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.

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.

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.

For the latest information about CPU, please visit http://www.msi.com.tw/

program/products/mainboard/mbd/pro_mbd_cpu_support.php.

CPU Core Speed Derivation Procedure

CPU Clock multiplied by Core/Bus ratio equals the CPU core speed.

For example:
If CPU Clock = 100MHz

Core/Bus ratio = 14

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

= 100MHz x 14
= 1.4 GHz

2-4

MS-7051G M-ATX Mainboard

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.

Hardware Setup

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...

Please apply some heat sink paste on top of CPU to dissipate the heat
more effectively.

MS-7051G M-ATX Mainboard

Memory

The mainboard provides 2 slots for 184-pin DDR SDRAM DIMM (Double In-Line Memory
Module) modules and supports the memory size up to 2GB. You can install DDR266/
333/400 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.

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.

2-7

Hardware Setup

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.

DIMM Module Combination

Install at least one DIMM module on the slots. You can install either single- or double­sided modules in any order to meet your own needs.

Memory modules can be installed in any combination as follows:

S: Single Side D: Double Side

Slot Memory Module T otal Memory

MS-7051G 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: JWR1

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.

MSI Reminds You...

1. These two connectors connect to the ATX power supply and have to
work together to ensure stable operation of the mainboard.

2. Power supply of 300 (and up) watt is highly recommended for system
stability.

The back panel provides one standard IEEE 1394 port. The standard IEEE 1394 port
connects to IEEE 1394 devices without external power. The IEEE 1394 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.

MS-7051G M-ATX Mainboard

The mainboard provides connectors to connect to FDD, IDE HDD, case, LAN, USB
Ports and CPU/System FAN.

Floppy Disk Drive Connector: FDD1

The mainboard provides a standard floppy disk drive connector that supports 360K,
720K, 1.2M, 1.44M and 2.88M floppy disk types.

Connectors

Fan Power Connectors: CPU_F AN1 & SYS_F AN1

The CPU_FAN1 (processor fan) and SYS_FAN1 (system fan 1) support system
cooling fan with +12V. It supports three-pin head connector. When connecting the
wire to the connectors, always take note that the red wire is the positive and should
be connected to the +12V, the black wire is Ground and should be connected to GND.
If the mainboard has a System Hardware Monitor chipset on-board, you must use a
specially designed fan with speed sensor to take advantage of the CPU fan control.

MSI Reminds You...

1. Always consult the vendors for proper CPU cooling fan.

2. Please refer to the recommend CPU fans at AMD® official website.

Hardware Setup

Hard Disk Connectors: IDE1 & IDE2

The mainboard has a 32-bit Enhanced PCI IDE and Ultra DMA 33/66/100/133 controller
that provides PIO mode 0~4, Bus Master, and Ultra DMA 33/66/100/133 function. You
can connect up to four hard disk drives, CD-ROM, 120MB Floppy (reserved for future
BIOS) and other devices.

IDE1 (Primary IDE Connector)
The first hard drive should always be connected to IDE1. IDE1 can connect a Master

and a Slave drive. You must configure second hard drive to Slave mode by setting the
jumper accordingly.

IDE2 (Secondary IDE Connector)
IDE2 can also connect a Master and a Slave drive.

MSI Reminds You...

If you install two hard disks on cable, you must configure the second
drive to Slave mode by setting its jumper. Refer to the hard disk
documentation supplied by hard disk vendors for jumper setting
instructions.
