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 Configuration

This motherboard provides two DDR3 memory sockets and supports Dual Channel Technology. After the memory is installed, the BIOS will automatically detect the specifications 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_2

DDR3_1

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.

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, first 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 configurations, 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.
