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.

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 memory support list.)

• 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 four 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 four DDR3 memory sockets are divided into two channels and each channel has two memory sockets as
following:

Channel 0: DDR3_2, DDR2_1
Channel 1: DDR3_4, DDR3_3

1/2) ATX_12V_2X4/ATX (2x4 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 com-

ponents 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.

• Use of a power supply providing a 2x4 12V power connector is recommended by the CPU
manufacturer when using an Intel Extreme Edition CPU (130W).

• 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.

• The power connectors are compatible with power supplies with 2x2 12V and 2x10 power
connectors. When using a power supply providing a 2x4 12V and a 2x12 power connector,
remove the protective covers from the 12V power connector and the main power connector on
the motherboard. Do not insert the power supply cables into pins under the protective covers
when using a power supply providing a 2x2 12V and a 2x10 power connector.

3/4) CPU_FAN/SYS_FAN (Fan Headers)

The motherboard has a 4-pin CPU fan header (CPU_FAN) and a 4-pin (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.
