1-3 Installation of the CPU and CPU Cooler
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 CPU cooler.
4. Please make sure the CPU cooler 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 Cooler
English
Male Push Pin
The top of Female Push Pin
Female Push Pin
Fig.1
Please apply an even layer of CPU cooler paste
on the surface of the installed CPU.
Fig. 3
Place the CPU cooler 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 CPU cooler, 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 CPU cooler installation section of the user manual)
Fig. 6
Finally, please attach the power connector of the
CPU cooler to the CPU fan header located on the
motherboard.
The CPU cooler may adhere to the CPU as a result of hardening of the heat paste. To prevent
such an occurrence, it is suggested that either thermal tape rather than heat paste be used for
heat dissipation or using extreme care when removing the CPU cooler.

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 DDRII 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.
Notch
DDRII
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.
GA-945PL-S3 Motherboard - 14 -
Dual Channel Memory Configuration
GA-945PL-S3 supports the Dual Channel Technology. After operating the
Dual Channel Technology, the bandwidth of Memory Bus will add double.
GA-945PL-S3 includes 4 DIMM sockets, and each Channel has two DIMM
sockets as following:
Channel 0 : DDRII1, DDRII2
Channel 1 : DDRII3, DDRII4
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/three DDRII memory module is
installed.
2. To enable Dual Channel mode with two or four memory modules (it is recommended to
use memory modules of identical brand, size, chips, and speed), install the memory
according to the dual channel memory configuration table below (Figure 1).

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.
