and can radiate radio frequency energy and, if not installed and used in accor­dance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to
cause harmful interference, in which case the user will be required to correct
the interference at his own expense.

Notice 1

The changes or modifications not expressly approved by the party respon­sible for compliance could void the user’s authority to operate the equipment.

Notice 2

Shielded interface cables and A.C. power cord, if any, must be used in order to

The PC AlertTM III is a utility you can find in the CD-ROM disk. The
utility is just like your PC doctor that can de­tect the following PC hardware status during
real time operation:

* monitor CPU & system temperatures
* monitor fan speed(s)
* monitor system voltage
* monitor chassis intrusion

If one of the items above is abnormal,
the program main screen will be immediately
shown on the screen, with the abnormal item
highlighted in red. This will continue to be
shown until user disables the warning.

Note: Items shown on PC Alert III vary depending on your system’s

status.

Fuzzy Logic™ 4

The Fuzzy Logic™ 4 utility is a user friendly tool that allows users to
view and adjust the current system status. To overclock the CPU FSB (Front
Side Bus) frequency under the Windows operating system, click FSB and use
the right and left arrow keys to select the desired FSB, and then click Apply to
apply the new setup value. To enable the system running at the specified FSB
every time when you click Turbo, click Save to save the desired FSB first. If
you want to know the maximal CPU overclocking value, click Auto to start
testing. The CPU FSB will automatically increase the testing value until the PC
reboots. After rebooting, click Turbo to apply the test result. Click Default to
restore the default values.

MSI DVD (5.1 Channel)

The motherboard comes with MSI DVD application which supports 5.1
channel (6-channel audio) operation. The accompanying MSI DVD is a conve­nient tool to meet increasing demands for home entertainment.

Note: MSI DVD supports Dolby Digital format only. To view DTS-

formatted video, you should convert it to Dolby Digital format first.

To play DVD with 6-channel audio output, you must configure both the
MSI DVD application and the audio codec’s software utility. Otherwise, the 6­channel audio function will not work properly. For information on how to
select 6-channel mode in the audio software utility, refer to Appendix. Using 4-
or 6-Channel Audio Function.

Follow the procedures below to enable 6-channel support with MSI DVD:

1. Click on this button from the control panel of MSI DVD.

2. Click the Audio tab.

3. Select 6 speaker mode (5.1 channel).

CPU Thermal Protection

Aimed to prevent the CPU from overheating, MSI has developed a CPU
Thermal Protection mechanism for AMD Athlon XP CPU platform. This CPU
Thermal Protection mechanism works on a thermal signal sensor. If the mecha­nism senses an abnormal temperature rise, it will automatically shut down the
system and the CPU temperature will then drop down and resume normal. With
this unique feature, users can better protect their CPU. Please note that this
feature is for AMD Athlon XP CPU only.

Hardware Setup

This chapter provides you with the information about hardware setup
procedures. While doing the installation, be careful in holding the compo­nents and follow the installation procedures. For some components, if you
install in the wrong orientation, the components will not work properly.

Use a grounded wrist strap before handling computer components. Static
electricity may damage the components.

Central Processing Unit: CPU

The mainboard supports AMD® Athlon™, Athlon™ XP and Duron™
processors 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.

CPU Installation Procedures

1. Pull the lever sideways away

from the socket. Then, raise
the lever up to a 90-degree
angle.

2. Look for the cut edge. The

cut edge should point to­wards the lever pivot. The
CPU will only fit in the correct
orientation.

3. Hold the CPU down firmly, and

then close the lever to com­plete the installation.

WARNING!

Overheating will seriously damage the CPU and system,
always make sure the cooling fan can work properly to
protect the CPU from overheating.

Hardware Setup

WARNING! Thermal Issue for CPU

As processor technology pushes to faster speeds and higher performance,
thermal management becomes increasingly crucial when building computer
systems. Maintaining the proper thermal environment is key to reliable
operation. As such, the processor must be maintained in the specified thermal
requirements.

AMD Athlon™/Duron™/Athlon™ XP processor with a speed of 600MHz
and above requires LARGER heatsink and fan. You also need to add thermal
grease between the CPU and heatsink to improve heat dissipation. Then, make
sure that the CPU and heatsink are securely fastened and in good contact with
each other. These are needed to prevent damaging the processor and ensur­ing reliable operation. If you want to get more information on the proper
cooling, you can visit AMD’s website for reference.

2-3

Chapter 2

CPU Core Speed Derivation Procedure

If CPU Clock = 100MHz

Core/Bus ratio = 7

then CPU core speed = Host Clock x Core/Bus ratio

= 100MHz x 7
= 700MHz

CPU Clock Frequency Selection through BIOS

The hardware configuration for CPU clock frequency of the motherboard
is set to 100MHz by default. Therefore, to make a 133MHz CPU run at 133MHz
when it is installed on the board, you have to adjust the CPU clock frequency
in the BIOS setup utility.

To set the clock frequency for the installed CPU, refer to Frequency/
Voltage Control in Chapter 3. BIOS Setup.

WARNING!

Replacing 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 tolerate such abnormal setting, while doing
overclocking. Any attempt to operate beyond prod­uct specifications is not recommended. We do not

guarantee the damages or risks caused by inadequate
operation or beyond product specifications.

Hardware Setup

Memory

The mainboard provides 3 sockets for 184-pin DDR SDRAM DIMM
(Double In-Line Memory Module) modules and supports the memory size up
to 3GB. Y ou can install PC2700/DDR333, PC2100/DDR266 or PC1600/DDR200
modules on the DDR DIMM slots (DIMM 1~3).

DDR DIMM Slots

(DIMM 1~3)

Introduction to DDR SDRAM

DDR (Double Data Rate) SDRAM is similar to conventional SDRAM,
but doubles the rate by transferring data twice per cycle. It uses 2.5 volts as
opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM mod­ules rather than 168-pin DIMM modules used by SDR SDRAM. High memory
bandwidth makes DDR an ideal solution for high performance PC, worksta­tions and servers.

2-5

Chapter 2

DIMM Module Combination

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 double­sided modules to meet your own needs.

Memory modules can be installed in any combination as follows:

Slot Memory Module Total Memory

DIMM 1
(Bank 0 & 1)
DIMM 2
(Bank 2 & 3)
DIMM 3
(Bank 4 & 5)

S/D 64MB~1GB

64MB~3GB

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.

TIP: You can barely see the golden finger if the module is properly

inserted in the socket.
