PC Alert™ 4

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:

Ø monitor CPU & system temperatures
Ø monitor fan speeds
Ø monitor 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 send out a warning message. Click
Temperature to select the temperature modes of either Fahrenheit (oF) or Celsius
(oC). The PC Alert4 icon on the Status Area will show the current CPU
temperature.

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

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 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.

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 Installation Procedures for Socket 478

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 90­degree 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, always close the lever
with your fingers pressing
tightly on top of the CPU to
make sure the CPU is
properly and completely
embedded 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 reten­tion mechanism.

4. Press the two levers down to fasten

the fan. Each lever can be pressed
down in only ONE direction.

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 double­sided 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 in­serted in the socket.

3. The plastic clip at each side of the DIMM slot will automatically close.
