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.

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

English

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, 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.

Dual Channel DDR II

GA-8I945PMF supports the Dual Channel Technology. After operating the

Dual Channel Technology, the bandwidth of Memory Bus will double.

GA-8I945PMF includes 4 DIMM sockets, and each Channel has two DIMM sockets as following:

Channel A : DDR II 1, DDR II 2

Channel B : DDR II 3, DDR II 4

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 memory cannot be used if one or three DDR II memory modules are installed.

2. If two DDR II memory modules are installed (same storage capacity), one must be added to

the Channel A slot and the other in the Channel B slot in order to use dual channel memory.

Dual channel memory cannot function if both DDR II memory modules are installed on the

same channel.

3. If four DDR II memory modules are installed, please use memory of the same storage capacity

in order to use dual channel memory and for BIOS to detect all the DDR II memory modules.

We'll strongly recommend our user to slot two DDR II memory modules into the DIMMs with the same

color in order for Dual Channel Technology to work.

The following table is for Dual Channel Technology combination: (DS: Double Side, SS: Single Side)

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.
