Male Push Pin
Direction of the Arrow Sign on the Male Push Pin
The Top of Female Push Pin
Female Push Pin
Step 1: Apply an even and thin layer of thermal grease on the surface of the installed CPU.
Step 3: Place the cooler atop the CPU, aligning the four
push pins through the pin holes on the mother­board. Push down on the push pins diagonally.
Step 2: Before installing the cooler, note the direction of
the arrow sign on the male push pin. (Turn­ing the push pin along the direction of arrow is to remove the cooler, on the contrary, is to install.)
Step 4: You should hear a "click" when pushing down
each push pin. Check that the Male and Female push pins are joined closely. (Refer to your CPU cooler installation manual for instructions on installing the cooler.)
Step 5: After the installation, check the back of the moth-
erboard. If the push pin is inserted as the picture above shows, the installation is complete.
Step 6: Finally, attach the power connector of the CPU
cooler to the CPU fan header (CPU_FAN) on the motherboard.
Use extreme care when removing the CPU cooler because the thermal grease/tape between the CPU cooler and CPU may adhere to the CPU. Inadequately removing the CPU cooler may damage the CPU.
- 15 - Hardware Installation

1-4 Installing the Memory

Read the following guidelines before you begin to install the memory:
Make sure that the motherboard supports the memory. It is recommended that memory of the same capacity, brand, speed, and chips be used.
(Go to GIGABYTE's website for the latest supported memory speeds and memory modules.)
Always turn off the computer and unplug the power cord from the power outlet before installing the memory to prevent hardware damage.
Memory modules have a foolproof design. A memory module can be installed in only one direc­tion. If you are unable to insert the memory, switch the direction.
1-4-1 Dual Channel Memory Conguration
This motherboard provides two DDR3 memory sockets and supports Dual Channel Technology. After the memory is installed, the BIOS will automatically detect the specications and capacity of the memory. En­abling Dual Channel memory mode will double the original memory bandwidth. The two DDR3 memory sockets are divided into two channels and each channel has one memory socket as following:
Channel 0: DDR3_1 Channel 1: DDR3_2
DDR3_1
DDR3_2
Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one DDR3 memory module is installed.
2. When enabling Dual Channel mode with two memory modules, it is recommended that memory of the same capacity, brand, speed, and chips be used for optimum performance.
- 16 -Hardware Installation

1-4-2 Installing a Memory

Before installing a memory module, make sure to turn off the computer and unplug the power cord from the power outlet to prevent damage to the memory module. DDR3 and DDR2 DIMMs are not compatible to each other or DDR DIMMs. Be sure to install DDR3 DIMMs on this motherboard.

1/2) ATX_12V/ATX (2x2 12V Power Connector and 2x12 Main 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, rst make sure the power
supply is turned off and all devices are properly installed. The power connector possesses a foolproof design. Connect the power supply cable to the power connector in the correct orientation. The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not connected, the computer will not start.
To meet expansion requirements, it is recommended that a power supply that can withstand
high power consumption be used (500W or greater). If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system.

3/4) CPU_FAN/SYS_FAN (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN) and a 4-pin system fan header (SYS_FAN).
Most fan headers possess a foolproof insertion design. When connecting a fan cable, be sure to connect it in the correct orientation (the black connector wire is the ground wire). The motherboard supports CPU fan speed control, which requires the use of a CPU fan with fan speed control design. For optimum heat dissipation, it is recommended that a system fan be installed inside the chassis.

8) BAT (Battery)
The battery provides power to keep the values (such as BIOS congurations, date, and time information)
in the CMOS when the computer is turned off. Replace the battery when the battery voltage drops to a low level, or the CMOS values may not be accurate or may be lost.
You may clear the CMOS values by removing the battery:
1. Turn off your computer and unplug the power cord.
2. Gently remove the battery from the battery holder and wait for one minute. (Or use a metal object like a screwdriver to touch the positive and negative terminals of the battery holder, making them short for 5 seconds.)
3. Replace the battery.
4. Plug in the power cord and restart your computer.
Always turn off your computer and unplug the power cord before replacing the battery.
Replace the battery with an equivalent one. Danger of explosion if the battery is replaced with
an incorrect model.
Contact the place of purchase or local dealer if you are not able to replace the battery by your­self or uncertain about the battery model.
When installing the battery, note the orientation of the positive side (+) and the negative side (-)
of the battery (the positive side should face up).
Used batteries must be handled in accordance with local environmental regulations.
