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 CPU
Please visit GIGABYTE's website for details on hardware installation.
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.
1-4 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.
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.
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.

The two memory sockets are divided into two channels and each channel has one memory socket as following:
Channel A: DDR4_A1
Channel B: DDR4_B1
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 memory modules, it is recommended that memory of
the same capacity, brand, speed, and chips be used.
1-5 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.
1-6 Back Panel Connectors
USB 2.0/1.1 Port
The USB port supports the USB 2.0/1.1 specication. Use this port for USB devices.
PS/2 Keyboard/Mouse Port
Use this port to connect a PS/2 mouse or keyboard.
DVI-D Port (Note 1) (Note 2)
The DVI-D port conforms to the DVI-D specication and supports a maximum resolution of 1920x1200@60 Hz
(the actual resolutions supported depend on the monitor being used). Connect a monitor that supports
DVI-D connection to this port.
HDMI Port (Note 1)
The HDMI port is HDCP 2.3 compliant and supports Dolby TrueHD and DTS HD
Master Audio formats. It also supports up to 192KHz/24bit 7.1-channel LPCM
audio output. You can use this port to connect your HDMI-supported monitor. The maximum supported
resolution is 4096x2160@60 Hz, but the actual resolutions supported are dependent on the monitor being
used.
After installing the HDMI device, make sure to set the default sound playback device to HDMI.
(The item name may differ depending on your operating system.)
•When removing the cable connected to a back panel connector, rst remove the cable from
your device and then remove it from the motherboard.
•When removing the cable, pull it straight out from the connector. Do not rock it side to side to
prevent an electrical short inside the cable connector.
