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.

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:
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 send out a warning message. Click
Temperature to select the temperature modes of either Fahrenheit (℉) or Cel-
sius (℃). The PC Alert4 icon on the Status Area will show the current CPU
temperature.

MSI Reminds You...
The new feature COOLER XP will work only if your mainboard
supports AMD Athlon XP CPU.
Items shown on PC Alert 4 vary depending on your system’s status.
To better protect the CPU from overheating, a new feature, COOLER
XP, has been added to decrease the temperature of AMD Athlon XP CPU. To
do so, simply click COOLER XP and the screen will show the Cute skin (as
shown below) with information about the CPU and chipset. Right-click the
mouse to select the skin you want to switch to.

Setup
This chapter tells you how to install the CPU, memory
modules, and expansion cards, as well as how to setup the
jumpers on the mainboard. Also, it provides the instructions
on connecting the peripheral devices, such as the mouse,
keyboard, etc.
While doing the installation, be careful in holding the
components and follow the installation procedures.

Central Processing Unit: CPU
CPU Core Speed Derivation Procedure
CPU Clock multipled by Core/Bus ratio equals the CPU core speed.
For example:
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 AMD®Athlon™, Athlon™ XP and Duron™
processors in the 462 pin package. The mainboard uses a CPU socket called
Socket-462 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.
Thermal Issue for CPU
As processor technology pushes to faster speeds and higher
performance, thermal management becomes increasingly cru-
cial 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
recommends the use of high performance thermal interface material.
AMD Athlon™/Duron™ processor with a speed of 600MHz and above re-
quires LARGER heatsink and fan. You also need to add thermal grease be-
tween 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.
You can check AMD’s web site for more information.

CPU Installation Procedures for Socket 462
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 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.

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 power sup-
ply connector provided on your
mainboard.
