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
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.
Please visit GIGABYTE's website for details on hardware installation.

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
PS/2 Keyboard and PS/2 Mouse Port
Usetheupperport(green)toconnectaPS/2mouseandthelowerport(purple)toconnectaPS/2keyboard.
DVI-D Port (Note)
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
TheHDMIportisHDCPcompliantandsupportsDolbyTrueHDandDTSHD
MasterAudio formats. It alsosupportsupto 192KHz/24bit 8-channel LPCM
audiooutput.YoucanusethisporttoconnectyourHDMI-supportedmonitor.Themaximumsupported
resolutionis4096x2160@24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.)
(Note) TheDVI-DportdoesnotsupportD-Subconnectionbyadapter.
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DDR4memorysocketsaredividedintotwochannelsandeachchannelhasonememorysocketas
following:
ChannelA:DDR4_2
ChannelB:DDR4_1
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.
