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.

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.

Central Processing Unit: CPU

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.

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
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.

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

WARNING!

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.

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

5. Connect the fan power cable from the mounted fan to the 3-pin fan power connector

on the board.

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.

Memory

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. T wo types of
DDR are available at the time of writing: PC1600 & PC2100. PC1600 DDR SDRAM
running at 100MHz will produce about 1.6GB/s memory bandwidth. PC2100
running at 133MHz will produce 2.1GB/s memory bandwidth. High memory
bandwidth makes DDR an ideal solution for high performance PC, worksta­tions and servers.

The mainboard provides two 184-pin DDR DIMM slots and supports a

total memory size up to 2 GB.

DDR Module Combination

You can install either single sided or double sided DDR SDRAM mod-

ules into the DDR DIMM slots (DDR 1~2) in any combination as follows:

Socket Memory Module Total Memory

DIMM 1 64MB, 128MB,

64MB ~ 512MB

256MB, 512MB

DIMM 2 64MB, 128MB,

64MB ~ 512MB

256MB, 512MB

Maximum System Memory Supported 64MB ~ 2GB

DDR Module Installation Procedure

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.

Power Supply

A TX 20-Pin Power Supply

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.

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.

A TX 12V Power Connector: JPW1
