equipment off and on, the user is encouraged to try to correct the interference by one
or more of the measures listed below.

=Reorient or relocate the receiving antenna.
=Increase the separation between the equipment and receiver.
=Connec the equipment into an outlet on a circuit different from that to which the

receiver is connected.

=Consult the dealer or an experienced radio/television technician for help.

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

Microsoft’s Windows 2000 Service Pack 4 (SP4) is required. As
the end user cannot boot without SP4, a combination installation
CD must be created before attempting to install the operating sys­tem onto the bootable RAID volume.
To create the combination installation CD, please refer to the fol­lowing website:

Hardware Setup

Central Processing Unit: CPU

The mainboard supports AMD® Athlon64 processor. The mainboard uses a
CPU socket called Socket-939 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.

For the latest information about CPU, please visit http://www.msi.com.tw/pro­gram/products/mainboard/mbd/pro_mbd_cpu_support.php.

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.

CPU Installation Procedures for Socket 939

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 of the
CPU. The gold arrow should point
as shown in the picture. 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.

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

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.

MSI Reminds You...

Mainboard photos shown in this section are for demonstration of the
cooler installation for Socket 939 CPUs only. The appearance of
your mainboard may vary depending on the model you purchase.

1.Position the cooling set onto the re­tention mechanism.

Hook one end of the clip to hook
first, and then press down the other
end of the clip to fasten the cooling
set on the top of the retention
mechanism.

2.Locate the Fix Lever, Safety Hook
and the Fixed Bolt.

Lift up the intensive fixed lever.

3.Fasten down the lever.

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

Memory

The mainboard provides 4 slots for 184-pin DDR DIMM (Double In-Line Memory
Module) modules and supports the memory size up to 4GB. You can install DDR 333/
400 modules on the DDR DIMM slots (DIMM 1~4).

DIMM1~DIMM4

(from left to right)

DIMM Module Combination

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. Users may install memory modules of different type and
density on different-channel DDR DIMMs. However, memory modules of the same
type and density are required while using dual-channel DDR, or instability may
happen.

MSI Reminds You...

- The system operates dual channel ONLY when the DDR modules
are installed in accordance with the above-mentioned memory
population rules.

- In dual-channel mode, make sure that you install memory modules
of the same type and density on DDR DIMMs.

- To enable successful system boot-up, always insert the memory
modules into the Channel A slots (DIMM1 or DIMM3) first.

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.

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 24-Pin Power Connector: ATX1

This connector allows you to connect an ATX 24-pin power supply. To con­nect the ATX 24-pin 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.

You may use the 20-pin ATX power supply as you like. If
you’d like to use the 20-pin ATX power supply, please plug your
power supply along with pin 1 & pin 13 (refer to the image at the
right hand). There is also a foolproof design on pin 11, 12, 23 & 24
to avoid wrong installation.
