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

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.

The heatsink may adhere to the CPU as a result of hardening of the heatsink paste.To prevent

such an occurrence, it is suggested that either thermal tape rather than heat sink paste be used for

heat dissipation or using extreme care when removing the heatsink.

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

Fig.1

The DIMM socket has a notch, so the DIMM memory module

can only fit in one direction. Insert the DIM M memory module

vertically into the DIMM socket. Then push it down.

lock the DIMM module.

Reverse the installation steps when you wish to remove the

Dual Channel DDR

GA-8IP775 series supports the Dual Channel Technology. After operating the Dual Channel Technology, the

bandwidth of Memory Bus will add double up to 6.4GB/s.

GA-8IP775 series 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 lim itation of Intel chipset specifications.

1. One/three 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. 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 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.

Please remove the sticker on the motherboard before plugging in while the ATX power supplier is 24

pins; Otherwise, please do not remove it.
