FCC-B Radio Frequency Interference Statement
This equipment has been tested and found to comply with the limits for a class
B digital device, pursuant to part 15 of the FCC rules. These limits are designed
to provide reasonable protection against harmful interference when the equip-
ment is operated in a commercial environment. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accor-
dance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to
cause harmful interference, in which case the user will be required to correct
the interference at his own expense.
Notice 1
The changes or modifications not expressly approved by the party respon-
sible 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
comply with the emission limits.

Hardware Setup
This chapter provides you with the information about hard-
ware setup procedures. While doing the installation, be careful
in holding the components and follow the installation
procedures. For some components, if you install in the wrong
orientation, the components will not work properly.
Use a grounded wrist strap before handling computer
components. Static electricity may damage the components.

Hardware Setup
Central Processing Unit: CPU
The mainboard supports AMD®Athlon™, Athlon™ XP and Duron™
processors in the 462 pin package. The mainboard uses a CPU socket called
Socket A 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.
As processor technology pushes to faster speeds and higher performance, ther-
mal management becomes increasingly crucial when building computer
systems. Maintaining the proper thermal environment is key to reliable
operation. As such, the processor must be maintained in the specified thermal
requirements.
AMD Athlon™/Duron™/Athlon™ XP processor with a speed of 600MHz
and above requires a LARGER heatsink and fan. You also need to add ther-
mal grease between the CPU and heatsink to improve heat dissipation. Then,
make sure that the CPU and heatsink are securely fastened and in good con-
tact with each other. These are needed to prevent damaging the processor and
ensuring reliable operation. If you want to get more information on the proper
cooling, you can visit AMD’s website for reference.
WARNING! Thermal Issue for CPU
CPU Core Speed Derivation Procedure
If CPU Clock = 100MHz
Core/Bus ratio = 14
then CPU core speed = Host Clock x Core/Bus ratio
= 100MHz x 14
= 1.4 GHz

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 to-
wards the lever pivot. The
CPU can only fit in the cor-
rect 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 pro-
cedures 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
tightly on top of the CPU to
make sure the CPU is prop-
erly and completely embed-
ded into the socket.

Hardware Setup
The following instructions will guide
you through the heat sink installation
procedures. Please consult your agent
for the proper CPU cooler set.
1. Position your CPU cooler set
onto the CPU.
2. Use one end of the clip to hook
the latch of the CPU sliding
plate.
3. Hook the other latch to fix the
cooling fan set. You may need a
screw drive to press down the
other side of the clip.
4. Connect the fan to the fan power
connector provided on your
mainboard.

MSI Reminds You...
Please apply some heat sink paste on top of CPU to dissipate
the heat more effectively.

MS-6596 M-ATX Mainboard
Setting CPU Clock Frequency through Jumper
The hardware configuration for CPU clock frequency of the motherboard
is set to 133MHz by default. Therefore, to make a 100/166MHz CPU run at
100/166MHz when it is installed on the board, you have to adjust the CPU
clock frequency through .
To set the clock frequency for the installed CPU, refer to Jumpers/FSB
Clock Jumper: SW1, SW2 in later section of this chapter.
MSI Reminds You...
Overheating
Overheating will seriously damage the CPU and system, al-
ways 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 sup-
ply 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 toler-
ate such abnormal setting, while doing overclocking. Any at-
tempt to operate beyond product specifications is not
recommended. We do not guarantee the damages or risks
caused by inadequate operation or beyond product
specifications.

Hardware Setup
The mainboard provides 2 slots for 184-pin DDR SDRAM DIMM
(Double In-Line Memory Module) modules and supports the memory size up
to 2GB. You can install PC2700/DDR333, PC2100/DDR266 or PC1600/
DDR200 modules on the DDR DIMM slots (DIMM 1~2).

DIMM Module Combination
Install at least one DIMM module on the slots. Memory modules can be
installed on the slots in any order. You can install either single- or double-
sided modules to meet your own needs.
Memory modules can be installed in any combination as follows:
Installing DDR Modules
1. The DDR DIMM has only one notch on the center of module. The mod-
ule 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 in-
serted 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. Be-
fore inserting the power supply connector, always make sure that all compo-
nents are installed properly to ensure that no damage will be caused.
ATX 20-Pin Power Connector: CONN1
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.
