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:
- 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512Mb(64MB)chipsorless.

1.4.1 Overview
ThismotherboardcomeswithfourDoubleDataRate3(DDR3)DualInlineMemoryModules
(DIMM)sockets.
ADDR3modulehasthesamephysicaldimensionsasaDDR2DIMMbutisnotched
differentlytopreventinstallationonaDDR2DIMMsocket.DDR3modulesaredevelopedfor
better performance with less power consumption.
