Static Electricity Precautions
1. Don’t take this motherboard and components out of their original static-
proof package until you are ready to install them.
2. While installing, please wear a grounded wrist strap if possible. If you
don’t have a wrist strap, discharge static electricity by touching the bare
metal of the system chassis.
3. Carefully hold this motherboard by its edges. Do not touch those
components unless it is absolutely necessary. Put this motherboard on
the top of static-protection package with component side facing up
whileinstalling.
Pre-Installation Inspection
1. Inspect this motherboard whether there are any damages to components
and connectors on the board.
2. If you suspect this motherboard has been damaged, do not connect
power to the system. Contact your motherboard vendor about those
damages.

Motherboard User’s Guide
Installing the Processor
This motherboard has a LGA775 socket for the latest Intel Pentium 4/Celeron
processors. 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.
CPU Installation Procedure
Follow these instructions to install the CPU:
A. 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.
B. 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.

Chapter 2: Motherboard Installation
C. Install the CPU on the socket
•Orientate CPU package to the socket.
Make sure you match triangle marker
to pin 1 location.
D. Close the load plate
•Slightly push down the load plate onto
the tongue side, and hook the lever.
•CPU is locked completely.
E. Apply thermal grease on top of the CPU.
F. Fasten the cooling fan supporting base
onto the CPU socket on the
motherboard.
G. 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.
Note1: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.
Note2:The fan connector supports the CPU cooling fan of1.1A~2.2A (26.4W
max.) at +12V.
Installing Memory Modules
This motherboard accommodates four memory modules, which are two 184-pin
2.5V DIMM3-4 sockets (Dual Inline Memory Module) for unbuffered DDR400
memory modules (Double Data Rate SDRAM) and the other two 240-pin 1.8V
DIMM1-2 sockets (Dual Inline Memory Module) for unbuffered DDR2 533/
DDR400 memory modules (Double Data Rate SDRAM). DDR SDRAM is a
type of SDRAM that supports data transfers on both edges of each clock cycle
(the rising and falling edges), effectively doubling the memory chip’s data
throughput. You must install at least one module in any of the four slots. Each
module can be installed with 256 MB to 1 GB of memory; total memory
capacity is 2 GB.

12
Motherboard User’s Guide
Note1: Please be noted you can NOT use DIMM1-2(DDR2 533/DDR400) and
DIMM3-4(DDR400) simultaneously. Only use either DDR2(533/400) or
DDR(400) memory modules!
Note2: 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.
Memory Module Installation Procedure
These modules can be installed with up to 2 GB system memory. Refer to the
following to install the memory module.
1. Push down the latches on both sides of the DIMM socket.
2. Align the memory module with the socket. There is a notch on the
DIMM socket that you can install the DIMM module in the correct
direction. Match the cutout on the DIMM module with the notch on
the DIMM socket.
3. Install the DIMM module into the socket and press it firmly down
until it is seated correctly. The socket latches are levered upwards and
latch on to the edges of the DIMM.
4. Install any remaining DIMM modules.

Jumper Settings
Connecting two pins with a jumper cap is SHORT; removing a jumper cap from
these pins, OPEN.
JP1: Clear CMOS Jumper
Use this jumper to clear the contents of the CMOS memory. You may need to
clear the CMOS memory if the settings in the Setup Utility are incorrect and
prevent your motherboard from operating. To clear the CMOS memory,
disconnect all the power cables from the motherboard and then move the jumper
cap into the CLEAR setting for a few seconds.
Note: To avoid the system unstability after clearing CMOS, we recommend
users to enter the main BIOS setting page to “Load Optimal De-faults”
and then “Save Changes and Exit”.

cooling fan to the CHS_FAN1 fan power connector on the motherboard.
Connect the Northbridge cooling fan connector to NB_FAN1.
Connect the case switches and indicator LEDs to the PANEL1 header. Please
refer to the following list of the PANEL1 pin assignments.
Install the Motherboard
Install the motherboard in a system chassis (case). The board is a Micro ATX
size motherboard. You can install this motherboard in an ATX case. Make sure
your case has an I/O cover plate matching the ports on this motherboard.

picture shows, the latch of power cable
falls on the left side of the PWR1
connector latch.
Users please note that when installing 24-
pin power cable, the latches of power
cable and the PWR1 connector match
perfectly.

20-pinpowercable
Note: Users please note that the 20-pin and 24-pin power cables can both be
connected to the PWR1 connector. While connceting the 20-pin power
cable, just align the 20-pin power cable with the pin 1 of the PWR1
connector. However, using 20-pin power cable may cause the system
the unbootable or unstable problem because of insufficient electricity.
The minimum recommended power is 300W for a fully-configured
system.
