Mac Pro 12-Core 2010/2012 memory kit

This A-Tech kit supplies 32GB of DDR3 1333MHz ECC UDIMM memory across eight 4GB modules. It is built for the Mac Pro 12-Core models released in 2010 and 2012, matching the 240-pin unbuffered ECC specification those systems require. The modules run at 1.50V and use major-brand chips tested to PC3-10600 speed.

Suits owners of MacPro5,1 towers needing maximum

The kit fits Apple model IDs MacPro5,1 and order numbers MD771LL/A, covering the 2.4GHz Xeon E5645, 2.66GHz Xeon X5650, 2.93GHz Xeon X5670 and 3.06GHz Xeon X5675 configurations. It does not suit Mac Pro models with fewer than eight memory slots, systems that require registered DIMMs, or any machine that does not accept unbuffered ECC UDIMM modules.

Eight-module 32GB capacity fills every slot

The 8x4GB arrangement occupies all eight DIMM positions in the 12-Core Mac Pro, delivering the full 32GB capacity in a single matched kit. This eliminates the need to mix separate packs and ensures uniform rank configuration across the memory controller.

Questions about this item

What is the maximum memory capacity this 32 GB DDR3 1333 MHz kit fills on a Mac Pro 12-Core 2010/2012?

The kit supplies 32 GB using eight 4 GB DDR3 1333 MHz ECC UDIMM modules, matching the 12-core Mac Pro's full 32 GB limit.

How much power does the 1.50 V DDR3 ECC UDIMM kit draw when the Mac Pro runs continuously?

Each module operates at the standard DDR3 1.50 V; total draw depends on the Mac Pro's memory controller and workload, not on the kit alone.

Which Mac Pro model identifiers must I already own for this 240-pin DDR3 ECC kit to be compatible?

The kit is validated for MacPro5,1 systems with Apple order numbers MD771LL/A and model numbers A1289 (EMC 2314-2 / 2629).
