Capacity and compatibility

This 384GB kit contains twelve 32GB DDR4 2933 ECC registered DIMMs built for the 2019 Mac Pro in 12, 16, 24 and 28-core configurations, both tower and rack models. The modules run at 1.20V and use major-brand chips on a 288-pin RDIMM form factor. They match Apple model IDs MacPro7,1 and order numbers A2304 (EMC 3413) and A1991 (EMC 3203).

Upgrade path and use case

The kit replaces the factory-installed memory in Xeon W-3275M, W-3265M, W-3245 and W-3235 systems when workloads exceed the original capacity. The jump is worthwhile for video editing, 3D rendering, scientific computing or virtualisation tasks that regularly saturate lower memory configurations and cause paging to storage.

Sustained-load behaviour

Registered ECC operation corrects single-bit errors and detects multi-bit errors during continuous operation, protecting data integrity in long render jobs or compute clusters. The DDR4 2933 speed maintains consistent bandwidth across all twelve slots without downclocking, so throughput scales linearly with the populated channels under heavy, sustained memory pressure.

Vragen over dit artikel

Does the 12-module 384GB kit fill all 12 DIMM slots in the Mac Pro 2019 tower and rack?

Yes, the kit contains 12 x 32GB RDIMMs that occupy every one of the 12 DDR4 slots in the Mac Pro 2019 (MacPro7,1) tower and rack models.

What is the correct installation sequence for the 12 x 32GB RDIMMs in the Mac Pro 2019 memory risers?

Populate the six slots on the upper riser first, then the six on the lower riser, following Apple's DIMM population order shown inside the access door.

Will the ECC registered RDIMMs require any firmware updates or periodic re-seating after installation?

No firmware update is needed; the modules run at 1.20V DDR4 2933 and are designed for continuous operation without re-seating.
