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:
zMSI Logo links to the MSI Web site
zCPU Speed allows users to adjust the CPU speed through CPU
Multiplier and FSB
zVoltage allows user to adjust the voltage of CPU/Memory/AGP
zMSI Info provides information about the mainboard, BIOS and OS
zCPU Info provides detailed information about the CPU
zCPU Fan Speed shows the current running speed of CPU Fan
zCPU 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™ 2 (Optional)
D-Bracket™ 2 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
detect all problems that fail the system, such as VGA, RAM or other failures.
This special feature is very useful for overclocking users. These users can use
the feature to detect if there are any problems or failures.
D-Bracket™ 2 supports both USB 1.1 & 2.0 spec.

Chapter 2. Hardware Setup
This chapter provides you with the information about hardware setup
procedures. While doing the installation, be careful in holding the compo-
nents 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
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.
3. HoldtheCPUdownfirmly,and
then close the lever to com-
plete 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.
WARNING!
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.
