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 Northwood & Prescott Celeron processor 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

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.

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.

5. Connect the fan power cable from the mounted fan to the 3-pin fan power connector on the

board.

Memory

The mainboard provides two 184-pin unbuffered DDR200/DDR266/DDR333 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.
