1-3 Installation of the CPU and Heatsink
English
Before installing the CPU, please comply with the following conditions:
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.
HT functionality requirement content :
Enabling the functionality of Hyper-Threading Technology for your computer system requires all
of the following platform components:
- CPU: An Intel® Pentium 4 Processor with HT Technology
- Chipset: An Intel® Chipset that supports HT Technology
- BIOS: A BIOS that supports HT Technology and has it enabled
- OS: An operation system that has optimizations for HT Technology
1-3-1 Installation of the CPU
Metal Lever
Fig. 1
Gently lift the metal
lever located on the
CPU socket to the
upright position.
Fig. 2
Remove the plastic
covering on the CPU
socket.
Fig. 3
Notice the small gold
colored triangle located
on the edge of the CPU
socket. Align the
indented corner of the
CPU with the triangle and gently insert the CPU into
position. (Grasping the CPU firmly between your
thumb and forefinger, carefully place it into the socket
in a straight and downwards motion. Avoid twisting or
bending motions that might cause damage to the CPU
during installation.)
GA-8I865GM(F)K-775 Motherboard - 12 -
Fig. 4
Once the CPU is
properly inserted,
please replace the
plastic covering and
push the metal lever
back into its original
position.
1-3-2 Installation of the Heatsink
English
Male Push Pin
The top of Female Push Pin
Female Push Pin
Fig.1
Please apply an even layer of heatsink paste on
the surface of the installed CPU.
Fig. 3
Place the heatsink atop the CPU and make sure
the push pins aim to the pin hole on the
motherboard. Pressing down the push pins
diagonally.
Fig. 2
(Turning the push pin along the direction of arrow is
to remove the heatsink, on the contrary, is to install.)
Please note the direction of arrow sign on the male
push pin doesn't face inwards before installation. (This
instruction is only for Intel boxed fan)
Fig. 4
Please make sure the Male and Female push pin are
joined closely. (for detailed installation instructions,
please refer to the heatsink installation section of the
user manual)
Fig. 5
Please check the back of motherboard after
installing. If the push pin is inserted as the picture,
the installation is complete.
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.
Fig. 6
Finally, please attach the power connector of the
heatsink to the CPU fan header located on the
motherboard.

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
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
Fig.1
The DIMM socket has a notch, so the DIMM memory module can only
fit in one direction. Insert the DIMM memory module vertically into the
DIMM socket. Then push it down.
Fig.2
Close the plastic clip at both edges of the DIMM sockets to lock the
DIMM module.
Reverse the installation steps when you wish to remove the DIMM
module.

Dual Channel DDR
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)

when you try to install/uninstall the VGA
card. Please align the VGA card to the
onboard AGP slot and press firmly down on
the slot. Make sure your VGA card is locked
by the small white-drawable bar.

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.
