1.4.1 Overview
ThismotherboardcomeswithfourDoubleDataRate3(DDR3)DualInlineMemoryModule
(DIMM)sockets.ThegureillustratesthelocationoftheDDR3DIMMsockets:
Channel Sockets
ChannelA DIMM_A1andDIMM_A2
ChannelB DIMM_B1andDIMM_B2
1.4.2 Memory configurations
Youmayinstall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.
• AccordingtoIntelCPUspec,DIMMvoltagebelow1.65Visrecommendedtoprotect
theCPU.
• 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
