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.

Hardware Setup

Central Processing Unit: CPU

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

processors in the 462 pin package. The mainboard uses a CPU socket called
Socket A 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 cut edge. The 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.

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

KT3 Ultra2-C ATX Mainboard

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 Athlon™/Duron™/Athlon™ XP processor with a speed of 600MHz
and above requires a 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. If you want to get more information on the proper
cooling, you can visit AMD’s website for reference.

WARNING! Thermal Issue for CPU

2-5

Hardware Setup

CPU Clock Frequency Selection through BIOS

The hardware configuration for CPU clock frequency of the motherboard
is set to 100MHz by default. Therefore, to make a 133MHz CPU run at
133MHz when it is installed on the board, you have to adjust the CPU clock
frequency in the BIOS setup utility.

To set the clock frequency for the installed CPU, refer to Frequency/
Voltage Control in Chapter 3. BIOS Setup.

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
= 1.4 GHz

MSI Reminds You...

Replacing 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.

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.

KT3 Ultra2-C ATX Mainboard

The mainboard provides 2 slots for 184-pin DDR SDRAM DIMM
(Double In-Line Memory Module) modules and supports the memory size up
to 2GB. You can install PC2700/DDR333, PC2100/DDR266 or PC1600/
DDR200 modules on the DDR DIMM slots (DDR 1~2).

Memory

DDR DIMM Slots

(DDR 1~2)

Introduction to DDR SDRAM

DDR (Double Data Rate) SDRAM is similar to conventional SDRAM,
but doubles the rate by transferring data twice per cycle. It uses 2.5 volts as
opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM mod­ules rather than 168-pin DIMM modules used by SDR SDRAM. High memory
bandwidth makes DDR an ideal solution for high performance PC, worksta­tions and servers.

2-7

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 mod-

ule 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.

ATX 20-Pin Power Connector: JWR1

This connector allows you to connect to an ATX power supply. To
connect to the ATX power supply, make sure the plug 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.
