Target Mac Pro Models

This 4GB DDR3 ECC RDIMM is built for Apple Mac Pro towers released in Mid 2010 and Mid 2012 with six-core or twelve-core Xeon processors. It matches the 1333MHz PC3-10600 speed and 1.50V voltage required by those systems. The registered design and 240-pin form factor align with the MacPro5,1 memory architecture.

Not for Non-Listed Macs

This module will not fit Mac Pro models outside the specified Mid 2010 and Mid 2012 six-core and twelve-core configurations. It is also unsuitable for any non-Apple system or laptop requiring standard unbuffered DDR3 DIMMs. Buyers needing higher capacity per slot or different memory speeds should look elsewhere.

ECC Registered DDR3 Specification

The decisive specification is the ECC Registered DDR3 1333MHz PC3-10600 240-pin RDIMM format. Only Mac Pro towers that explicitly support registered ECC memory at this speed can use this upgrade. Verify your model identifier is MacPro5,1 before purchasing.

Questions about this item

Does my Mac Pro need a specific processor for this 1333MHz ECC RDIMM to be recognised?

The module is validated for Mac Pro 5,1 systems running 2.4GHz Xeon E5645, 2.66GHz Xeon X5650, 3.06GHz Xeon X5675, 2.93GHz Xeon X5670 or 3.33GHz Xeon W3680 processors.

Will this 240-pin registered module work in the original memory slots of a Mid 2010 or Mid 2012 Mac Pro tower?

Yes, it is designed for the DDR3 RDIMM slots in Mac Pro models A1289 (EMC 2314-2 and EMC 2629) from Mid 2010 and Mid 2012.

How can I confirm the 4GB module is running at PC3-10600 speed with ECC active after installation?

Open System Report in macOS; the memory section will show 4GB DDR3 1333MHz ECC Registered for the installed slot.
