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

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.

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 II & 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.

Dual Channel DDR/DDR II

GA-8I915G Duo supports the Dual Channel Technology. After operating the Dual Channel Technology, the

bandwidth of Memory Bus will add double up to 6.4GB/s(DDR) ; 8.5GB(DDRII)

GA-8I915G Duo includes 4 DIMM sockets, and each Channel has two DIMM sockets as following:

Channel A : DDR 1 or Channel A : DDR II 1

Channel B : DDR 2 Channel B : DDR II 2

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

to the limitation of Intel chipset specifications.

1. One DDR/DDR II memory module is installed: The Dual Channel Technology can't operate

when only one DDR/DDR II memory module is installed.

2. Two DDR/DDR II 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.

We'll strongly recommend our user to slot two DDR/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)

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.
