Hardware Setup

Central Processing Unit: CPU

The mainboard supports Intel® Pentium® 4/Celeron Northwood/Prescott 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

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 cut edge. The cut
edge 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.

retention mechanism

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.

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

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

MSI Reminds You...

If your Intel Pentium 4 proces­sor supports 3.0GHz (and

up), please be sure to use a
multi-direction fan to make the heatsink
exhausts air towards the voltage regu­lators on the board easier. Multi-direc­tion fan has better performance in CPU
overheating.

2-5

MS-7037 M-ATX Mainboard

Memory

The mainboard provides 2 slots for 184-pin DDR SDRAM DIMM (Double In­Line Memory Module) modules and supports the memory size up to 1GB. You can
install DDR400/DDR333/DDR266 modules on the DDR DIMM slots (DDR 1~2).

For the updated supporting memory modules, please visit http://www.msi.
com.tw/program/products/mainboard/mbd/pro_mbd_trp_list.php.

DIMM1 DIMM2

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.

2-6

Hardware Setup

DDR Population Rules

Install at least one DIMM module on the slots. Each DIMM slot supports up to a
maximum size of 1GB. Users can install either single- or double-sided modules to
meet their own needs. Also, since this mainboard supports dual-channel function,
please note that DIMM1 (Channel A, in green) working together with DIMM2
(Channel B, in purple) will fuction as dual-channel.In order to have better
performance, it is recommended to install memory modules of the same type and
density on DDR DIMMs.

Please refer to the following table for detailed DDR population:

DIMM1 (Ch A) DIMM2 (Ch A) System Density

128MB~1GB 128MB~1GB

128MB~1GB 128MB~1GB

128MB~1GB * 128MB~1GB * 256MB~2GB

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.

MSI Reminds You...

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

inserted in the socket.

MS-7037 M-ATX Mainboard

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.

ATX 20-Pin Power Connector: ATX1

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.

Hardware Setup

IEEE1394 Port (Optional)

The mainboard provides one standard IEEE1394 port. The
standard IEEE1394 port connects to IEEE1394 devices without
external power. The IEEE1394 high-speed serial bus
complements USB by providing enhanced PC connectivity for a
wide range of devices, including consumer electronics audio/
video (A/V) appliances, storage peripherals, other PCs, and
portable devices.

VGA Connector (Optional, for 865G/GV)

The mainboard provides a DB 15-pin female connector to connect a VGA monitor.
