1-1 Considerations Prior to Installation

Preparing Your Computer

The motherboard contains numerous delicate electronic circuits and components which can

become damaged as a result of electrostatic discharge (ESD). Thus, prior to installation, please

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 you the power supply is switched off before unplugging the power supply connector

from the motherboard.

Installation Notices

1. Prior to installation, please do not remove the stickers on the motherboard. These stickers are required

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.

1-4 Installation of Memory

Before installing the memory modules, please comply with the following conditions:

English

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 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

DDR

1. The DIMM slot has a notch, so the DIMM

memory module can only fit in one direction.

2. Insert the DIMM memory module vertically

into the DIMM slot. Then push it down.

3. Close the plastic clip at both edges of the DIMM

slots to lock the DIMM module.

Reverse the installation steps when you wish

to remove the DIMM module.

GA-8I915G-MF/GA-8I915GM Motherboard - 14 -

GA-8I915G-MF/GA-8I915GM supports the Dual Channel Technology. After operating the Dual

English

Channel Technology, the bandwidth of Memory Bus will double.

GA-8I915G-MF/GA-8I915GM includes 4 DIMM sockets, and each Channel has two DIMM sockets as

following:

Channel A : DDR 1, DDR 2

Channel B : DDR 3, DDR 4

If you want to operate the Dual Channel Technology, please note the following explanations due to

®

the limitation of Intel

chipset specifications.

1. Only one DDR memory module is installed: The Dual Channel Technology can't operate when

only one DDR memory module is installed.

2. Two DDR memory modules are installed (the same memory size and type): The Dual

Channel Technology will operate when two memory modules are inserted individually into

Channel A and B. If you install two memory modules in the same channel, the Dual

Channel Technology will not operate.

3. Three DDR memory modules are installed: Please note that The Dual Channel Technology

will not operate when three DDR memory modules are installed; part of them will not be

detected.

4. Four DDR memory modules are installed: If you install four memory modules at the same

time, the Dual Channel Technology will operate only when those modules have the same

memory size and type.

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

same color in order for Dual Channel Technology to work.

The following tables include all memory-installed combination types:

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.
