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 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 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

Remove the plastic
covering on the CPU
socket.
Fig. 3
Notice the small gold
colored triangle lo-
cated on the edge of
the CPU socket.
Align the indented cor-
ner of the CPU with
Fig. 4
Once the CPU is
properly inserted,
please replace the
plastic covering and
push the metal lever
back into its original
position.
the triangle and gently insert the CPU into position.
(Grasping the CPU firmly between your thumb

1-3-2 Installation of the Heatsink
Fig.1
Please apply an even layer of heatsink paste on
the surface of the installed CPU.
The heatsink may adhere to the CPU as a result of hardening of the heatsink paste.To prevent
such an occurrence, it is suggested that either thermal tape rather than heat sink paste be used
for heat dissipation or using extreme care when removing the heatsink.
Fig. 6
Finally, please attach the power connector of the
heatsink to the CPU fan header located on the
motherboard.
Fig. 3
Place the heatsink atop the CPU and make sure
the push pins aim to the pin hole on the
motherboard.Pressing down the push pins
diagonally.
Fig. 2
(Turning the push pin along the direction of arrow
is to remove the heatsink, on the contrary, is to
install.)
Please note the direction of arrow sign on the male
push pin doesn't face inwards before installation.
(This instruction is only for Intel boxed fan)
Fig. 4
Please make sure the Male and Female push pin
are joined closely. (for detailed installation
instructions, please refer to the heatsink installation
section of the user manual)
Fig. 5
Please check the back of motherboard after
installing. If the push pin is inserted as the picture,
the installation is complete.

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 supports DDR memory modules, whereby BIOS will automatically detect memory
capacity and specifications. Memory modules are designed so that they can be inserted only in one
direction. The memory capacity used can differ with each slot.

Fig.1
The DIMM socket has a notch, so the DIMM memory module
can only fit in one direction. Insert the DIMM memory module
vertically into the DIMM socket. Then push it down.

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.

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 a AGP expansion 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.

1/2) ATX_12V/ATX (Power Connector)
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.
The ATX_12V power connector mainly supplies power to the CPU. If the ATX_12V power
connector is not connected, the system will not start.
Caution!
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 is used that does not provide the required power, the result can
lead to an unstable system or a system that is unable to start.
If you use a 24-pin ATX power supply, please remove the small cover on the power connector
on the motherboard before plugging in the power cord ; Otherwise, please do not remove it.
