1.1.6 Onboard buttons and switches
Onboardbuttonsandswitchesallowyoutone-tuneperformancewhenworkingonabareor
open-casesystem.Thisisidealforoverclockersandgamerswhocontinuallychangesettings
toenhancesystemperformance.
• Refertosection1.1.8 Onboard LEDsfortheexactlocationoftheMem_LED.
• TheDRAMLEDalsolightsupwhentheDIMMisnotproperlyinstalled.Turnoffthe
systemandreinstalltheDIMMbeforeusingtheMemOK!IIfunction.
• TheMemOK!IIswitchdoesnotfunctionunderWindows
®
OSenvironment.
• Duringthetuningprocess,thesystemloadsandtestspretestproles.Ittakesabout
30secondsforthesystemtotestonesetofproles.Ifthetestfails,thesystem
rebootsandteststhenextsetofproles.Thesystemwillrebootmultipletimeswhen
training,oncethesystemhascompletedthetrainingprocesstheMem_LEDwillturn
off,pleaserefrainfromdoinganythingbeforetheMem_LEDturnsoff.
• Duetomemorytuningrequirement,thesystemautomaticallyrebootswheneach
proleistested.
• IfyouturnoffthecomputerandreplaceDIMMsduringthetuningprocess,thesystem
continuesmemorytuningafterturningonthecomputer.Tostopmemorytuning,turn
offthecomputerandunplugthepowercordforabout5–10seconds,thensetthe
MemOK!IIswitchtodisabled.
• EnsuretoreplacetheDIMMswithonesrecommendedintheMemoryQVL(Qualied
VendorsLists)atwww.asus.com.
• WerecommendthatyoudownloadandupdatetothelatestBIOSversionfrom
www.asus.comafterusingtheMemOK!IIfunction.

InstallingDIMMsthatarenotcompatiblewiththemotherboardmaycausesystem
bootfailure.Theswitchisenabledbydefault,allowingmemoryre-trainingwhenthe
motherboardisunresponsiveduetomemoryproblems.TheMem_LEDwilllightup
whilere-training,andturnoffwhenthere-trainingiscomplete.
