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 equip­ment is operated in a commercial environment. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accor­dance 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 respon­sible 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.

MSI Special Features

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:

Ø monitor CPU & system temperatures
Ø monitor fan speeds
Ø monitor 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 Cel­sius (℃). 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.

CPU Core Speed Derivation Procedure

If CPU Clock = 100MHz

Core/Bus ratio = 17

then CPU core speed = Host Clock x Core/Bus ratio

= 100MHz x 17
= 1.7 GHz

The mainboard supports Intel® Pentium® 4 Northwood 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.

MSI Reminds You...

Overheating

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

Replacing the CPU

While replacing the CPU, always turn off the ATX power sup­ply or unplug the power supply’s power cord from grounded
outlet first to ensure the safety of CPU.

650GLMS Micro ATX Mainboard

CPU Installation Procedures for Socket 478

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 90­degree angle.

3. Look for the gold arrow. The
gold arrow should point to­wards 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.

Installing the CPU Fan

As processor technology pushes to faster speeds and higher performance,
thermal management 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:

2. Position the heatsink onto the reten-

tion 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.

Hardware Setup

The mainboard provides 2 sockets for 168-pin unbuffered SDRAM

DIMM (Double In-Line Memory Module) modules and supports a maximum
memory size of 2GB.

(DIMM 1&2, from right to left)

Introduction to SDRAM

Synchronous DRAM (SDRAM) 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.

2-8

650GLMS Micro ATX Mainboard

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 each side of the DIMM slot will automatically close.

DIMM Module Combination

At least one DIMM module should be installed on the motherboard.
Memory modules can be installed on the slots in any order. The single-/
double-sided memory modules that each DIMM slot supports are listed as
below:
