Chapter 3 Hardware Installation
Considerations Prior to Installation
Preparing Your Computer:
The motherboard contains numerous delicate electronic circuits and components which can become damaged as a
result of electrostatic discharge (ESD). Thus, prior to installation, please followthe instructions below:
1. Please turn off the computer and unplug its power cord.
2.When handling the motherboard, avoid touching anymetalleads or connectors.
3. It is best to wear an electrostatic discharge (ESD) cuff when handling electronic components(CPU, RAM).
4. Prior to installing the electronic components, please have these items on top of an antistatic pad or within a
electrostatic shielding container.
5. Please verifythat you the power supply is switched off before unplugging the power supply connector from the
motherboard.
Installation Notices:
1. Prior to installation, please do not remove the stickers on the motherboard. These stickers are required for
warrantyvalidation.
2. Prior to the installation of the motherboard or anyhardware, please first carefully read the information in the
provided manual.
3. Before using the product, please verifythat all cables and power connectors are connected.
4. To prevent damage to the motherboard, please do not allowscrews to come in contact with the motherboard
circuit or its components.
5. Please make sure there are no leftover screws or metalcomponents placed on the motherboard or within the
computer casing.
6. Please do not place the computer system on an uneven surface
7. Turning on the computer power during the installation process can lead to damage to systemcomponents as well
as physicalharm to the user.
8. If you are uncertain about anyinstallation steps or have a problem related to the use of the product, please
consult a certified computer technician.

Installation of the CPU and Heat-sink
Before installing the CPU, please comply with the following conditions:
1. Please make sure that the motherboard supports the CPU.
2. Please take note of the one indented corner of the CPU. If you install the CPU in the wrong direction, the CPU
will not insert properly. If this occurs, please change the insert direction of the CPU.
3. Please add an even layer of heat sink paste between the CPU and heat-sink.
4. Please make sure the heat-sink is installed on the CPU prior to system use, otherwise overheating and permanent
damage of the CPU may occur.
5. Please set the CPU host frequency in accordance with the processor specifications. It is no true commended
that the system bus frequency be set beyond hardware specifications since it does not meet the required
standards for the peripherals. If you wish to set the frequency beyond the proper specifications, please do so
according to your hardware specifications including the CPU, graphics card, memory, hard drive, etc.
HT functionality requirement content :
Enabling the functionality of Hyper-Threading Technology for your computer system requires all of the following
platform components:
- CPU: An Intel® Pentium 4 Processor with HT Technology
- Chipset: An SiS® Chipset that supports HT Technology
- BIOS: A BIOS that supports HT Technology and has it enabled
- OS: An operation system that has optimizations for HT Technology1-3-1Installation of the CPU
Installation of the CPU
1.Raise the processor socket
handle to 65 degrees. You
maybe feel a kind of tight
2.Raise the processor socket
handle all the way up to a fully
raised position (around
90degrees) till you hear a
"click."

15
Installation of the heat-sink
Note:
1. Please use Intel® approved cooling fan.
2. We recommend you to apply the thermal tape to provide better heat conduction between your
CPU and heat-sink. (The CPU cooling fan might stick to the CPU due to the hardening of the
thermal paste. During this condition if you try to remove the cooling fan, you might pull the
processor out of the CPU socket alone with the cooling fan, and might damage the processor. To
avoid this from happening, we suggest you to either use thermal tape instead of thermal paste, or
remove the cooling fan with extreme caution.)
3. Make sure the CPU fan power cable is plugged in to the CPU fan connector this completes the
installation.
4. Please refer to CPU heat sink user’s manual for more detail installation procedure
3. Locate the Pin One
Indicator on the
processor.
4. Locate Pin One in
the socket and look for
a (golden) cut edge on
the CPU upper corner.
Then insert the CPU
into the socket and
close the socket handle
1. Push down the
cooler clip to secure
to the retention
mechanism hooks for
all four corners.
2. Plug the cooler
power cable into the
CPU fan connector on
the motherboard.

16
Installation ofMemory
Before installing the memorymodules, please comply with the following conditions:
1. Please make sure that the memoryused is supported bythe mother-board. It is recommended that memoryof
similar capacity, specifications and brand be used.
2. Before installing or removing memorymodules, please make sure that the computer power is switched off to
prevent hardware damage.
3. Memorymodules have a foolproof insertion design. A memorymodule can be installed in only one direction.
4. If you are unable to insert the module, please switch thedirection.1-4Installation of Memory
The motherboard has 2dualinline memorymodule (DIMM) sockets. The BI OSwill automatically detect memory
type and size. To install the memorymodule, just push it vertically into the DIMM socket. The DIMM module can
only fit in one direction due to the notch. Memorysize can varybetween sockets.
1. The DIMM socket has a notch, so the
DIMM memorymodule can only fit in one
direction. Insert the DIMM memory
modulevertically into the DIMM socket.
Then push it down.

Installation of Expansion Cards
You can install your expansion card byfollowing the steps outlined below:
1. Read the related expansion card's instruction document before installing the expansion card into the computer.
2. Removeyour computer's chassis cover, screws and slot bracket from the computer.
3. Press the expansion card firmly into expansion slot in motherboard.
4. Be sure the metalcontacts on the card are indeed seated in the slot.
5. Replace the screwto secure the slot bracket of the expansion card.
6. Replace your computer's chassis cover.
7. Power on the computer, if necessary, setup BIOSutilityof expansion card from BIOS.
8. Install related driver from the operating system.
Installing a AGP expansion card:
AGP Card
2.Close the plastic clip at both edges of
the DIMM sockets to lock the DIMM
module. Reverse the installation steps
when you wish to remove the DIMM
module.
Please carefully pull out the small
white-drawable bar at the end of the
AGP slot when you tryto
install/uninstall the VGA card. Please
align the VGAcard to the onboard AGP
slot and press firmly down on the slot.
Make sure your VGA card is locked by
the small white-drawable bar.
