• InsingleVGAcardmode,usethePCIe3.0/2.0x16_1slot(gray)foraPCIExpress
x16graphicscardtogetbetterperformance.
• WerecommendthatyouprovidesufcientpowerwhenrunningCrossFireX™mode.
• ConnectachassisfantothemotherboardconnectorlabeledCHA_FAN1/2when
usingmultiplegraphicscardsforbetterthermalenvironment.
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.
