1. Clear RTC RAM jumper (2-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. Short-circuitpin1-2withametalobjectorjumpercapforabout5-10seconds.
3. PlugthepowercordandturnONthecomputer.
4. Holddownthe<Delete>keyduringthebootprocessandenterBIOSsetuptore-enter
data.
ExceptwhenclearingtheRTCRAM,neverplaceametalobjectorjumpercaponthe
CLRTCjumper.Placingametalobjectorjumpercapwillcausesystembootfailure!
• Ifthestepsabovedonothelp,removetheonboardbatteryandplaceametalobject
orjumpercapagaintocleartheCMOSRTCRAMdata.AftertheCMOSclearance,
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C.P.R.(CPUParameterRecall)feature.
ShutdownandrebootthesystemsotheBIOScanautomaticallyresetparameter
settingstodefaultvalues.
• Duetothechipsetbehavior,ACpoweroffisrequiredtoenableC.P.R.function.You
mustturnoffandturnonthepowersupplyorunplugandplugthepowercordbefore
rebootingthesystem.
