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 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

1-3-2 Installation of the CPU Cooler
Male Push Pin
Female Push Pin
The top of Female Push Pin
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.
Fig. 6
Finally, please attach the power connector of the
CPU cooler to the CPU fan header located on the
motherboard.
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. 4
Please make sure the Male and Female push pin
are joined closely. (for detailed installation
instructions, please refer to the CPU cooler instal-
lation 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.
Fig.1
Please apply an even layer of CPU cooler paste
on the surface of the installed CPU.
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)

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 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 mod-
ule 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.

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 install 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.
For example: Installing a PCI Express x16 VGA card:
When removing the graphics card, gently
push back on the black lever on the slot
and then lift the card straight out from the
slot.
When installing the graphics card, push
down on the top edge of the card until it is
fully inserted into the PCI Express x16
slot. Make sure the card is securely
seated in the slot and does not rock.
Dual Channel Memory Configuration
The GA-945GZM-S2 supports the Dual Channel Technology. After operating
the Dual Channel Technology, the bandwidth of Memory Bus will double.
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 memory module is installed.
2. To enable Dual Channel mode with two memory modules (it is recommended to use memory
modules of identical brand, size, chips, and speed), you must install them into DIMM sockets
of the same color.

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.

3/4) CPU_FAN / SYS_FAN (Cooler Fan Power Connector)
The cooler fan power connector supplies a +12V power voltage via a 3-pin/4-pin (only for
CPU_FAN) power connector and possesses a foolproof connection design.
Most coolers are designed with color-coded power connector wires. A red power connector
wire indicates a positive connection and requires a +12V power voltage. The black connector
wire is the ground wire (GND).
Remember to connect the CPU/system fan cable to the CPU_FAN/SYS_FAN connector to prevent
CPU damage or system hanging caused by overheating.
5) IDE (IDE Connector)
An IDE device connects to the computer via an IDE connector. One IDE connector can connect to
one IDE cable, and the single IDE cable can then connect to two IDE devices (hard drive or optical
drive). If you wish to connect two IDE devices, please set the jumper on one IDE device as Master
and the other as Slave (for information on settings, please refer to the instructions located on the IDE
device). Before attaching the IDE cable, please take note of the foolproof groove in the IDE connector.
