Mac Pro 2010/2012 16 GB Upgrade

This 16 GB DDR3 1333 ECC registered DIMM is built for Mac Pro towers released in mid 2010 and mid 2012 with six or twelve-core Xeon processors. It plugs into the 240-pin memory slots of MacPro5,1 systems carrying model IDs A1289 EMC 2314-2 or EMC 2629. The module matches Apple order numbers MD771LL/A and BTO/CTO configurations. It is not for machines that require unbuffered non-ECC memory or a different DDR generation.

Sustained Load Behaviour

Registered ECC circuitry corrects single-bit errors and reduces electrical load on the memory controller during long rendering, virtualisation or scientific workloads. The 1.50 V modules maintain stable timing at PC3-10600 speeds across all populated slots. Builders who need higher frequencies or lower latency than DDR3 1333 provides should look elsewhere.

Pre-Install Checks

Verify that your Mac Pro is a Mid 2010 or Mid 2012 tower with Xeon E5645, X5650, X5675, X5670, or W3680 processors. Confirm the system recognises 4Rx4 registered DIMMs and that enough 240-pin slots remain free for the desired capacity. This module will not fit laptops, iMacs, or Mac Pro models outside the listed years and CPU configurations.

Questions about this item

How much power does the 1.50V DDR3 1333 ECC RDIMM draw when the Mac Pro runs all day?

The module operates at 1.50V DDR3 standard voltage; actual system power draw depends on the Mac Pro's overall workload and the number of modules installed.

What must the buyer already own for this 240-Pin ECC Registered memory to work?

A Mac Pro (Mid 2010 or Mid 2012, 6-Core or 12-Core) with model ID MacPro5,1 and compatible Xeon processors such as 2.4GHz E5645 or 3.33GHz W3680.

Will this 16GB PC3-10600 4Rx4 module work alongside the original 2GB or 4GB DDR3 sticks in a 2010 Mac Pro?

Yes, the Mac Pro 5,1 supports mixed capacities; populate the four slots per CPU tray in matched sets for optimal quad-channel operation.
