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.
Dual Channel Memory Conguration
This motherboard provides four 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 four memory sockets are divided into two channels and each channel has two memory sockets as following:
Channel A: DDR4_2, DDR4_4
Channel B: DDR4_1, DDR4_3
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.
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.
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.

Do not force the CPU into the CPU socket before the CPU socket locking lever is lifted up, or
damage to the CPU and CPU socket may occur.

The front panel design may differ by chassis. A front panel module mainly consists of power switch,
resetswitch,powerLED,harddriveactivityLED,speakerandetc.Whenconnectingyourchassis
front panel module to this header, make sure the wire assignments and the pin assignments are
matched correctly.
12) F_PANEL (Front Panel Header)
Connect the power switch, reset switch, speaker, chassis intrusion switch/sensor and system status indicator
on the chassis to this header according to the pin assignments below. Note the positive and negative pins
before connecting the cables.

system startup status by issuing a beep code. One single short beep
will be heard if no problem is detected at system startup.

panel audio module to this header. Make sure the wire assignments of the module connector match the
pin assignments of the motherboard header. Incorrect connection between the module connector and the
motherboard header will make the device unable to work or even damage it.
Some chassis provide a front panel audio module that has separated connectors on each wire
instead of a single plug. For information about connecting the front panel audio module that has
different wire assignments, please contact the chassis manufacturer.
