or more of the measures listed below.

=Reorient or relocate the receiving antenna.
=Increase the separation between the equipment and receiver.
=Connect 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

MSI Reminds You...

To create a bootable RAID volume for a Windows 2000 environment,
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 X2/ Athlon64 FX/ Athlon64 processors.
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.

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.

CPU Installation Procedures for Socket 939

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 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.

Sliding

Plate

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 Socket 939 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 SDRAM DIMM (Double In-Line
Memory Module) modules and supports the memory size up to 4GB. You can install
DDR266/333/400 modules on the DDR DIMM slots (DIMM1~4).

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.

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. Please note that each DIMM can work respectively for

single-channel DDR, but there are some rules while using dual-channel
DDR (Please refer to the suggested DDR population table below). Users may install

memory modules of different type and density on different-channel DDR DIMMs.
However, the same type and density memory modules are necessary while
using dual-channel DDR, or instability may happen. Please refer to the following table
for detailed dual-channel DDR. Other combination not listed below will function as
single-channel DDR.

MSI Reminds You...

-Dual-channel DDR works ONLY in the 3 combinations listed in
the table shown in the previous page.

-Please select the identical memory modules to install on the dual
channel, and DO NOT install three memory modules on three
DIMMs, or it may cause some failure.

-Always insert the memory modules into the GREEN slots first, and
it is strongly recommended not to insert the memory modules into
the PURPLE slots while the GREEN slots are left empty.

- Due to the South Bridge resource deployment, the system density

will only be detected up to 3+GB (not full 4GB) when each DIMM is
installed with an 1GB memory module.

Important Notification about Power Issue

NForce chipset is very sensitive to ESD (Electrostatic Discharge), therefore
this issue mostly happens while the users intensively swap memory modules under
S5 (power-off) states, and the power code is plugged while installing modules. Due
to several pins are very sensitive to ESD, so this kind of memory-replacement actions
might cause system chipset unable to boot. Please follow the following solution to
avoid this situation.

Unplug the AC power cable (shown in figure 1) or unplug the JPWR1/ JPWR2/
JPWR3 power connectors (shown in figure 2 & 3) before the 1st installation or during
system upgrade procedure.
