Compatible Mac Pro 2019 Memory

This 768GB kit contains twelve 64GB DDR4 2933 ECC registered DIMMs built for the Apple Mac Pro 7,1. The modules run at 1.2V with CL21 timing and use a 288-pin RDIMM form factor. They are designed to meet the workstation's requirement for registered error-correcting memory.

Suits users maximising every slot

The kit fills all twelve memory slots, so it is aimed at professionals who need the full 768GB capacity for large datasets, virtualisation or rendering workloads. Buyers who only need a partial upgrade or who plan to mix capacities should look at smaller kits instead.

Registered ECC RDIMM requirement

The Mac Pro 2019 only accepts DDR4 2933 registered ECC RDIMMs; unbuffered or non-ECC modules will not work. This kit matches that exact specification with 2Rx4 organisation and 1.2V operation.

Questions about this item

Will the 2933 MT/s speed and CL21 latency hold steady when all 12 slots are populated on a Mac Pro 2019?

The kit runs at DDR4 2933 (PC4-23400) with CL21 timings at 1.2 V. Apple’s memory controller maintains the rated speed across all 12 DIMM slots when modules are matched.

How much heat does a full 768 GB kit produce and does it need active airflow?

Registered DDR4 RDIMMs at 1.2 V run cool; the bare modules have no heat spreader and rely on the Mac Pro’s internal fans for adequate cooling.

Does the Mac Pro 7,1 require a specific macOS version or firmware to recognise 64 GB RDIMMs?

The 2019 Mac Pro (MacPro7,1) supports 64 GB DDR4 ECC RDIMMs on its original firmware; no additional software is needed beyond a standard macOS install.
