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,

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.

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.

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.

DualChannelMemoryConguration

This motherboard provides two memory sockets and supports Dual Channel Technology. After the memory

isinstalled,theBIOSwillautomaticallydetectthespecicationsandcapacityofthememory.EnablingDual

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 CPU 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 or four memory modules, it is recommended that memory

of the same capacity, brand, speed, and chips be used.

DC In Power Connector

Connect the DC power to this port. This port supports 12V/19V/24V power adapter of up to 150w. Note:

The DC power jack cannot be used with the 4-pin ATX 12V power connector simultaneously as a source

of power input.

USB 3.1 Gen 1 Port

The USB 3.1 Gen 1 port supports the USB 3.1 Gen 1specicationandiscompatibletotheUSB2.0

specication.UsethisportforUSBdevices.

D-Sub Port

The D-Sub port supports a 15-pin D-Sub connector and supports a maximum resolution of 1920x1200@60 Hz

(the actual resolutions supported depend on the monitor being used). Connect a monitor that supports D-Sub

connection to this port.
