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.

CPU Thermal Protection

Aimed to prevent the CPU from overheating, MSI has developed a CPU
Thermal Protection mechanism for AMD Athlon™ XP CPU platform. This CPU
Thermal Protection mechanism works on a thermal signal sensor. If the
mechanism senses an abnormal temperature rise, it will automatically shut down
the system and the CPU temperature will then drop down and resume normal.
With this unique feature, users can better protect their CPU. Please note that
this feature is for AMD Athlon™ XP CPU only.

CPU Core Speed Derivation Procedure

CPU Clock multipled by Core/Bus ratio equals the CPU core speed.

For example:
If CPU Clock = 100MHz

Core/Bus ratio = 14

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

= 100MHz x 14
= 1.4 GHz

The mainboard supports AMD® Athlon™, Athlon™ XP and Duron™

processors in the 462 pin package. The mainboard uses a CPU socket called
Socket-462 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.

Thermal Issue for CPU

As processor technology pushes to faster speeds and higher
performance, thermal management becomes increasingly crucial
when building computer systems. Maintaining the proper

thermal environment is key to reliable operation. As such, the
processor must be maintained in the specified thermal requirements. AMD
recommends the use of high performance thermal interface material.

AMD Athlon™/Duron™ processor with a speed of 600MHz and above
requires LARGER heatsink and fan. You also need to add thermal grease
between the CPU and heatsink to improve heat dissipation. Then, make sure
that the CPU and heatsink are securely fastened and in good contact with each
other. These are needed to prevent damaging the processor and ensuring
reliable operation.

You can check AMD’s web site for more information.

WARNING!

MS-6764 ATX Mainboard

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.

Memory

The mainboard provides two 184-pin unbuffered PC2700/PC2100/
PC1600 DDR SDRAM or two 168-pin unbuffered PC100/133 SDRAM and
supports the memory size up to 2GB. To operate properly, at least one DIMM
module must be installed.

MSI Reminds You...

Make sure that you install only one type of memory modules
(either SDR or DDR) at one time. DO NOT install both types at

the same time. For security reason, the system will automati­cally power off if you simultaneously install SDR & DDR
memory modules onboard.

Hardware Setup

DIMM Module Combination

Install at least one DIMM module on the slots. Memory modules can be
installed on the slots in any order. You can install either single- or double­sided modules to meet your own needs.

Memory modules can be installed in any combination as follows:

Installing DDR Modules

1. The DDR DIMM has only one notch on the center of module. The module

will only fit in the right orientation.

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

push it in until the golden finger on the memory module is deeply inserted
in the socket.

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