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1.65Visrecommendedtoprotect

the CPU.

• 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:

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

OS.

b) Installa64-bitWindows

OSwhenyouwanttoinstall4GBormoreonthe

motherboard.

(MemorychipcapacitycountsinMegabit,8Megabit/Mb=1Megabyte/MB).

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

• AlwaysinstalltheDIMMSwiththesameCASLatency.Foranoptimumcompatibility,

we recommend that you install memory modules of the same version or data code

(D/C)fromthesamevendor.Checkwiththevendortogetthecorrectmemory

modules.
