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.

1-4 Installing the Memory
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notchesonbothsidesoftheCPUandalignmentkeysontheCPUsocket.)
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.

1-5 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.

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 and installed in the same colored sockets.
For optimum performance, when enabling Dual Channel mode with two memory modules, be sure to

Quick Buttons
This motherboard has 3 quick buttons: power button, reset button and clear CMOS button. The power button
and reset button allow users to quickly turn on/off or reset the computer in an open-case environment when
they want to change hardware components or conduct hardware testing.
Use this button to clear the BIOS
congurationandresettheCMOSvaluestofactorydefaultswhenneeded.
PW_SW: Power Button
RST_SW: ResetButton
CMOS_SW: Clear CMOS Button
Always turn off your computer and unplug the power cord from the power outlet before clearing
the CMOS values.
NOTE: Do not use the clear CMOS button when the system is on, or the system may shutdown
and data loss or damage may occur.

ThefrontpanelaudioheadersupportsIntelHighDenitionaudio(HD)andAC'97audio.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.
For HD Front Panel Audio:
For AC'97 Front Panel Audio:
The front panel audio header supports HD audio by default.
Audio signals will be present on both of the front and back panel audio connections simultaneously.
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.

14) 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 Status LED
S0 On
S3/S4/S5 Off
PW(PowerSwitch,Red):
Connects to the power switch on the chassis front panel. You may
congurethewaytoturnoffyoursystemusingthepowerswitch(refer
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.
PLED/PWR_LED (PowerLED,Yellow/Purple):
Connects to the power status indicator
on the chassis front panel. The LED is on
when the system is operating. The LED is
off when the system is in S3/S4 sleep state
orpoweredoff(S5).
HD (HardDriveActivityLED,Blue):
Connects to the hard drive activity LED on the chassis front panel. The LED is on when the hard drive is
reading or writing data.
RES (ResetSwitch,Green):
Connects to the reset switch on the chassis front panel. Press the reset switch to restart the computer if the
computerfreezesandfailstoperformanormalrestart.
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.
