Hardware Installation

This section will guide you through the installation of the motherboard. The topics
covered in this section are:

q Preparing the motherboard

v Installing the CPU

v Installing the CPU fan

v Installing the memory

q Installing the motherboard

q Connecting cables and setting switches

Safety Instructions

To reduce the risk of re, electric shock, and injury, always follow basic safety precations.

Remember to remove power from your computer by disconnecting the AC main source
before removing or installing any equipment from/to the computer chassis.

9

Hardware Installation

Preparing the Motherboard

The motherboard shipped in the box does not contain a CPU and memory. You need

to purchase these to complete this installation.

Installing the CPU

Be very careful when handling the CPU. Make sure not to bend or break any pins on
the back. Hold the processor only by the edges and do not touch the bottom of the
processor.

Use the following procedure to install the CPU onto the motherboard.

1. Unhook the socket lever by pushing down and
away from the socket.

2. Lift the load plate. There is a protective socket
cover on the load plate to protect the socket
when there is no CPU installed.

3. Remove the protective socket cover from the
load plate.

4. Remove the processor from its protective cover,
making sure you hold it only by the edges.
It is a good idea to save the cover so that
whenever you remove the CPU, you have a
safe place to store it.

5. Align the notches in the processor with the
notches on the socket.

6. Lower the processor straight down into the
socket with out tilting or sliding it into the socket.

Note: Make sure the CPU is fully seated and
level in the socket.

7. Close the load plate over the CPU and press
down while you close and engage the socket
lever.

Installing the CPU Fan

There are many different fan types that can be used with this motherboard. Follow the
instruction that came with your fan assembly. Be sure that the fan orientation is correct
for your chassis type and your fan assembly.

Installing Memory DIMMs

Your new motherboard has two 1.8V 240-pin slots for DDR2 memory. These slots
support 256 MB / 512 MB /1GB / 2GB / 4GB DDR2 technologies. There must be at
least one memory bank populated to ensure normal operation. Use the following the
recommendations for installing memory. (See Figure1 for the location of the memory
slots.)

q One DIMM: You can install the DIMM into any slot,however,slot 1 is preferred.

q Two DIMMs: Install into slots 1 and 2,The idea is to run on dual channel mode.

DDRII-2

DDRII-1

11

Hardware Installation

Use the following procedure to install memory DIMMs into the slots on the mother­board. Note that there is only one gap near the center of the DIMM slot. This slot
matches the slot on the memory DIMM to ensure the component is installed prop­erly.

1. Unlock a DIMM slot by pressing the module clips outward.

2. Align the memory module to the DIMM slot, and insert the module vertically into
the DIMM slot. The plastic clips at both sides of the DIMM slot automatically lock
the DIMM into the connector.

Installing the Motherboard

The sequence of installing the motherboard into the chassis depends on the chassis

you are using and if you are replacing an existing motherboard or working with an

empty chassis. Determine if it would be easier to make all the connections prior to this
step or to secure the motherboard and then make all the connections. It is normally

easier to secure the motherboard rst.

Use the following procedure to install the I/O shield and secure the motherboard into
the chassis.

Note: Be sure that the CPU fan assembly has enough clearance for the
chassis covers to lock into place and for the expansion cards. Also
make sure the CPU Fan assembly is aligned with the vents on the
covers.

Installing the I/O Shield

The motherboard kit comes with an I/O shield that is used to block radio frequency

transmissions, protects internal components from dust and foreign objects, and
promotes correct airow within the chassis.

Before installing the motherboard, install the I/O shield from the inside of the chassis.

Press the I/O shield into place and make sure it ts securely. If the I/O shield does
not t into the chassis, you would need to obtain the proper size from the chassis

supplier.

Front panel header

The front panel header on this motherboard is one connector used

to connect the following four cables (see Table 2 for pin denitions):

q PWRLED
Attach the front panel power LED cable to these two pins of the connector. The
Power LED indicates the system’s status.

Note: Some chassis do not have all four cables. Be sure to match the name on
the connectors to the corresponding pins.

q PWR SW
Attach the power button cable from the case to these two pins. Pressing the
power button on the front panel turns the system on and off rather than using the
power supply button.
q HDD LED
Attach the hard disk drive indicator LED cable to these two pins. The HDD
indicator LED indicates the activity status of the hard disks.

q RST SW

Attach the Reset switch cable from the front panel of the case to these two pins.
The system restarts when the RESET switch is pressed.

S/PDIF

Short for Sony/Philips Digital Interface, a standard audio le transfer format. S/PDIF
allows the transfer of digital audio signals from one device to another without having

to be converted rst to an analog format. Maintaining the viability of a digital signal

prevents the quality of the signal from degrading when it is converted to analog.

Microphone

This page is designed to provide you better microphone / recording quality.

Below picture indicates both “Noise Suppression” & “Acoustic Echo
Cancellation” are both enabled.

Noise Suppression

If you feel that the background noise, especially the sound generated from the fan
inside PC, is too loud? Try “Noise Suppression”, which allows you to cut off and sup­press disturbing noise.

Beam Forming

Also known as “directional recording”, this option lets you do the following: Once beam
forming is enabled; only the sound from certain direction will be recorded. You will get
the best quality if you chose 90° position, which we recommend you to use, this ef­fectively means that you speak right into the microphone.

Note: A Stereo Microphone is required when using Beam Forming function.

Acoustic Echo Cancellation

This function prevents playback sound from being recorded by microphone together

with your sound. For example, you might have chance to use VOIP function through

Internet with your friends. The voice of your friend will come out from speakers (play­back). However, the voice of your friend might also be recorded into your microphone
then go back to your friend through Internet. In that case, your friend will hear his/her
own voice again. With AEC (Acoustic Echo Cancellation) enabled at your side, your

friend can enjoy the benet with less echo.
