MSI Special Features
Features:
ØMSI Logo links to the MSI Web site
ØCPU Speed allows users to adjust the CPU speed through CPU
Multiplier and FSB
ØVoltage allows user to adjust the voltage of CPU/Memory/AGP
ØMSI Info provides information about the mainboard, BIOS and OS
ØCPU Info provides detailed information about the CPU
ØCPU Fan Speed shows the current running speed of CPU Fan
ØCPU Temp. shows the current CPU temperature
Fuzzy Logic™4
The Fuzzy Logic™ 4 utility is a user friendly tool that allows users to
view and adjust the current system status. To overclock the CPU FSB (Front
Side Bus) frequency under the Windows operating system, click FSB and use
the right and left arrow keys to select the desired FSB, and then click Apply to
apply the new setup value. To enable the system running at the specified FSB
every time when you click Turbo, click Save to save the desired FSB first. If
you want to know the maximal CPU overclocking value, click Auto to start
testing. The CPU FSB will automatically increase the testing value until the PC
reboots. After rebooting, click Turbo to apply the test result. Click Default to
restore the default values.
MSI Reminds You...
To adjust the options under CPU Speed and Voltage, use the right
and left arrow keys to select the desired value and then click Ap-
ply to run the setup value.

Live BIOS™/Live Driver™
The Live BIOS™/Live Driver™ is a tool used to detect and
update your BIOS/drivers online so that you don’t need to search
for the correct BIOS/driver version throughout the Web site. To
use the function, you need to install the “MSI Live Update 2”
application. After the installation, the “MSI Live Update 2” icon
(as shown on the right) will appear on the screen.
Double click the “MSI Live Update 2” icon, and the follow-
ing screen will appear:
Five buttons are placed on the leftmost pane of the screen. Click the desired
button to start the update process.

D-Bracket™ (Optional)
D-Bracket™ is a USB bracket integrating four Diagnostic LEDs, which
use graphic signal display to help users understand their system. The LEDs
provide up to 16 combinations of signals to debug the system. The 4 LEDs can
debug all problems that fail the system, such as VGA, RAM or other failures.
This special feature is very useful for the overclocking users. These users can
use the feature to detect if there are any problems or failures.

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

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

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.

Chapter 2

Central Processing Unit: CPU
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.
1. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree
angle.
2. Look for the gold arrow. The
gold arrow should point to-
wards the lever pivot. The
CPU will only fit in the correct
orientation.
3. Hold the CPU down firmly,
and then close the lever to
complete the installation.
CPUInstallationProcedures
Overheating will seriously damage the CPU and system,
always make sure the cooling fan can work properly to
protect the CPU from overheating.
