Safety information
Electrical safety
• To prevent electrical shock hazard, disconnect the power cable from the electrical outlet
before relocating the system.
• When adding or removing devices to or from the system, ensure that the power cables
for the devices are unplugged before the signal cables are connected. If possible,
disconnect all power cables from the existing system before you add a device.
• Before connecting or removing signal cables from the motherboard, ensure that all
power cables are unplugged.
• Seek professional assistance before using an adapter or extension cord. These devices
could interrupt the grounding circuit.
• Ensure that your power supply is set to the correct voltage in your area. If you are not
sure about the voltage of the electrical outlet you are using, contact your local power
company.
• If the power supply is broken, do not try to x it by yourself. Contact a qualied service
technician or your retailer.
Operation safety
• Before installing the motherboard and adding devices on it, carefully read all the manuals
that came with the package.
• Before using the product, ensure all cables are correctly connected and the power
cables are not damaged. If you detect any damage, contact your dealer immediately.
• To avoid short circuits, keep paper clips, screws, and staples away from connectors,
slots, sockets and circuitry.
• Avoid dust, humidity, and temperature extremes. Do not place the product in any area
where it may become wet.
• Place the product on a stable surface.
• If you encounter technical problems with the product, contact a qualied service
technician or your retailer.

1.1 Before you proceed
Take note of the following precautions before you install motherboard components or change
any motherboard settings.
• Unplugthepowercordfromthewallsocketbeforetouchinganycomponent.
• Beforehandlingcomponents,useagroundedwriststraportouchasafelygrounded
objectorametalobject,suchasthepowersupplycase,toavoiddamagingthemdue
to static electricity.
• HoldcomponentsbytheedgestoavoidtouchingtheICsonthem.
• Wheneveryouuninstallanycomponent,placeitonagroundedantistaticpadorinthe
bag that came with the component.
• Beforeyouinstallorremoveanycomponent,ensurethattheATXpowersupplyis
switched off or the power cord is detached from the power supply. Failure to do so
maycauseseveredamagetothemotherboard,peripherals,orcomponents.
1.2 Motherboard overview
Beforeyouinstallthemotherboard,studythecongurationofyourchassistoensurethatthe
motherboardtsintoit.
Ensurethatyouunplugthepowercordbeforeinstallingorremovingthemotherboard.
Failure to do so can cause you physical injury and damage motherboard components.
1.2.1 Placement direction
Wheninstallingthemotherboard,ensurethatyouplaceitintothechassisinthecorrect
orientation. The edge with external ports goes to the rear part of the chassis as indicated in
the image below.

1-2 Chapter 1: Product introduction

Place this side towards
the rear of the chassis
1.2.2 Screw holes
Place four screws into the holes indicated by circles to secure the motherboard to the
chassis.
Donotovertightenthescrews!Doingsocandamagethemotherboard.

Youmayinstall1GB,2GB,4GB,and8GBunbufferednon-ECCDDR3DIMMsintotheDIMM
sockets.
• YoumayinstallvaryingmemorysizesinChannelAandChannelB.Thesystem
mapsthetotalsizeofthelower-sizedchannelforthedual-channelconguration.Any
excessmemoryfromthehigher-sizedchannelisthenmappedforsingle-channel
operation.
• DuetoIntel®chipsetlimitations,DDR31600MHzandhighermemorymoduleson
XMPmodewillrunatthemaximumtransferrateofDDR31600MHz.
• AlwaysinstallDIMMswiththesameCASlatency.Foroptimalcompatibility,we
recommendthatyouinstallmemorymodulesofthesameversionordatecode(D/C)
fromthesamevendor.Checkwiththeretailertogetthecorrectmemorymodules.
• Duetothememoryaddresslimitationon32-bitWindows®OS,whenyouinstall4GB
ormorememoryonthemotherboard,theactualusablememoryfortheOScanbe
about3GBorless.Foreffectiveuseofmemory,werecommendthatyoudoanyofthe
following:
- Useamaximumof3GBsystemmemoryifyouareusinga32-bitWindows®OS.
 - Installa64-bitWindows®OSifyouwanttoinstall4GBormoreonthe
motherboard.
• ThismotherboarddoesnotsupportDIMMsmadeupof512megabits(Mb)chipsor
less.
• Memorymoduleswithmemoryfrequencyhigherthan2133MHzanditscorresponding
timingortheloadedX.M.P.ProleisnottheJEDECmemorystandard.Thestability
andcompatibilityofthesememorymodulesdependontheCPU’scapabilitiesand
otherinstalleddevices.
• Themaximum16GBmemorycapacitycanbesupportedwith8GBoraboveDIMMs.
ASUSwillupdatethememoryQVLoncetheDIMMsareavailableinthemarket.
AccordingtoIntel®CPUspec,DIMMvoltagebelow1.65Visrecommendedtoprotectthe
CPU.

1-8 Chapter 1: Product introduction
• ThedefaultmemoryoperationfrequencyisdependentonitsSerialPresenceDetect
(SPD),whichisthestandardwayofaccessinginformationfromamemorymodule.
Underthedefaultstate,somememorymodulesforoverclockingmayoperateata

1.5.1 Installing an expansion card
To install an expansion card:
1. Beforeinstallingtheexpansioncard,readthedocumentationthatcamewithitand
make the necessary hardware settings for the card.
2. Removethesystemunitcover(ifyourmotherboardisalreadyinstalledinachassis).
3. Removethebracketoppositetheslotthatyouintendtouse.Keepthescrewforlater
use.
4. Alignthecardconnectorwiththeslotandpressrmlyuntilthecardiscompletely

5. Securethecardtothechassiswiththescrewyouremovedearlier.
6. Replacethesystemcover.
1.5.2 Conguringanexpansioncard
Afterinstallingtheexpansioncard,congureitbyadjustingthesoftwaresettings.
1. TurnonthesystemandchangethenecessaryBIOSsettings,ifany.SeeChapter2for
informationonBIOSsetup.
2. AssignanIRQtothecard.
3. Installthesoftwaredriversfortheexpansioncard.
WhenusingPCIcardsonsharedslots,ensurethatthedriverssupport“ShareIRQ”orthat
thecardsdonotneedIRQassignments.Otherwise,conictswillarisebetweenthetwoPCI
groups,makingthesystemunstableandthecardinoperable.
