Memory configurations
Youmayinstall4GB,8GB16GB,and32GBunbufferedandECCandnon-ECCDDR4
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.
• 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(4DIMMs)oroverclockingcondition.
• 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.
