Hardware Setup
Central Processing Unit: CPU
The mainboard supports Intel® Pentium 4 / Celeron DTM (LGA775)
processor. The mainboard uses a CPU socket called LGA775. When you are
installing the CPU, make sure to install the heat sink/cooler to prevent
overheating. If you do not have the CPU, 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, Heatsink & Fan Installation
When you are installing the CPU, make sure the CPU has a heat
sink/ cooler fan attached on the top to prevent overheating. If you do
not have the heat sink/cooler fan, contact your dealer to purchase and install
them before turning on the computer. Meanwhile, do not forget to apply some
silicon heat transfer compound on CPU before installing the heat sink/cooler
fan for better heatsinking.
Follow the steps below to install the CPU & cooling fan correctly. Wrong
installation will cause the damage of your CPU & mainboard.
1.The CPU socket has a plastic
cap on it to protect the contact from damage. Always
cover it to protect the socket
pin until you are going to install the CPU.
3. The pins of socket reveal.
2.Remove the cap from lever hinge
side (as the arrow shows).
4.Open the load lever.

Hardware Setup
5.Lift the load lever up and open the
load plate.
6.After confirming the CPU direction for correction mating,
put down the CPU in the
socket housing frame. Be sure
to grape on the edge of the
substrate. Note that the alignment keys are matched.

7.Visually inspect if the CPU is
seated well into the socket. If not,
take out the CPU with purely vertical motion and reload it again.
8.Rotate the load plate onto the
package.

9.Engage the load while pressing down lightly onto the load
plate, and then secure the lever with the hook under retention tab.
11.Press the four hooks down
to fasten the fan. Then rotate the locking switch (refer
to the correct direction
marked on it) to lock the
hooks again.
10. Align the holes on the mainboard
with the heatsink first. Pull down
the fan/heatsink until its four clips
get wedged in the holes of the
mainboard.
12.Turn over the mainboard to confirm that the clip-ends are corrected inserted.

MSI Reminds You...
1. Confirm if your CPU heatsink/cooler is firmly installed before
turning on your system.
2. Check the information in PC Health Status of H/W Monitor
in BIOS (refer to p.3-20 for details) for the CPU temperature.
3. Make sure that the CPU socket pins are not turned up or
pressed down.

Hardware Setup
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 DDR 333/400 modules on the DDR DIMM slots (DIMM 1~4).
For the updated supporting memory modules, please visit http://www.msi.
com.tw/program/products/mainboard/mbd/pro_mbd_trp_list.php.
DDR DIMM Slots
(DIMM 1~4)
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.
2-7
MS-7133 M-ATX Mainboard
DIMM Module Combination
Install at least one DIMM module on the slots. You can install either single- or
double-sided modules in any order 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
DIMM 2 S/D 64MB~1GB
DIMM 3 S/D 64MB~1GB
DIMM 4 S/D 64MB~1GB
Maximum System Memory Supported 64MB~4GB
S: Single Side D: Double Side
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.

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 SSI power supply. To connect the SSI 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 or 24-pin
SSI power supply as you like. If you’d like to use the 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.

Connectors
The mainboard provides connectors to connect to FDD, IDE HDD, case,
LAN, USB Ports, IR module and CPU/System FAN.
Floppy Disk Drive Connector: FDD1
The mainboard provides a standard floppy disk drive connector that
supports 360K, 720K, 1.2M, 1.44M and 2.88M floppy disk types.
FDD1
Fan Power Connectors: CPUFAN1/SYSFAN1
The CPUFAN1(processor fan) and SYSFAN1 (system fan) support system cooling fan with +12V. It supports four/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.

IDE1 (Primary IDE Connector)
The first hard drive should always be connected to IDE1. IDE1 can connect a
Master and a Slave drive. You must configure second hard drive to Slave mode
by setting the jumper accordingly.

MSI Reminds You...
If you install two hard disks on cable, you must configure the
second drive to Slave mode by setting its jumper. Refer to the
hard disk documentation supplied by hard disk vendors for jumper
setting instructions.
Chassis Intrusion Switch Connector: JCASE1
This connector is connected to a 2-pin chassis switch. If the chassis is
opened, the switch will be short. The system will record this status and show
a warning message on the screen. To clear the warning, you must enter the
BIOS utility and clear the record.
