MSI Special Features
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.
Features:
lMSI Logo links to the MSI Web site
lCPU Speed allows users to adjust the CPU speed through CPU
Multiplier and FSB
lVoltage allows user to adjust the voltage of CPU/Memory/AGP
lMSI Info provides information about the mainboard, BIOS and OS
lCPU Info provides detailed information about the CPU
lCPU Fan Speed shows the current running speed of CPU Fan
lCPU Temp. shows the current CPU temperature
Note: To adjust the options under CPU Speed and Voltage, use the
right and left arrow keys to select the desired value and then click
Apply to run the setup value.

D-Bracket (optional)
D-Bracket is an 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.
D-Bracket Description

Chapter 2. 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.

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
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.
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.
CPU Installation Procedures
Overheating will seriously damage the CPU and system,
always make sure the cooling fan can work properly to
protect the CPU from overheating.

Installing the CPU 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 re-
tention 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.

CPU Core Speed Derivation Procedure
If CPU Clock = 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.
WARNING!
