1.6 Headers
1. Clear RTC RAM (2-pin CLRTC)
ThisheaderallowsyoutocleartheRealTimeClock(RTC)RAMinCMOS.Youcan
cleartheCMOSmemoryofdate,time,andsystemsetupparametersbyerasingthe
CMOSRTCRAMdata.TheonboardbuttoncellbatterypowerstheRAMdatain
CMOS,whichincludesystemsetupinformationsuchassystempasswords.
To erase the RTC RAM:
1. TurnOFFthecomputerandunplugthepowercord.
2. Useametalobjectsuchasascrewdrivertoshortthetwopins.
3. PlugthepowercordandturnONthecomputer.
4. Holddownthe<Del>keyduringthebootprocessandenterBIOSsetuptore-
enter data.
• Ifthestepsabovedonothelp,removetheonboardbatteryandshortthetwopins
againtocleartheCMOSRTCRAMdata.AfterclearingtheCMOS,reinstallthe
battery.
• YoudonotneedtocleartheRTCwhenthesystemhangsduetooverclocking.For
systemfailureduetooverclocking,usetheCPUParameterRecall(C.P.R.)feature.
Shutdownandrebootthesystem,thentheBIOSautomaticallyresetsparameter
settingstodefaultvalues.
