follow the instructions below:
1. Please turn off the computer and unplug its power cord.
2. When handling the motherboard, avoid touching any metal leads or connectors.
3. It is best to wear an electrostatic discharge (ESD) cuff when handling electronic components
(CPU, RAM).
4. Prior to installing the electronic components, please have these items on top of an antistatic pad or
within a electrostatic shielding container.
5. Please verify that the power supply is switched off before unplugging the power supply connector
from the motherboard.

for warranty validation.
2. Prior to the installation of the motherboard or any hardware, please first carefully read the information
in the provided manual.
3. Before using the product, please verify that all cables and power connectors are connected.
4. To prevent damage to the motherboard, please do not allow screws to come in contact with the
motherboard circuit or its components.
5. Please make sure there are no leftover screws or metal components placed on the motherboard or
within the computer casing.
6. Please do not place the computer system on an uneven surface.
7. Turning on the computer power during the installation process can lead to damage to system
components as well as physical harm to the user.
8. If you are uncertain about any installation steps or have a problem related to the use of the product,
please consult a certified computer technician.
Instances of Non-Warranty
1. Damage due to natural disaster, accident or human cause.
2. Damage as a result of violating the conditions recommended in the user manual.

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.
English
2. Please take note of the one indented corner of the CPU. If you install the CPU in the wrong

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
English
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.

Dual Channel Memory Configuration
The GA-8I945PLGE-RH supports the Dual Channel Technology. After oper-
ating 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 recom-
mended to use memory modules of identical brand, size, chips, and speed) into DDRII1
and DDRII2 memory sockets.

1/2) ATX_12V/ATX (Power Connector)
English
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.
