1-3 Installation of the CPU and Fan Heat Sink
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 fan heat sink.
4. Please make sure the fan heat sink 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.
1-3-1 Installation of the CPU
Check the processor pins to see that none are bent. Move the socket lever to the unlocked position as
shown in Fig. 1 (90o to the plane of the motherboard) prior to inserting the processor. The pin 1 location
is designated on the processor by a copper triangle that corresponds to a triangle marking on the socket
as shown in Fig. 2. Align the processor to the socket and gently lower it into place. Do not force the
processor into the socket.
Socket Lever
Please use extra care when installing the CPU. The CPU will not fit if positioned incorrectly.
Rather than applying force, please change the positioning of the CPU.
GA-K8N51GMF-9 Motherboard - 12 -
Fig.1
Position lever at a 90-degree angle.
Fig.2
Pin 1 location on the socket and processor.
Gently place the CPU into position making sure that the CPU pins fit
perfectly into their holes. Once the CPU is positioned into its socket,
place one finger down on the middle of the CPU and gently press the
metal lever back into its original position.
1-3-2 Installation of the Fan Heat Sink
Fig.1
Before installing the fan heat sink, please first add an even layer of heat
sink paste on the surface of the CPU. Install all the fan heat sink
components (Please refer to the heat sink manual for detailed installation
instructions).
Fig.2
Please connect the fan heat sink power connector to the CPU_FAN
connector located on the motherboard so that the heat sink can properly
function to prevent CPU overheating.
The heat sink may adhere to the CPU as a result of hardening of the heat sink 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 heat sink.

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

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 Memory Configuration
The GA-K8N51GMF-9 supports the Dual Channel Technology. When the Dual Channel Technology is
activated, the bandwidth of memory bus will be double the original one.
Due to CPU limitation, if you want to operate the Dual Channel Technology, please follow the guidelines
below for Dual Channel memory configuration.
1. Dual Channel mode will not be enabled if only one DDR memory module is installed.
2. To enable Dual Channel mode with 2 memory modules (it is recommended to use memory
modules of identical brand, size, chips, and speed), you must install them into DIMM sockets
of the same color.
3. To enable Dual Channel mode with 4 memory modules, it is recommended to use memory
modules of identical brand, size, chips, and speed.
The following is a Dual Channel Memory configuration table:
(DS: Double Side, SS: Single Side, --:Empty)
DDR 1 DDR 2 DDR 3 DDR 4
2 memory modules
4 memory modules
If two memory modules are to be used to achieve Dual Channel mode, we recommend
installing them in DDR1 and DDR2 DIMM sockets.
All of the memory configurations below will cause system unable to boot.

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.
