64GB DDR3 ECC Kit for Mac Pro

This 64GB kit contains eight 8GB DDR3 1333MHz ECC UDIMM modules designed for Apple Mac Pro systems. It targets owners of the Mid 2010 and Mid 2012 12-Core models who need maximum memory capacity for demanding workloads. The unbuffered ECC design provides error correction without registered signalling.

Check Mac Pro model and slot count

Verify your system is a Mac Pro 5,1 (A1289 EMC 2314-2 or 2629) with 12-Core Xeon processors such as the 2.4GHz E5645 or 3.06GHz X5675. Confirm all eight memory riser slots are free because this kit fills every available position. Ensure the firmware supports 64GB total capacity before ordering.

Fills all slots for maximum capacity

Installation occupies all eight DIMM slots on the dual-processor memory risers, leaving no room for further expansion. The 1.50V modules draw standard DDR3 power and rely on the Mac Pro's existing cooling airflow. This configuration frees the system from memory bottlenecks during heavy multitasking or virtualisation tasks.

Questions about this item

Does the 64GB kit contain eight 8GB modules or do I need to buy extra sticks?

The kit ships with eight 8GB DDR3 1333MHz ECC UDIMM modules, giving 64GB total, so no additional sticks are required.

Should I pick this 1333MHz ECC UDIMM kit or a different speed for my Mac Pro 5,1?

Apple specifies DDR3 1333MHz PC3-10600 ECC UDIMM for MacPro5,1; this kit matches that exact spec.

Will the 1333MHz rating actually run at that speed once installed in a Mac Pro 5,1?

The Mac Pro 5,1 memory controller operates DDR3 at 1333MHz, so the modules run at their rated 1333MHz speed.
