MSI Special Features
PC Alert™ III
The PC AlertTM III is a utility you can find in the CD-ROM disk. The
utility is just like your PC doctor that can de-
tect the following PC hardware status during
real time operation:
* monitor CPU & system temperatures
* monitor fan speed(s)
* monitor system voltage
* monitor chassis intrusion
If one of the items above is abnormal,
the program main screen will be immediately
shown on the screen, with the abnormal item
highlighted in red. This will continue to be
shown until users disable the warning.
Note: Items shown on PC Alert III vary depending on your system’s
status.

Hardware Setup
This chapter provides you with the information about hardware 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.

1. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree
angle.
2. Look for the dot/cut edge. The
dot/cut edge should point to-
wards the lever pivot. The
CPU will only fit in the correct
orientation.
3. 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 finger pressing
tightly on top of the CPU to
make sure the CPU is properly
& completely embedded into
the socket.

The mainboard supports Intel®Pentium®4 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
sinkandacoolingfanattachedonthetoptopreventoverheating. Ifyoudonot
find the heat sink and cooling fan, contact your dealer to purchase and install
them before turning on the computer.
Overheating will seriously damage the CPU and system,
always make sure the cooling fan can work properly to
protect the CPU from overheating.
WARNING!

InstallingtheCPU Fan
As processor technology pushes to faster speeds and higher
performance, thermal management becomes increasingly important. To dissi-
pate 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 reten-
tion mechanism.
4. Press the two levers down to fasten
the fan. Each lever can be pressed
down in only ONE direction.

CPU Core Speed Derivation Procedure
If CPUClock = 100MHz
Core/Bus ratio = 14
then CPU core speed = Host Clock x Core/Bus ratio
= 100MHzx14
= 1.4GHz
5. Connect the fan power cable from the mounted fan to the 3-pin fan power connector
on the board.

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.
