Mac Pro 12-Core 2010/2012 memory kit

This 64GB kit contains eight 8GB DDR3 1333 RDIMM modules built for the Apple Mac Pro 12-Core models from 2010 and 2012. It uses ECC registered chips at 1.50V and fits the 240-pin slots in those towers. The kit matches Apple order number MD771LL/A and model ID MacPro5,1.

DDR3 1333 registered ECC limits

DDR3 1333 (PC3-10600) registered ECC memory tops out at 1333 MHz on these platforms and cannot run faster without instability. The 240-pin RDIMM form factor is physically incompatible with UDIMM or SO-DIMM slots. Eight modules fill every slot on the 12-Core Mac Pro, leaving no room for further expansion.

2Rx4 rank configuration decides fit

Each 8GB module uses a 2Rx4 organisation that the Mac Pro 12-Core memory controller requires for full 64GB operation. Other rank layouts such as 1Rx4 or 2Rx8 will not be recognised at this capacity. Buyers needing a different rank structure must choose another kit.

Questions about this item

Should I pick the 8 x 8 GB kit or a different capacity for my Mac Pro?

This kit delivers 64 GB across eight 8 GB modules, filling all slots on the 12-Core Mac Pro (Mid 2010 or Mid 2012) for the maximum supported memory.

What does the 1333 MHz rating mean once the memory is installed in the Mac Pro?

The modules run at DDR3 1333 (PC3-10600), matching the native memory bus speed of the 2.4 GHz, 2.66 GHz, 2.93 GHz and 3.06 GHz Xeon processors listed for these systems.

Will the 240-pin RDIMM interface work in my Mac Pro and what does it cap?

Yes — the 240-pin ECC Registered RDIMM form factor is the exact type required by the Mac Pro 5,1 (A1289 EMC 2314-2 / 2629), and the DDR3 1333 bus caps the peak transfer rate at PC3-10600.
