1-3 Installation of the CPU and Heatsink
Before installing the CPU, please comply with the following conditions:
English
1. Please make sure that the motherboard supports the CPU.
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:
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 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
English
GA-8I865GMK-775 / GA-8I865GMFK-775 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-8I865GMK-775 / GA-8I865GMFK-775 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. Dual channel memory cannot be used if one or three DDR memory modules are installed.
2. If two DDR 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 memory modules are installed on the same channel.
3. If four DDR 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 memory modules.
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)
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.
Please remove the sticker on the motherboard before plugging in while the ATX power supplier is 24
pins; Otherwise, please do not remove it.
