Hardware Setup
This chapter tells you how to install the CPU, memory modules, and expansion cards, as well as
how to setup the jumpers on the mainboard. It also provides the instructions on connecting the
peripheral devices, such as the mouse, keyboard, etc. While doing the installation, be careful in
holding the components and follow the installation procedures.
Central Processing Unit: CPU
The mainboard supports Intel Pentium 4 Willamette / Northwood / Prescott / Prescott Celeron
processor (FSB 400MHz/533MHz) 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. (For the latest information about CPU, please visit
http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_cpu_support.php )
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
=3.06GHz

CPU Installation Procedures for Socket 478
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 gold arrow. The gold arrow 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 procedures
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 completely 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:
1. Locate the CPU and its retention mechanism on the motherboard.
2. Position the heatsink onto the retention mechanism.
3. Mount the fan on top of the heatsink. Press down the fan until its four clips get wedged in
the holes of the retention mechanism.
4. Press the two levers down to fasten the fan. Each lever can be pressed down in only ONE
direction.

6
5. Connect the fan power cable from the mounted fan to the 3-pin fan power connector on
the board.
MSI Reminds You...
Overheating…
Overheating will seriously damage the CPU and system, always 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.
Memory
The mainboard provides two 184-pin unbuffered DDR200/DDR266/DDR333 DDR SDRAM, and
supports the memory size up to 2GB. To operate properly, at least one DIMM module must be
installed. (For the updated supporting memory modules, please visit
http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_trp_list.php )
Install at least one DIMM module on the slots. Memory modules can be installed on the slots in
any order. You can install either single- or double-sided modules to meet your own needs.
Installing DDR Modules:
1. The DDR DIMM has only one notch on the center of module. The module will only fit in the
right orientation.
2. Insert the DIMM memory module vertically into the DIMM slot. Then push it in until the
golden finger on the memory module is deeply inserted in the socket.
3. The plastic clip at each side of the DIMM slot will automatically close.
