Mac Pro 2010/2012 16GB ECC kit

This 16GB kit contains two 8GB DDR3 1333 ECC RDIMM modules built for the Mac Pro Mid 2010 and Mid 2012 models with 6-Core or 12-Core Xeon processors. The registered 240-pin DIMMs run at 1.50V and carry major-brand chips validated for Apple order numbers MD771LL/A and model ID MacPro5,1. Installation adds 16GB of error-correcting memory to the four-slot or eight-slot risers in those towers.

Suits owners of compatible Mac Pro towers

The kit is intended for users upgrading a Mac Pro Mid 2010 (6-Core or 12-Core) or Mid 2012 (6-Core or 12-Core) that accepts DDR3 1333 ECC registered memory. It will not fit Mac Pro models that use a different memory generation or form factor, nor standard desktop boards that require unbuffered non-ECC DIMMs. Builders needing higher capacity per module or a different voltage should look elsewhere.

DDR3 1333 ECC RDIMM 240-pin specification

The decisive specification is the DDR3 1333 (PC3-10600) ECC registered 240-pin RDIMM format. Only systems listed as compatible — MacPro5,1 with Xeon E5645, X5650, X5675, X5670 or W3680 processors — will recognise and run this kit at the rated speed and voltage. Any other platform lacking DDR3 ECC RDIMM support cannot use these modules.

Questions about this item

How can I confirm the 16GB DDR3 1333 ECC RDIMM kit is running correctly after installation in my Mac Pro?

Open About This Mac to verify 16GB appears, then run Apple Hardware Test or Apple Diagnostics for a full memory check.

What comes in the box and do I need anything else to install the 2x8GB 240-pin modules?

The kit includes two 8GB DDR3 1333 ECC registered DIMMs; no extra parts or tools are required for the Mac Pro memory bays.

Which capacity should I choose between the 16GB kit and other sizes for a Mac Pro 5,1 with Xeon 2.4 or 3.33GHz CPUs?

This 16GB (2x8GB) kit matches the qualified MD771LL/A configuration and works with all listed Xeon processors for those models.
