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, 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,
keepyourhandsdryandrsttouchametalobjecttoeliminatestaticelectricity.
•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,pleaseconsultacertiedcomputertechnician.
•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 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.
•AccordingtoCPUspecications,ifonlyonememorymoduleistobeinstalled,besuretoinstall
it in the SODIMM_1 slot.
DualChannelMemoryConguration
This motherboard provides two memory sockets and supports Dual Channel Technology. After the memory
isinstalled,theBIOSwillautomaticallydetectthespecicationsandcapacityofthememory.EnablingDual
Channel memory mode will double the original memory bandwidth.
The two memory sockets are divided into two channels and each channel has one memory socket as following:
Channel A: SODIMM_1
Channel B: SODIMM_2
Due to SoC limitations, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one 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 for optimum performance.
1-4 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.

2/3) CPU_FAN/SYS_FAN (Fan Headers)
All fan headers on this motherboard are 4-pin. 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 speed control function requires the use of a 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.
