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 AMD ® AthlonTM/AthlonTM XP/DuronTM processor in the 462 pin package. The
mainboard uses a CPU socket called Socket A 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 = 100MHz
Core/Bus ratio = 14
then CPU core speed = Host Clock x Core/Bus ratio
= 100MHz x 14
=1.4GHz

CPU Installation Procedures for Socket 462
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
The following instructions will guide you through the heat sink installation procedures. Please consult
your agent for the proper CPU cooler set.
1. Position your CPU cooler set onto the CPU.
2. Use one end of the clip to hook the latch of the CPU sliding plate.
3. Hook the other latch to fix the cooling fan set. You may need a screw drive to press down the
other side of the clip.
4. Connect the fan to the power supply connector provided on your mainboard.

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 DDR266/DDR333/DDR400 (for KM400A only) 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.
