Core Center
The Core Center is a new utility you can find in the CD-ROM disk. The
utility is just like your PC doctor that can detect, view and adjust the PC
hardware and system status during real time operation. In the left side it shows
the current system status including the Vcore, 3.3V, +5V and 12V. In the right
side it shows the current PC hardware status such as the CPU & system
temperatures and all fans speeds.
When you click the red triangles in the left and right sides, two submenus will open for users to overclock, overspec or to adjust the thresholds of
system to send out the warning messages. If you click the Core Center button
in the top, a screen pops up for you to choose the “Auto mode” or “User

S-Bracket (Optional)
S-Bracket is a bracket which provides 2 SPDIF jacks for digital audio
transmission and 2 analog Line-Out connectors for additional 4-channel analog
audio output. With the S-Bracket, your system will be able to perform 6channel audio operation for wonderful surround sound effect, or connect to
Sony & Philips Digital Interface (SPDIF) speakers for audio transmission with
better quality.
The S-Bracket offers two types of SPDIF connectors: one for optical
fiber and the other for coaxial connection. Select the appropriate one to meet
your need. For more information on S-Bracket, refer to Appendix. Using 4- or

CPU Thermal Protection
Aimed to prevent the CPU from overheating, MSI has developed a CPU
Thermal Protection mechanism for Intel® CPU platform. This CPU Thermal
Protection mechanism works on a thermal signal sensor. If the mechanism
senses an abnormal temperature rise, it will automatically shut down the system
and the CPU temperature will then drop down and resume normal. With this
unique feature, users can better protect their CPU. Please note that this feature
is for Intel® Pentium CPU only.

CPU Core Speed Derivation Procedure
If CPU Clock = 100MHz
Core/Bus ratio = 16
then CPU core speed = Host Clock x Core/Bus ratio
= 100MHz x 16
= 1.6 GHz
The mainboard supports Intel® Pentium® 4 Northwood/Prescott processor
in the 478 pin package. The mainboard uses a CPU socket called PGA478 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.
MSI Reminds Y ou...
Overheating
Overheating will seriously damage the CPU and system, always
make sure the cooling fan can work properly to protect the CPU
from overheating.
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 478
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 90degree 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

Installing the CPU Fan
As processor technology pushes to faster speeds and higher performance,
thermal management becomes increasingly important. To dissipate heat, you
need to attach the CPU cooling fan and heatsink on top of the CPU. Follow
the instructions below to install the Heatsink/Fan:
2. Position the heatsink onto the reten-
tion mechanism.
1. Locate the CPU and its retention
mechanism on the motherboard.
3. Mount the fan on top of the heatsink.
Press down the fan until its four clips
get wedged in the holes of the retention mechanism.
4. Press the two levers down to fasten
the fan. Each lever can be pressed
down in only ONE direction.

Memory
DDR DIMM Slots
(DDR 1~4, from left to right)
Channel A: DIMM1 & DIMM2
Channel B: DIMM3 & DIMM4
The mainboard provides 4 slots for 184-pin, 2.5V DDR DIMM with 8
memory banks. Y ou can install DDR266/DDR333/DDR400 SDRAM modules on
the DDR DIMM slots (DIMM 1~4). To operate properly , at least one DIMM
module must be installed.
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. Please note that
the DDR SDRAM does not support ECC (error correcting code) and registered
DIMM.
DDR Population Rules
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 on p.
2-8).Users may install memory modules of different type and density on different-

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.

Please refer to the following table for detailed dual-channel DDR. Other

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.
A TX 20-Pin Power Connector: A TX1
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.
ATX 12V Power Connector: JPW1
This 12V power connector is used to provide power to the CPU.
