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 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 certied computer technician.

1-3 Installing the CPU and CPU Cooler
Read the following guidelines before you begin to install the CPU:
• Make sure that the motherboard supports the CPU.
(Go to GIGABYTE's website for the latest CPU support list.)
• Always turn off the computer and unplug the power cord from the power outlet before installing
the CPU to prevent hardware damage.
• Locate the pin one of the CPU. The CPU cannot be inserted if oriented incorrectly. (Or you may
locate the notches on both sides of the CPU and alignment keys on the CPU socket.)
• Apply an even and thin layer of thermal grease on the surface of the CPU.
• Do not turn on the computer if the CPU cooler is not installed, otherwise overheating and dam-
age of the CPU may occur.
• Set the CPU host frequency in accordance with the CPU specications. It is not recommended
that the system bus frequency be set beyond hardware specications since it does not meet the
standard requirements for the peripherals. If you wish to set the frequency beyond the standard
specications, please do so according to your hardware specications including the CPU, graphics card, memory, hard drive, etc.

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.
•
Populating DDR2 and DDR3 memory modules simultaneously is not supported. To ensure memory
compatibility, be sure to use the memory modules on the memory support list at GIGABYTE's website.
1-4-1 Dual Channel Memory Conguration
This motherboard provides two DDR2 and two DDR3 memory sockets and supports Dual Channel Technology.
The two DDR3 memory sockets (DDR3_1, DDR3_2) are divided into two channels and each channel has one
memory socket as following:
Channel 0: DDR3_1
Channel 1: DDR3_2
The two DDR2 memory sockets (DDR2_1, DDR2_2) are divided into two channels and each channel has one
memory socket as following:
Channel 0: DDR2_1
Channel 1: DDR2_2
DDR2_1
DDR3_1
DDR2_2
DDR3/DDR2 Dual Channel Memory Conguration:
Due to chipset limitations, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one DDR3/DDR2 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.
DDR3_2
1-5 Installing an Expansion Card
Read the following guidelines before you begin to install an expansion card:
• Make sure the motherboard supports the expansion card. Carefully read the manual that came
with your expansion card.
• Always turn off the computer and unplug the power cord from the power outlet before installing
an expansion card to prevent hardware damage.

• When removing the cable connected to a back panel connector, rst remove the cable from your
device and then remove it from the motherboard.
• When removing the cable, pull it straight out from the connector. Do not rock it side to side to
prevent an electrical short inside the cable connector.

Read the following guidelines before connecting external devices:
• First make sure your devices are compliant with the connectors you wish to connect.
• Before installing the devices, be sure to turn off the devices and your computer. Unplug the
power cord from the power outlet to prevent damage to the devices.
• After installing the device and before turning on the computer, make sure the device cable has
been securely attached to the connector on the 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 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.

3/4) CPU_FAN/SYS_FAN (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN) and a 3-pin (SYS_FAN) system fan header.
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 conguration jumper blocks. Do not place a jumper cap on the
headers.
5) FDD (Floppy Disk Drive Connector)
This connector is used to connect a oppy disk drive. The types of oppy disk drives supported are:
360 KB, 720 KB, 1.2 MB, 1.44 MB, and 2.88 MB. Before connecting a oppy disk drive, be sure to locate
pin 1 of the connector and the oppy disk drive cable. The pin 1 of the cable is typically designated by
a stripe of different color. For purchasing the optional oppy disk drive cable, please contact the local
dealer.
