Chapter 1 Hardware Installation
1-1 Installation Precautions
The motherboard contains numerous delicate electronic circuits and components which can become
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.
•
•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.
•
•
•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
•If you use an adapter, extension power cable, or power strip, ensure to consult with its installation
and/or grounding instructions.

1-3 Installing 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.
•

•
standard requirements for the peripherals. If you wish to set the frequency beyond the standard
card, memory, hard drive, etc.
Installing the CPU
Locate the pin one (denoted by a small triangle) of the CPU socket and the CPU.
1-4 Installing the Memory
following:
•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
