.3
compliant.
Before installing an add-on card, check the documentation for the card
carefully. If the card is not Plug and Play, you may have to manually
configure the card before installation.
Installing the Motherboard
Follow these instructions to install an add-on card:
1 Remove a blanking plate from the system case corresponding to the
slot you are going to use.
2 Install the edge connector of the add-on card into the expansion slot.
Ensure that the edge connector is correctly seated in the slot.
3 Secure the metal bracket of the card to the system case with a screw.
1. For some add-on cards, for example graphics adapters and network
adapters, you have to install drivers and software before you can begin using
the add-on card.
2. The onboard PCI interface does not support 64-bit SCSI cards.
