Mac Pro 12-Core 2010/2012 memory kit

This 24GB kit contains six 4GB DDR3 1333 ECC registered DIMMs built for the Mac Pro 12-Core models from 2010 and 2012. It matches the Apple order number MD771LL/A and model identifier MacPro5,1. The modules run at 1.50V and use major-brand chips validated for those systems.

Replaces smaller DDR3 ECC kits

The kit upgrades a Mac Pro 12-Core that shipped with less memory or that has older DDR3 modules installed. The jump is worth it when the workload needs more than the current capacity allows, such as virtualisation, large media projects or heavy multitasking on the supported Xeon 2.4GHz, 2.66GHz, 2.93GHz or 3.06GHz processors.

Verify Mac Pro model and slot count

Confirm the machine is a Mac Pro 12-Core from Mid 2010 or Mid 2012 with model ID MacPro5,1 and order number MD771LL/A. Ensure all six 240-pin slots are free or that you are replacing the full set, because this kit fills every slot. The system must accept DDR3 1333 ECC registered memory at 1.50V.

Perguntas sobre este artigo

Will these 240-pin RDIMM modules fit the Mac Pro 5,1 memory slots?

Yes, the 6 modules are 240-pin DDR3 RDIMMs built for the Mac Pro 5,1 (Mid 2010/2012, 12-Core) memory tray.

Do I need to install the six 4GB sticks in matched triplets for the 12-core Xeon memory controller?

Populate all six slots — three per processor — with identical 2Rx4 modules so each Xeon sees a matched three-channel set.

If a module fails years from now, can I replace just one 4GB stick or must I swap the full 24GB kit?

Each 4GB module carries a lifetime warranty, so a single stick can be exchanged without returning the whole kit.
