1-3 Installation of the CPU and Heatsink

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 pin one marks on the processor and socket. 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 heatsink.

4. Please make sure the heatsink 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 not

recommended 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 Intel

®

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 Technology

1-3-1 Installation of the CPU

2. Raise the processor socket

handle all the way up to a fully

raised position (around 90

degrees) till you hear a "click."

Fully raise the pro-

cessor socket handle.

1. Raise the processor socket handle to

approved cooling fan.

00

0 We recommend you to apply the thermal tape to provide better heat conduc

tion between your CPU and heatsink. (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 in

stead of thermal paste, or remove the cooling fan with extreme caution.)

00

0 Make sure the CPU fan power cable is plugged in to the CPU fan connector,

this completes the installation.

00

0 Please refer to CPU heat sink user’s manual for more detail installation

procedure.

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.

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.

3. Locate the Pin One Indicator on the

processor.

Before installing the memory modules, please comply with the following conditions:

1. Please make sure that the memory used is supported by the motherboard. It is recommended that

memory of similar capacity, specifications and brand be used.

2. Before installing or removing memory modules, please make sure that the computer

power is switched off to prevent hardware damage.

3. Memory modules have a foolproof insertion design. A memory module can be

installed in only one direction. If you are unable to insert the module, please switch the

direction.

1-4 Installation of Memory

The motherboard has 2 dual inline memory module (DIMM) sockets. The BIOS will automatically

detects memory type and size. To install the memory module, just push it vertically into the DIMM

socket. The DIMM module can only fit in one direction due to the notch. Memory size can vary between

sockets.

3. Close the plastic clip at both edges of the DIMM

slots to lock the DIMM module.

Reverse the installation steps when you wish

to remove the DIMM module.

1. The DIMM slot has a notch, so the DIMM

memory module can only fit in one direction.

2. Insert the DIMM memory module vertically

into the DIMM slot. Then push it down.

1-5 Installation of Expansion Cards

You can install your expansion card by following the steps outlined below:

1. Read the related expansion card's instruction document before installing the expansion card into

the computer.

2. Remove your 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 metal contacts on the card are indeed seated in the slot.

5. Replace the screw to secure the slot bracket of the expansion card.

6. Replace your computer's chassis cover.

7. Power on the computer, if necessary, setup BIOS utility of expansion card from BIOS.

8. Install related driver from the operating system.

Installing an AGP expansion card:

AGP Card

Please carefully pull out the small white-drawable

bar at the end of the AGP slot when you try to

install/uninstall the VGA card. Please align the VGA

card 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.

4) ATX (ATX Power)

With the use of the power connector, the power supply can supply enough stable power to all

the components on the motherboard. Before connecting the power connector, please make sure

that all components and devices are properly installed. Align the power connector with its

proper location on the motherboard and connect tightly.

Please use a power supply that is able to handle the system voltage requirements. It is

recommended that a power supply that can withstand high power consumption be used (300W

or greater). If a power supply that does not provide the required power is used, the result can

lead to an unstable system or a system that is unable to start.
