Hardware Setup

Central Processing Unit: CPU

The mainboard supports AMD® Athlon64/ Sempron processor. The mainboard uses a
CPU socket called Socket-754 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 have the heat sink and cooling fan,
contact your dealer to purchase and install them before turning on the computer.

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 754

1. Please turn off the power and

unplug the power cord before
installing the CPU.

Open Lever

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 as picture
shown. 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 AMD Athlon64 CPU Cooler Set

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 have the

heat sink and cooling fan, contact your dealer to purchase and install them before
turning on the computer.

1.Position the cooling set onto the
retention mechanism. Hook one
end of the clip to hook first.

4.Fasten down the lever.

2.Press down the other end of the
clip to fasten the cooling set on
the top of the retention
mechanism.

3.Locate the Fix Lever, Safety Hook
and the Fixed Bolt. Lift up the in­tensive fixed lever.

5.Make sure the safety hook
completely clasps the fixed
bolt of the retention
mechanism.

6. Connect the fan power cable
from the mounted fan to the
CPUFAN1 connector on the
board

MSI Reminds You...

While disconnecting the Safety
Hook from the fixed bolt, it is
necessary to keep an eye on
your fingers, because once the
Safety Hook is disconnected
from the fixed bolt, the fixed
lever will spring back instantly.

Memory

The mainboard provides two slots for 184-pin DDR SDRAM DIMM (Double In-Line
Memory Module) modules and supports up to 2GB memory size. You can install
PC3200/DDR400, PC2700/DDR333 & PC2100/DDR266 modules on the DDR DIMM slots
(DDR 1~2).
For the updated supporting memory modules, please visit http://www.msi.com.tw/

DDR DIMM Slots

(DIMM1~2)

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. High memory bandwidth makes DDR an ideal solution
for high performance PC, workstations and servers.

E-2-6

Hardware Setup

DDR 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 double-sided modules to meet your
own needs.
Memory modules can be installed in any combination as follows:

Slot Memory Module Total Memory

DIMM 1

S/D 64MB~1GB
(Bank 0 & 1)
DIMM 2

S/D 64MB~1GB
(Bank 2 & 3)

Maximum System Memory Supported

S: Single Side D: Double Side

64MB~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.

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.

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

temperature of CPU reaches 100oC, or the low voltage occurs during
booting up. Please follow the instructions below for this issue:

1. The power LED will blink continously. You should unplug the power
cord or turn off the power switch.

2.After the power LED stop blinking, plug on the power cord or turn on
the power switch, then you can reboot your system again.
