Apple Mac Pro 12-Core Memory Kit

This 32GB kit contains eight 4GB DDR3 1333 ECC registered DIMMs built for the 12-core Mac Pro models released in 2010 and 2012. Each module runs at 1.50V and uses a 240-pin RDIMM form factor with major-brand chips. The kit matches Apple order number MD771LL/A and model ID MacPro5,1.

Suits owners of mid-2010 or mid-2012 12-core towers

The memory is validated for Xeon processors including the 2.4GHz E5645, 2.66GHz and 2.93GHz X5650 and X5670, and 3.06GHz X5675. It will not fit earlier Mac Pro models, later cylinder Mac Pro units, or any non-Apple workstation that requires unbuffered DIMMs or a different DDR generation.

Eight slots filled with 4GB modules

The 32GB total provides headroom for virtual machines, large media projects and multi-application workflows on supported 12-core systems. Capacity stops at 32GB because all eight DIMM slots are occupied; users needing more memory must replace modules rather than add to the kit.

Questions sur cet article

Will this 32GB kit with 1333MHz ECC RDIMM modules work in my Mac Pro 5,1 that currently has 2.66GHz Xeon X5650 processors?

Yes, the kit is listed as compatible with Mac Pro 5,1 and the 2.66GHz Xeon X5650 CPU.

Can I mix these 4GB DDR3 1333 ECC RDIMM modules with my existing 2GB or 1GB DDR3 ECC RDIMM modules in the same Mac Pro?

The Mac Pro 5,1 requires identical modules in each triple-channel set; mixing capacities or ranks can prevent boot or reduce performance.

How can I confirm the full 32GB is recognised and running at 1333MHz with ECC active after installation?

Open About This Mac and System Report; the Memory section should show 32GB total, 1333MHz speed, and ECC status as Enabled for each slot.
