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.

1-3 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 damage of the CPU may occur.

Set the CPU host frequency in accordance with the CPU specifications. It is not recommended that the system bus frequency be set beyond hardware specifications since it does not meet the standard requirements for the peripherals. If you wish to set the frequency beyond the standard specifications, please do so according to your hardware specifications including the CPU, graphics card, memory, hard drive, etc.

1-3-1 Installing the CPU

A. Locate the alignment keys on the motherboard CPU socket and the notches on the CPU.

B. Follow the steps below to correctly install the CPU into the motherboard CPU socket.

Before installing the CPU, make sure to turn off the computer and unplug the power cord from the power outlet to prevent damage to the CPU.

CPU Socket Lever

Step 1:

Completely raise the CPU socket lever.

Step 3:

Remove the protective socket cover from the load plate. (To protect the CPU socket, always replace the protective socket cover when the CPU is not installed.)

Step 5:

Once the CPU is properly inserted, replace the load plate and push the CPU socket lever back into its locked position.

Step 2:

Lift the metal load plate from the CPU socket. (DO NOT touch socket contacts.)

Step 4:

Hold the CPU with your thumb and index fingers. Align the CPU pin one marking (triangle) with the pin one corner of the CPU socket (or you may align the CPU notches with the socket alignment keys) and gently insert the CPU into position.

Push Pin

Step 1:

Apply an even and thin layer of thermal grease on the surface of the installed CPU.

Step 3:

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 5:

After the installation, check the back of the motherboard. If the push pin is inserted as the picture above, the installation is complete.

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 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 Configuration

This motherboard provides four DDR2 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 are divided into two channels and each channel has two memory sockets as following:

Channel 0: DDR2_1, DDR2_2 Channel 1: DDR2_3, DDR2_4

Due to chipset limitation, read the following guidelines before installing the memory in Dual Channel mode. 1. Dual Channel mode cannot be enabled if only one DDR2 memory module is installed.

2. When enabling Dual Channel mode with two or four memory modules, it is recommended that memory of the same capacity, brand, speed, and chips be used and installed in the same colored DDR2 sockets for optimum performance.

When memory modules of different capacity and chips are installed, a message which says memory is operating in Flex Memory Mode will appear during the POST. Intel® Flex Memory Technology offers greater flexibility to upgrade by allowing different memory sizes to be populated and remain in Dual Channel mode/performance.

1-4-2 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. DDR2 DIMMs are not compatible to DDR DIMMs. Be sure to install DDR2 DIMMs on this motherboard.

Notch

DDR2 DIMM

A DDR2 memory module has a notch, so it can only fit in one direction. Follow the steps below to correctly install your memory modules in the memory sockets.

Step 1:

Note the orientation of the memory module. Spread the retaining clips at both ends of the memory socket. Place the memory module on the socket. As indicated in the picture on the left, place your fingers on the top edge of the memory, push down on the memory and insert it vertically into the memory socket.

Step 2:

The clips at both ends of the socket will snap into place when the memory module is securely inserted.

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.

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.
