FCC-B Radio Frequency Interference Statement

This equipment has been tested and found to comply with the limits for a class
B digital device, pursuant to part 15 of the FCC rules. These limits are designed
to provide reasonable protection against harmful interference when the equip­ment is operated in a commercial environment. This equipment generates, uses
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
comply with the emission limits.

PC Alert™ 4

The PC AlertTM 4 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:

ö monitor CPU & system temperatures
ö monitor fan speeds
ö monitor system voltages

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 the condition returns to the normal status.

Users can use the Adjusting Keys to change the minimum and maximum
threshold of each item for the system to send out a warning message. Click
Temperature to select the temperature modes of either Fahrenheit (oF) or Cel-
sius (oC). The PC Alert4 icon on the Status Area will show the current CPU
temperature.

CPU Core Speed Derivation Procedure

If CPU Clock = 100MHz

Core/Bus ratio = 17

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

= 100MHz x 17
= 1.7 GHz

The mainboard supports Intel® Pentium® 4 Prescott & Northwood 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 . (For the latest information

about CPU, please visit http://www.msi.com.tw/program/products/mainboard/mbd/
pro_mbd_cpu_support.php )

MSI Reminds Y ou...

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 90­degree 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:

2. Position the heatsink onto the reten­tion 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 reten­tion mechanism.

4. Press the two levers down to fasten
the fan. Each lever can be pressed
down in only ONE direction.

Memory

The mainboard provides two 184-pin unbuffered DDR266/DDR333/
DDR400 DDR SDRAM, and supports the memory size up to 2GB without ECC.
To operate properly, at least one DIMM module must be installed.

(For the updated supporting memory modules, please visit http://www.msi.com.

DDR DIMM Slots

(DDR 1~2)

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.

MSI Reminds Y ou...

For Micron MT46V32M8TG-5B DDR400 memory module,
please be sure to install 2 dimms to avoid the incompatibility
issue.

MS-6540G Micro ATX Mainboard

DDR 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 double-sided
modules to meet your own needs.

Memory modules can be installed in any combination as follows:

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.

You can barely see the golden finger if the module is properly
inserted in the socket.

Power Supply

The mainboard supports ATX power supply for the power system. Before
inserting the power supply connector, always make sure that all components
are installed properly to ensure that no damage will be caused.

A TX 20-Pin Power Connector: CONN1

This connector allows you to connect to an ATX power supply. To
connect to the ATX power supply, make sure the plug of the power supply is
inserted in the proper orientation and the pins are aligned. Then push down
the power supply firmly into the connector.
