Overview

ThismotherboardcomeswithtwoDoubleDataRate4(DDR4)DualInlineMemoryModule

(DIMM)sockets.ThegureillustratesthelocationoftheDDR4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.

• DDR42666MHzandhighermemorymoduleswillrunatmaximum2666MHzonIntel



8thGeneration6-coreorhigherprocessors.

• 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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.

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

memoryload(2DIMMs).
