Chapter 2. Hardware
Setup
This chapter tells you how to install the CPU, memory
modules, and expansion cards, as well as how to setup the jump-
ers on the mainboard. Also, it provides the instructions on
connecting the peripheral devices, such as the mouse, keyboard,
etc.
While doing the installation, be careful in holding the com-
ponents and follow the installation procedures.

Hardware Setup
Central Processing Unit: CPU
The mainboard supports Intel®Pentium®4 Northwood/Prescott proc-
essor in the 478 pin package. The mainboard uses a CPU socket called PGA478
for easy CPU installation. When you are installing the CPU, make sure the
CPU has a heat sink and a cooling fan attached on the top to prevent
overheating. If you do not find the heat sink and cooling fan, contact your
dealer to purchase and install them before turning on the computer.
Example of CPU Core Speed Derivation Procedure
If CPU Clock = 133MHz
Core/Bus ratio = 23
then CPU core speed = Host Clock x Core/Bus ratio
= 133MHz x 23
= 3.06 GHz

1. Please turn off the power and
unplug the power cord before
installing the CPU.
2. Pull the lever sideways away
from the socket. Make sure
to raise the lever up to a 90-
degree angle.
3. Look for the cut edge. The cut
edge should point towards the
lever pivot. The CPU can only
fit in the correct orientation.
4. If the CPU is correctly
installed, the pins should be
completely embedded into the
socket and can not be seen.
Please note that any violation
of the correct installation pro-
cedures may cause permanent
damages to your mainboard.
5. Press the CPU down firmly into
the socket and close the lever.
As the CPU is likely to move
while the lever is being closed,
always close the lever with
your fingers pressing tightly
on top of the CPU to make sure
the CPU is properly and com-
pletely embedded into the
socket.

Installing the CPU Fan
As processor technology pushes to faster speeds and higher performance,
thermal management becomes increasingly important. To dissipate heat, you
need to attach the CPU cooling fan and heatsink on top of the CPU. Follow the
instructions below to install the Heatsink/Fan:
2. Position the heatsink onto the reten-
tion mechanism.
1. Locate the CPU and its retention
mechanism on the motherboard.
3. Mount the fan on top of the heatsink.
Press down the fan until its four clips
get wedged in the holes of the reten-
tion mechanism.
4. Press the two levers down to fasten
the fan. Each lever can be pressed
down in only ONE direction.

MSI Reminds You...
Overheating
Overheating will seriously damage the CPU and system, al-
ways make sure the cooling fan can work properly to protect
the CPU from overheating.
Replacing the CPU
While replacing the CPU, always turn off the ATX power supply
or unplug the power supply’s power cord from grounded outlet
first to ensure the safety of CPU.
Overclocking
This motherboard is designed to support overclocking.
However, please make sure your components are able to toler-
ate such abnormal setting, while doing overclocking. Any at-
tempt to operate beyond product specifications is not
recommended. We do not guarantee the damages or risks
caused by inadequate operation or beyond product
specifications.
5. Connect the fan power cable from the mounted fan to the 3-pin fan power connec-
tor on the board.
