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 equip-
ment is operated in a commercial environment. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accor-
dance 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.

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.

Chapter 2
2-2
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.
1. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree
angle.
2. Look for the gold arrow. The
gold arrow should point to-
wards 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.
CPU Installation Procedures
Overheating will seriously damage the CPU and system,
always make sure the cooling fan can work properly to
protect the CPU from overheating.

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 re-
tention 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
= 100MHzx14
= 1.4GHz
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.
WARNING!
5. Connect the fan power cable from the mounted fan to the 3-pin fan power
connector on the board.

Hardware Setup

The mainboard provides 2 slots for 184-pin, 2.5V unbuffered DDR DIMM
with 4 memory banks. You can install PC1600/PC2100 DDR/PC2700 SDRAM
modules on the DDR DIMM slots (DDR 1~2). To operate properly, at least one
DIMM module must be installed.
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 op-
posed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM modules
rather than 168-pin DIMM modules used by SDR SDRAM. Three types of
DDR SDRAM are available at the time of writing: PC1600, PC2100 and PC2700.
The following table shows the clock and peak bandwidth of each type of
DDR SDRAM module:
PC2700 PC2100 PC1600
(DDR333) (DDR266) (DDR200)
Clock 166MHz 133MHz 100MHz

DDR Module Combination
You can install either single-sided or double-sided 184-pin DDR DIMM
modules into DDR DIMM slots to meet your needs. Different from the SDR
DIMM, the DDR DIMM has only one notch on the center of module. The
number of pins on either side of the breaks are different. The module will only
fit in the right orientation.
You can install memory modules 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.
3. The plastic clip at each side of the DIMM slot will automatically close.

Power Supply
ATX 20-Pin Power Connector: CONN1
This connector allows you to connect to an ATX power supply. To con-
nect 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. Be-
fore inserting the power supply connector, always make sure that all compo-
nents are installed properly to ensure that no damage will be caused.
ATX 12V Power Connector: JPW1
This 12V power connector is used to provide power to the CPU.
