Motherboard information
2.1 Before you proceed
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
CAUTION!
• Unplugthepowercordfromthewallsocketbeforetouchingany
component.
• Beforehandlingcomponents,useagroundedwriststraportouchasafely
groundedobjectorametalobject,suchasthepowersupplycase,toavoid
damaging them due to static electricity.
• HoldcomponentsbytheedgestoavoidtouchingtheICsonthem.
• Wheneveryouuninstallanycomponent,placeitonagroundedantistatic
pad or in the bag that came with the component.
• Beforeyouinstallorremoveanycomponent,ensurethattheATXpower
supply is switched off or the power cord is detached from the power
supply.Failuretodosomaycauseseveredamagetothemotherboard,
peripherals,orcomponents.
Main and Standby Power LEDs
The motherboard comes with one standby power LED and main power LED that
lightuptoindicatethatthesystemisON,insleepmode,orinsoft-offmode.This
is a reminder that you should shut down the system and unplug the power cable
beforeremovingorplugginginanymotherboardcomponent.Theillustrationbelow
shows the location of the onboard LEDs.

IMPORTANT:UnplugallpowercablesbeforeinstallingtheCPU.
CAUTION!
• Uponpurchaseofthemotherboard,ensurethatthePnPcapison
thesocketandthesocketcontactsarenotbent.Contactyourretailer
immediatelyifthePnPcapismissing,orifyouseeanydamagetothe
PnPcap/socketcontacts/motherboardcomponents.Themanufacturerwill
shoulderthecostofrepaironlyifthedamageisshipment/transit-related.
• Keepthecapafterinstallingthemotherboard.Themanufacturerwill
processReturnMerchandiseAuthorization(RMA)requestsonlyifthe
motherboardcomeswiththecapontheLGA1155socket.
• Theproductwarrantydoesnotcoverdamagetothesocketcontacts
resultingfromincorrectCPUinstallation/removal,ormisplacement/loss/
incorrectremovalofthePnPcap.

2.6 Jumpers
1. Clear RTC RAM (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 reenter data.
CAUTION!ExceptwhenclearingtheRTCRAM,neverremovethecapon
CLRTCjumperdefaultposition.Removingthecapwillcausesystemboot
failure!
NOTES:
• 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sothe
BIOScanautomaticallyresetparametersettingstodefaultvalues.
