Chapter 1 Hardware Installation
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 components such as a motherboard, CPU or memory. If you do not have an ESD wrist strap, keep your hands dry and first 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 supply 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 hardware 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 system 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 certified computer technician.

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.
•Mixed mode, populating DDR2 and DDR3 memory modules simultaneously is not supported.
1-4-1 Dual Channel Memory Configuration
This motherboard provides four DDR2 and 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 four DDR2 memory sockets (DDRII1, DDRII2, DDRII3, and DDRII4) are divided into two channels and each channel has two memory sockets as following:
Channel 0: DDRII1, DDRII2
Channel 1: DDRII3, DDRII4

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 (400W 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 main power connector is compatible with power supplies with 2x10 power connectors. When using a 2x12 power supply, remove the protective cover from the main power connector on the motherboard. Do not insert the power supply cable into pins under the protective cover when using a 2x10 power supply.

3/4/5) CPU_FAN/SYS_FAN1/SYS_FAN2/PWR_FAN (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN), a 3-pin (SYS_FAN1) and a 4-pin (SYS_FAN2) system fan headers, and a 3-pin power fan header (PWR_FAN). Each fan header supplies a +12V power voltage and possesses a foolproof insertion design. When connecting a fan cable, be sure to connect it in the correct orientation. Most fans are designed with color-coded power connector wires. A red power connector wire indicates a positive connection and requires a +12V voltage. 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.
