384GB DDR4 ECC RDIMM kit for Mac Pro 2019

This 384GB kit contains six 64GB DDR4 2933MHz ECC registered DIMMs built for the Apple Mac Pro 7,1 2019. Modules run at 1.2V with CL21 latency and use major OEM chips from Samsung, Micron or Hynix. The registered design adds stability for workstation workloads.

Registered ECC modules with 2Rx4 organisation

Each module is a 288-pin DDR4 RDIMM with 2Rx4 rank configuration and on-die ECC. Registered buffering reduces electrical load on the memory controller, allowing all six slots to be populated at the rated 2933MHz speed. No heat spreaders are fitted, matching the factory Mac Pro airflow design.

Suits Mac Pro 2019 owners needing maximum 384GB

This kit fills all six DIMM slots for users running virtualisation, large datasets or video timelines that benefit from 384GB of ECC memory. Buyers who need a smaller upgrade or non-ECC modules for a different platform should look elsewhere.

Questions about this item

Do the 64 GB RDIMM modules need any periodic maintenance or component replacement after installation?

No, the modules are solid-state with no moving parts and require no scheduled maintenance or component replacement once installed in the Mac Pro 2019.

What is the first limit reached when the 384 GB kit runs sustained workloads at 2933 MHz?

The CAS latency of CL21 at 1.20 V sets the timing boundary that the memory controller observes continuously during sustained operation.

How much heat and power do the six 2Rx4 modules produce when the system runs all day?

Each module operates at 1.20 V without a heat spreader; total power draw scales with the 384 GB capacity but stays within standard DDR4 RDIMM thermal limits for the Mac Pro 2019 chassis.
