1.6 Jumpers
1. Clear RTC RAM (3-pin CLRTC)
Thisjumper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. Movethejumpercapfrompins1-2(default)topins2-3.Keepthecaponpins2-3
forabout5-10seconds,thenmovethecapbacktopins1-2.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.
ExceptwhenclearingtheRTCRAM,neverremovethecaponCLRTCjumperdefault
position.Removingthecapwillcausesystembootfailure!
• Ifthestepsabovedonothelp,removetheonboardbatteryandmovethejumper
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.
