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
1-3-1 Installation of the CPU
Metal Lever
Fig. 1
Gently lift the metal
lever located on the
CPU socket to the
upright position.
Fig. 2
Remove the plastic
covering on the CPU
socket.
Fig. 3
Notice the small gold
colored triangle located
on the edge of the CPU
socket. Align the
indented corner of the
CPU with the triangle and gently insert the CPU into
position. (Grasping the CPU firmly between your
thumb and forefinger, carefully place it into the socket
in a straight and downwards motion. Avoid twisting or
bending motions that might cause damage to the CPU
during installation.)

Once the CPU is
properly inserted,
please replace the
load plate and
push the metal lever
back into its original
position.
1-3-2 Installation of the Heatsink
English
Male Push Pin
The top of Female Push Pin
Female Push Pin
Fig.1
Please apply an even layer of heatsink paste on
the surface of the installed CPU.
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. 5
Please check the back of motherboard after
installing. If the push pin is inserted as the picture,
the installation is complete.
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. 6
Finally, please attach the power connector of the
heatsink to the CPU fan header located on the
motherboard.
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.

1-4 Installation of Memory
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.
The motherboard supports DDR II memory modules, where by 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.
Notch
DDR II
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.
Fig.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.

Dual Channel Memory Configuration
The GA-8I945PLGE-RH supports the Dual Channel Technology. After operating the Dual Channel Technology, the bandwidth of Memory Bus will add
double.
The GA-8I945PLGE-RH includes 2 DIMM sockets.
If you want to operate the Dual Channel Technology, please note the following explanations
due to the limitation of Intel chipset specifications.
1. Dual Channel mode will not be enabled if only one DDR II memory module is installed.
2. To enable Dual Channel mode, please insert two DDR II memory modules (it is recommended to use memory modules of identical brand, size, chips, and speed) into DDRII1
and DDRII2 memory sockets.

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.
