1.4.2 Memory configurations

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.

• 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:

 - Installamaximumof3GBsystemmemoryifyouareusinga32-bitWindows®

 OS.

- Usea64-bitWindows®OSifyouwanttoinstall4GBormorememoryonthe

motherboard.

• ThismotherboarddoesnotsupportDIMMsmadeupof512Mb(64MB)chipsorless.

• Themaximum32GBmemorycapacitycanbesupportedwith16GBoraboveDIMMs.

ASUSwillupdatethememoryQVLoncetheDIMMsareavailableinthemarket.

• 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

lowerfrequencythanthevendor-markedvalue.Tooperateatthevendor-marked

oratahigherfrequency,refertosection2.5 Ai Tweaker menu for manual memory

frequencyadjustment.

• Forsystemstability,useamoreefcientmemorycoolingsystemtosupportafull

memoryload(2DIMMs)oroverclockingcondition.

• Refertowww.asus.comforthelatestMemoryQVL(QualiedVendorsList).

1.5 Expansion slots

Inthefuture,youmayneedtoinstallexpansioncards.Thefollowingsub-sectionsdescribe

the slots and the expansion cards that they support.

Unplugthepowercordbeforeaddingorremovingexpansioncards.Failuretodosomay

cause you physical injury and damage motherboard components.

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

seated on the slot.

5. Securethecardtothechassiswiththescrewyouremovedearlier.

6. Replacethesystemcover.

1.5.2 Configuring 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.
