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

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.

Open Lever

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.

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

Hardware Setup

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:

1. Locate the CPU and its retention

mechanism on the motherboard.

retention mechanism

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.

2. Position the heatsink onto the reten-

tion mechanism.

4. Press the two levers down to fasten

the fan. Each lever can be pressed
down in only ONE direction.

5. Connect the fan power cable from the mounted fan

to the 3-pin fan power connector on the board.

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

Overclocking

This motherboard is designed to support overclocking.

WARNING!

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.

Hardware Setup

Memory

The mainboard provides 3 slots for 184-pin, 2.5V DDR DIMM with 4
memory banks. You can install PC1600/PC2100 DDR SDRAM modules on the
DDR DIMM slots (DDR 1~3). To operate properly, at least one DIMM module
must be installed.

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. Two 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.

Note: DIMM 1~3 is separately 2-memory-bank capable. But as Intel

82845 chipset supports only 4 DDR memory banks, the total memory

banks installed cannot exceed the maximum quantity of 4. Improper

memory installation may possibly cause malfunction.

Chapter 2

DDR Module Combination

To enable normal operation, at least one DIMM module should be in­stalled on the motherboard. As Intel® 82845 chipset supports 4 DDR memory
banks at its maximum, the system memory installed can be up to 2GB.

All three slots can be single-sidedly or double-sidedly installed with 184­pin DDR DIMM modules. Please especially note that DDR 1 alone occupies
two memory banks; the rest two banks are shared by DDR 2 & DDR 3. You may
install memory modules in the following combination:

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.
