• 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.Tooperateatthevendor-marked
oratahigherfrequency,refertosection2.5 Ai Tweaker menu for manual memory

• 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
