The PC AlertTM 4 is a utility you can find in the CD-ROM disk. The utility
is just like your PC doctor that can detect the following PC hardware status
during real time operation:
Ømonitor CPU & system temperatures
Ømonitor fan speeds
Ømonitor system voltages
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 the condition returns to the normal status.
Users can use the Adjusting Keys to change the minimum and maximum
threshold of each item for the system to
sendoutawarningmessage. ClickTempera-
ture to select the temperature modes of ei-
ther Fahrenheit (oF) or Celsius (oC). The PC
Alert™ 4 icon on the Status Area will show the current CPU temperature.

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.

CPU Core Speed Derivation Procedure
If CPU Clock = 100MHz
Core/Bus ratio = 24
then CPU core speed = Host Clock x Core/Bus ratio
= 100MHz x 24
= 2.4 GHz
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.
The mainboard supports Intel®Pentium®4 processors 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.

MS-6787 M-ATX Mainboard
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 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.

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 reten-
tion mechanism.
4. Press the two levers down to fasten
the fan. Each lever can be pressed
down in only ONE direction.
