Mac Pro 12-Core Memory Kit

This 48GB kit contains six 8GB DDR3 1333MHz registered ECC modules built for the Apple Mac Pro 12-Core models from 2010 and 2012. It targets owners of MacPro5,1 systems who need the full 48GB capacity across all six slots. Buyers with 4-core or 8-core Mac Pros, or any non-Apple workstation, cannot use this memory.

Registered ECC RDIMM Build

Each module is a 240-pin RDIMM running at 1.50V with major-brand chips and a 2Rx4 rank configuration. The registered buffer and ECC circuitry provide the signal integrity and error correction that the Mac Pro memory controller requires for stable operation. Systems that accept only unbuffered non-ECC UDIMMs will not post with these modules installed.

48GB DDR3 1333MHz Capacity

The kit delivers 48GB at DDR3 1333 (PC3-10600) speed, matching the maximum supported frequency for the listed Xeon E5645, X5650, X5670 and X5675 processors. This capacity and speed combination is the deciding factor for Mac Pro 12-Core owners who want the highest supported memory configuration without exceeding the platform limits.

Perguntas sobre este artigo

Does the DDR3 1333 PC3-10600 rating set the maximum data rate for this kit?

The kit runs at DDR3 1333 MHz, which is the PC3-10600 speed grade. All six modules operate at that clock.

What physical slot and module count does the 6 x 8 GB configuration require?

The Mac Pro 2010 and 2012 12-core models have four memory risers with four slots each. This 240-pin RDIMM kit fills six of those slots.

What installation step is most often missed when seating these registered DIMMs?

Align the notch on the 240-pin module with the slot key, press straight down until both side clips snap shut, then verify the system recognises all 48 GB at startup.
