2-1 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, make sure the chassis is suitable for the motherboard.

•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 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 connecting or 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 or wet 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 certied computer technician.

•If you use an adapter, extension power cable, or power strip, ensure to consult with its installation

and/or grounding instructions.

2-3 Installing the CPU

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.

•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 specications. It is not recommended

that the system bus frequency be set beyond hardware specications since it does not meet the

standard requirements for the peripherals. If you wish to set the frequency beyond the standard

specications, please do so according to your hardware specications including the CPU, graphics

card, memory, hard drive, etc.

Installing the CPU

Completely lift up the CPU socket locking lever. Locate the pin one (denoted by a small triangle) of the CPU

socket and the CPU. Once the CPU is positioned into its socket, place one nger down on the middle of the

CPU, lowering the locking lever and latching it into the fully locked position.

Do not force the CPU into the CPU socket before the CPU socket locking lever is lifted up, or

damage to the CPU and CPU socket may occur.

&Please visit GIGABYTE's website for details on hardware installation.
