Apple Mac Pro - Installing Memory (RAM)

37Chapter 3 Making a Good Thing Better
Installing Memory
YourMacProcomeswithaminimumof8GBofmemoryinthesingle-processormodel
installedas2GBunbueredECCdualinlinememorymodules(UDIMMs).
AllinstalledUDIMMsmustmeetthesespecications:
Â PC3-10600E,1333MHz,DDR3SDRAMUDIMMs
Â Error-correctingcode(ECC)
Â 72-bitwide,240-pinECCmodules
Â 36ICsmaximumperECCUDIMM
NOTICE: ApplerecommendsthatyouuseApple-approvedDIMMs.DIMMsfromolder
MaccomputerscannotbeusedinyourMacPro.YoucanpurchaseApple-branded
memoryonlinefromtheAppleStoreatwww.apple.com/store.
WhenpurchasingDIMMsforuseinMaccomputers,makesurethatthememoryvendor
conformstotheJointElectronDeviceEngineeringCouncil(JEDEC)specication.Check
withyourmemoryvendortoensurethattheDIMMssupportthecorrecttimingmodes
andthattheSerialPresenceDetect(SPD)featurehasbeenprogrammedproperly,as
describedintheJEDECspecication.
Note: AlthoughthememoryspeedoftheUDIMMSis1333MHz,theywilloperateat
1066MHzor1333MHz,dependingontheprocessorinthecomputer.
