							2-3 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, thermal
management becomes increasingly crucial when building computer systems.  Main-
taining 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 thermal grease between
the CPU and heatsink to improve heat dissipation.  Then, make sure that the CPU and
heatsink are securely fastened and in good contact 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.

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-de-
gree 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, al-
ways close the lever with your
fingers pressing tightly on top of
the CPU to make sure the CPU is
properly and completely embed-
ded into the socket.

Installing AMD Athlon CPU (Socket 462) Cooler Set
Apply some heat
sink paste
MSI Reminds You...
Please apply some heat sink paste on top of your CPU to dissipate
the heat more effectively. 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 power supply
connector provided on your
mainboard.

CPU Clock Frequency Selection through BIOS
The hardware configuration for CPU clock frequency of the motherboard is set to
100MHz by default.  Therefore, to make a 133MHz CPU run at 133MHz when it is
installed on the board, you have to adjust the CPU clock frequency in the BIOS setup
utility.
To set the clock frequency for the installed CPU, refer to Frequency/Voltage Control
in Chapter 3. BIOS Setup.
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 abnor-
mal setting, while doing overclocking.  Any attempt to operate be-
yond product specifications is not recommended.  We do not guar-
antee the damages or risks caused by inadequate operation
or beyond product specifications.

Memory
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 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:
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.
