Mac Pro (Late 2013) memory kit

This 32GB kit contains two 16GB DDR3 1866/1867MHz ECC registered DIMMs built for the Mac Pro (Late 2013, cylinder). It targets owners of MacPro6,1 systems who need to expand memory capacity for heavier workloads.

Fits the four-slot Mac Pro architecture

Each module uses the 240-pin RDIMM form factor at 1.50V and is validated for the Xeon E5-1620v2, E5-1650v2, E5-1680v2 and E5-2697v2 processors listed by Apple. The registered design with ECC maintains data integrity across all populated slots.

Major-brand chips and lifetime support

Modules are assembled with major-brand chipsets and tested to A-Tech quality standards. The kit ships with a lifetime warranty and access to US-based technical support for installation questions.

Questions about this item

How does the DDR3 1866 MHz speed affect sustained workloads on my Mac Pro?

The modules run at DDR3 1866 MHz (PC3-14900) with 1.50 V, delivering the rated throughput continuously within Apple's thermal design for the Late 2013 Mac Pro.

What heat or noise impact should I expect from these RDIMMs during all-day operation?

No heat spreaders are fitted; the registered ECC chips operate at standard DDR3 voltage so they add minimal heat and no audible noise inside the Mac Pro's enclosure.

Which Mac Pro model and processor combinations are required for this 32 GB kit to work?

This kit is validated for MacPro6,1 (A1481 EMC 2630) with Xeon E5-1620 v2, E5-1650 v2, E5-1680 v2 or E5-2697 v2 CPUs and requires the four-slot memory riser.
