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.

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

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.

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.

Completely lift up the

CPU socket locking lever

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.

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.

The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not connected,

the computer will not start.

To meet expansion requirements, it is recommended that a power supply that can withstand high

power consumption be used (500W or greater). If a power supply is used that does not provide the

required power, the result can lead to an unstable or unbootable system.

connector wire is the ground wire). The speed control function requires the use of a fan with fan speed control

design.

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.

15) 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.

•PW (Power Switch, Red):

Connects to the power switch on the chassis front panel. You may

to Chapter 2, "BIOS Setup," "Power," for more information).

•SPEAK (Speaker, Orange):

Connects to the speaker on the chassis front panel. The system reports

system startup status by issuing a beep code. One single short beep

will be heard if no problem is detected at system startup.

•CI (Chassis Intrusion Header, Gray):

Connects to the chassis intrusion switch/sensor on the chassis that can detect if the chassis cover has

been removed. This function requires a chassis with a chassis intrusion switch/sensor.

•NC (Orange): No Connection.

17) BAT (Battery)

 Thebatteryprovidespowertokeepthevalues(suchasBIOScongurations,date,andtimeinformation)

in the CMOS when the computer is turned off. Replace the battery when the battery voltage drops to a low

level, or the CMOS values may not be accurate or may be lost.

You may clear the CMOS values by removing the battery:

1. Turn off your computer and unplug the power cord.

2. Gently remove the battery from the battery holder and wait for one minute. (Or use a

metal object like a screwdriver to touch the positive and negative terminals of the battery

holder, making them short for 5 seconds.)

3. Replace the battery.

4. Plug in the power cord and restart your computer.

•Always turn off your computer and unplug the power cord before replacing the battery.

•Replacethebatterywithanequivalentone.Damagetoyourdevicesmayoccurifthebatteryis

replaced with an incorrect model.

•Contact the place of purchase or local dealer if you are not able to replace the battery by yourself

or uncertain about the battery model.

•When installing the battery, note the orientation of the positive side (+) and the negative side (-)

of the battery (the positive side should face up).

•Used batteries must be handled in accordance with local environmental regulations.

16) F_AUDIO (Front Panel Audio Header)

 ThefrontpanelaudioheadersupportsHighDenitionaudio(HD).Youmayconnectyourchassisfront

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.
