InstallingDIMMsthatarenotcompatiblewiththemotherboardmaycausesystem
bootfailure.IfthesystemfailstobootduringPOSTstageandtheDRAM_LEDlights
continuously,presstheMemOK!buttonuntiltheDRAM_LEDstartsblinking.System
willbeginautomaticmemorycompatibilitytuningandrebootforsuccessfulboot.
• Refertosection1.1.8 Onboard LEDsfortheexactlocationoftheDRAM_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!function.
• TheMemOK!buttondoesnotfunctionunderWindows
®
OSenvironment.
• Duringthetuningprocess,thesystemloadsandtestsfailsafememorysettings.It
takesabout30secondsforthesystemtotestonesetoffailsafesettings.Ifthetest
fails,thesystemrebootsandteststhenextsetoffailsafesettings.Theblinkingspeed
oftheDRAM_LEDincreases,indicatingdifferenttestprocesses.
• Duetomemorytuningrequirement,thesystemautomaticallyrebootswheneach
timingsetistested.IftheinstalledDIMMsstillfailtobootafterthewholetuning
process,theDRAM_LEDlightscontinuously.ReplacetheDIMMswithones
recommendedintheMemoryQVL(QualiedVendorsLists)atwww.asus.com.
• 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.
• IfyoursystemfailstobootupduetoBIOSoverclocking,presstheMemOK!button
tobootandloadtheBIOSdefaultsettings.AmessagewillappearduringPOST
remindingyouthattheBIOShasbeenrestoredtoitsdefaultsettings.
• WerecommendthatyoudownloadandupdatetothelatestBIOSversionfrom
www.asus.comafterusingtheMemOK!function.
