1-1 Installation Precautions

The motherboard contains numerous delicate electronic circuits and components which can

become damaged as a result of electrostatic discharge (ESD). Prior to installation, carefully read

the user's manual and follow these procedures:

• Prior to installation, do not remove or break motherboard S/N (Serial Number) sticker or

warranty sticker provided by your dealer. These stickers are required for warranty validation.

• Always remove the AC power by unplugging the power cord from the power outlet before

installing or removing the motherboard or other hardware components.

• When connecting hardware components to the internal connectors on the motherboard,

make sure they are connected tightly and securely.

• When handling the motherboard, avoid touching any metal leads or connectors.

• It is best to wear an electrostatic discharge (ESD) wrist strap when handling electronic com-

ponents such as a motherboard, CPU or memory. If you do not have an ESD wrist strap,

keep your hands dry and rst touch a metal object to eliminate static electricity.

• Prior to installing the motherboard, please have it on top of an antistatic pad or within an

electrostatic shielding container.

• Before unplugging the power supply cable from the motherboard, make sure the power sup-

ply has been turned off.

• Before turning on the power, make sure the power supply voltage has been set according to

the local voltage standard.

• Before using the product, please verify that all cables and power connectors of your hard-

ware components are connected.

• To prevent damage to the motherboard, do not allow screws to come in contact with the

motherboard circuit or its components.

• Make sure there are no leftover screws or metal components placed on the motherboard or

within the computer casing.

• Do not place the computer system on an uneven surface

.

• Do not place the computer system in a high-temperature environment.

• Turning on the computer power during the installation process can lead to damage to sys-

tem components as well as physical harm to the user.

• If you are uncertain about any installation steps or have a problem related to the use of the

product, please consult a certied computer technician.

1-3 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.

1-3-1 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 A: SODIMMA
Channel B: DIMM1B, DIMM2B

SODIMMA

SODIMMB

1-3-2 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.
Be sure to install DDR3 DIMMs on this motherboard.

Installation Step:

Step 1. Align the memory with the DIMM module and insert the DIMM memory module into the DIM slot.
Please note that memory module has a foolproof insertion design. A memory module can be
installed In only one direction.

Step 2. Push down the memory and seat it rmly.

Step 3. Reverse the installation steps when you wish to remove the DIMM module.

1/2) ATX/ATX_12V (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 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.

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.

2/3) FAN1/FAN2 (CPU Fan/System Fan Headers)

The motherboard has a 4-pin CPU fan header (FAN1), a 4-pin (FAN2) system fan headers. 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.

• Be sure to connect fan cables to the fan headers to prevent your CPU and system from over­heating. Overheating may result in damage to the CPU or the system may hang.

• These fan headers are not conguration jumper blocks. Do not place a jumper cap on the

headers.

11) BATTERY (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 bat-

tery 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.

12) CLR_CMOS (Clearing CMOS Jumper)

Use this jumper to clear the CMOS values (e.g. date information and BIOS congurations) and reset

the CMOS values to factory defaults. To clear the CMOS values, place a jumper cap on the two pins to
temporarily short the two pins or use a metal object like a screwdriver to touch the two pins for a few

seconds.

1-2 Close: Normal operation (Default setting)

2-3 Close: Clear CMOS data)

• Always turn off your computer and unplug the power cord from the power outlet before clearing the CMOS

values.

• After clearing the CMOS values and before turning on your computer, be sure to remove the jumper cap from

the jumper. Failure to do so may cause damage to the motherboard.

• After system restart, go to BIOS Setup to load factory defaults (select Load Optimized Defaults) or manually

congure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS congurations).
