Memory
Conguration
DIMMs reside on the
computer’s processor
board, which is laid out in
two congurations. Check
the illustrations on this
page to determine if you
have a single- or dual-
processor conguration.
Specications
DIMMs for Mac Pro (Early
2009) must t these
specications:
• PC3-8500,1066
MHz, DDR3 SDRAM
UDIMMs
• Error-correcting code
(ECC)
• 72-bit wide, 240-pin
ECC modules
• 18 memory ICs
maximum per UDIMM
DIMMs for Mac Pro (Mid
2010) must t these
specications:
• PC3-10600E,1333
MHz, DDR3 SDRAM
UDIMMs
• Error-correcting code
(ECC)
• 72-bit wide, 240-pin
ECC modules

Note: Memory from older
Apple computers is not
compatible with your
computer.
