1.Please note that users cannot install OS, either WinME or Win98, in
their SATA hard drive. Under these two OSs, SATA can only be used
as a normal storage device.

2.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 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.

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.

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 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.

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.Detach the shield of the backplate’s
paster.

2.Turn over the mainboard, and install
the backplate to the proper position.

3.Turn over the mainboard again, and
place the mainboard on the flat
surface.

Locate the two screw holes of the
mainboard.

4.Align the retention mechanism and
the backplate.

Fix the retention mechanism and the
backplate with two screws.

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.

6.Locate the Fix Lever, Saftey Hook

and the Fixed Bolt.

7.Fastened down the lever.

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

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/
333/400/433/466/500/533 modules on the DDR DIMM slots (DDR 1~4).
For the updated supporting memory modules, please visit http://www.msi.com.tw/

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.

-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 unkonwn 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.

-This mainboard DO NOT support the memory module installed
with more than 18 pieces of IC (integrated circuit).

2. 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.

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.

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 chipset system unable to boot. Please follow the following solution to
avoid this situation.

Unplug the AC power cable (shown in figure 1) or unplug the ATX1 & JPW1 power
connectors (shown in figure 2 & figure 3) before the 1st installation or during sys­tem upgrade procedure.

Fan Power Connectors: CPUFAN1 / SFAN1 / SFAN2 / NBFAN1

The CPUFAN1 (processor fan), SFAN1 (system fan 1), SFAN2 (system fan 2) and
NBFAN1 (NorthBridge Chipset fan) 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.CPUFAN1 supports fan control. You can install Core Center util­ity that will automatically control the CPU fan speed according to
the actual CPU temperature.

3. Please refer to the recommended CPU fans at AMD® official
website.
