Compatibility & capacity

This 32GB kit contains four 8GB DDR3 1333MHz ECC registered DIMMs built for the Mac Pro Mid 2010 and Mid 2012 with six or twelve cores. It matches Apple order numbers MD771LL/A and model identifier MacPro5,1.

Who it suits

The modules suit owners of those towers who want the full 32GB using all four slots with registered ECC memory. It is not for anyone whose Mac Pro uses a different model identifier or requires unbuffered DIMMs.

Deciding specification

The registered ECC RDIMM form factor with a 240-pin DDR3 1333MHz interface is the single spec that determines whether the memory will be accepted by the Mac Pro memory controller.

Perguntas sobre este artigo

How does the 32GB capacity change everyday performance on a 2010 or 2012 Mac Pro?

Filling all four slots with 8GB modules gives the maximum 32GB the firmware recognises, letting the Xeon CPUs keep large datasets in memory instead of swapping to disk.

What does the DDR3 1333 PC3-10600 rating mean for actual throughput on these Mac Pros?

The memory controller on the supported Xeons tops out at 1333 MHz, so the kit runs at its rated 10600 MB/s peak bandwidth without down-clocking.

Will the 240-pin ECC registered sticks fit the Mac Pro memory tray without adapters?

Yes, the RDIMM form factor matches the factory tray slots exactly; the modules seat directly in the four user-accessible DIMM bays.
