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 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 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.
A. Note the CPU Orientation
Note the alignment keys on the motherboard CPU socket and the notches on the CPU.
Do not remove the CPU socket cover before inserting the CPU. It may pop off from the load
plate automatically after you insert the CPU and close the load plate.

B. Installing the CPU
Follow the steps below to correctly install the CPU into the motherboard CPU socket.
Do not force to engage the CPU socket locking lever when the CPU is not installed correctly
as this would damage the CPU and CPU socket.

kCompletely lift up the CPU socket lock-
ing lever.
lWith your ngers, hold the plastic protec-
tive cover attached to the metal load plate
to lift open the metal load plate.
Hold the CPU with your ngers by the edges.
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.
Make sure the CPU is properly installed and
then close the load plate. Secure the socket
lever under its retention tab. The plastic
protective cover will pop off by itself and can
be removed.
* Always replace the plastic protective cover
when the CPU is not installed to protect the
CPU socket.
