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 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.
1-3-1 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 Figure 1.(90oto the plane of the motherboard) prior to inserting the processor. The pin 1 location is
designated on the processor by a copper triangle that matches up to a triangle on the socket as shown in
Figure 2.Align the processor to the socket and gently lower it into place. Do not force the processor into the
socket.
Fig.1
Position lever at a 90 degree angle.
Socket lever
Fig.2
A gold-colored triangle is marked one edge of the CPU. Please align this
edge with the socket edge closest to the CPU lever. Gently place the CPU
into position making sure that the CPU pins fit perfectly into their holes.
Once the CPU is positioned into it socket, place one finger down on the
middle of the CPU and gently press the metal lever back into its original
position.
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.

1-3-2 Installation of the Fan Heat Sink
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.
Fig.1
Before installing the heat sink, please first add an even layer of heat sink
pasteon the surface ofthe CPU. Install allthe heat sink components(Please
refer to the heat sink manual for detailed installation instructions).
Fig.2
Please connect the 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.

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. Amemory module can be installed in
only one direction. If you are unable to insert the module, please switch the direction.
1-4 Installation of Memory
The motherboard supports DDR memory modules, whereby BIOS will automatically detect memory
capacityand specifications. Memory modules aredesigned so that theycan 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 Memory Configuration
The GA-K8NF9-SI 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)

If two memory modules are to be used to achieve Dual Channel mode, we recommend
installing them in DDR1 and DDR2 DIMM sockets.

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.
TheATX_12V power connector mainly supplies power to the CPU. If theATX_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.

The cooler fan power connector supplies a +12V power voltage via a 3-pin power connector and
possesses a foolproof connection design.
Most coolers are designed with color-coded power connector wires. A red power connector wire
indicates a positive connection and requires a +12V power voltage. The black connector wire is the
ground wire (GND).
Please remember to connect the power to the cooler to prevent system overheating and failure.
