The MSI special features are designed and developed by MSI R&D,
which are only available in MSI mainboards. The MS-6391 mainboard
is OPTIONALLY equipped with the following features:

PC Alert™ III

The PC AlertTM III 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:

*

monitor CPU & system temperatures

*

monitor fan speed(s)

*

monitor system voltage

*

monitor chassis intrusion

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 user disables the warning.

MSI Special Features

Note: Items shown on PC Alert III vary depending on your system’s
status.

D-LED™

The D-LED™ uses graphic signal display to
help users understand their system. Four LEDs em­bedded in the mainboard 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.

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.

The mainboard supports Intel® Pentium® 4 processor in FC-PGA2

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.

CPU Installation Procedures

1. Pull the lever sideways away

from the socket. Then, raise
the lever up to a 90-degree
angle.

2. Look for the dot/cut edge.

The dot/cut edge should
point towards 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 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
= 1.4GHz

1. Overheating

The issue of heat will seriously damage the CPU and
system, always make sure the cooling fan can work prop­erly to protect the CPU from overheating.

2. 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!

2-4

Installing the CPU Fan

As processor technology pushes to faster speeds and higher
performance, thermal managment 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.

NOTE: The figures in this section are for reference only. Actual
mainboard layout may be different from the one you purchased.

2. Position the heatsink onto

the retention mechanism.

5. Connect the fan power cable

from the mounted fan to the

on the mainboard.

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.

Synchronous DRAM is a type of dynamic RAM memory chip that has
been widely used starting in the latter part of the 1990s. SDRAMs are based on
standard dynamic RAM chips, but have sophisticated features that make them
considerably faster. First, SDRAM chips are fast enough to be synchronized
with the CPU's clock, which eliminates wait states. Second, the SDRAM chip is
divided into two cell blocks, and data is interleaved between the two so that
while a bit in one block is being accessed, the bit in the other is being prepared
for access. This allows SDRAM to burst the second and subsequent, contigu­ous characters at a rate of 10ns, compared to 60ns for the first character.

SDRAM provides 800 MBps or 1 GBps data transfer depending on
whether the bus is 100MHz or 133MHz.

Memory Bank Configuration

The mainboard supports a maximum memory size of 3GB. It

provides three 168-pin unbuffered SDRAM DIMM (Double In-Line
Memory Module) sockets and supports 64MB to 512MB technology.

Memory Installation Procedures

You can install memory modules in any combination as follows:

Installing DIMM Modules

1. The DIMM slot has 2 Notch Keys “VOLT and DRAM”, so the

DIMM memory module can only fit in one direction.

2. Insert the DIMM memory module vertically into the DIMM slot.

Then push it in.

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

The mainboard supports ATX power supply for the power system.

Before inserting the power supply connector, always make sure that all
components are installed properly to ensure that no damage will be
caused.

ATX 20-Pin Power Connector

This connector allows you to connect to an ATX power supply.

To connect to the ATX power supply, make sure the plugs of the power
supply is inserted in the proper orientation and the pins are aligned.
Then push down the power supply firmly into the connector. The power
connector supports instant power on function which means that system
will boot up immediately when the power supply connector is inserted
on the board.
