Apple Mac Pro 2019 Memory Upgrade

This 64GB kit contains two 32GB DDR4 2933MHz ECC Registered RDIMM modules built for the 2019 Mac Pro tower and rack models. It matches the Apple MacPro7,1 platform and supports the 12, 16, 24 and 28-core Xeon configurations listed by Apple. The modules run at 1.20V and use major-brand chips qualified for Mac Pro 2019 order numbers A1991 and A2304.

Who This Suits And Who Should Look Elsewhere

Editors, engineers and developers running virtual machines, large 3D scenes or multi-camera timelines on a 2019 Mac Pro gain immediate headroom with this 64GB kit. Buyers who need more than 64GB of capacity or who are upgrading a different Mac model should look elsewhere because this kit is validated only for MacPro7,1 systems.

Deciding Specification: ECC Registered RDIMM

The defining specification is the ECC Registered RDIMM form factor required by the 2019 Mac Pro memory architecture. Standard unbuffered DDR4 DIMMs will not work in this system, so confirming the registered ECC design is the single check that decides whether this is the correct part.

Questions about this item

Does the DDR4 2933MHz PC4-23400 ECC RDIMM run at its rated speed in the Mac Pro 2019?

Yes, the 2933 MHz modules operate at their full PC4-23400 rate when installed in compatible Mac Pro 2019 models with supported Xeon processors.

What physical space and slot type do the 288-pin RDIMMs require inside the Mac Pro 2019?

The kit uses standard 288-pin DDR4 RDIMM form factor and fits the Mac Pro 2019 memory bays designed for registered ECC modules.

How are the two 32GB modules installed, and what configuration step is often missed?

Install both modules in the recommended slots for 12, 16, 24 or 28-core Xeon CPUs; the common mistake is populating only one module or using mismatched slots, which prevents quad-channel operation.
