Mac Pro 2019 memory upgrade

This 256GB kit contains eight 32GB DDR4 2933 ECC RDIMM modules built for the 2019 Mac Pro tower and rack models. It supports the 12, 16, 24 and 28-core Xeon configurations listed by Apple.

ECC registered DDR4 2933 specification

Each module runs at 2933MHz PC4-23400 with 1.20V voltage and 2Rx4 rank organisation. The registered ECC design provides error correction and signal buffering required by the Mac Pro memory architecture.

Sustained workload behaviour

Registered ECC modules maintain data integrity during continuous multi-threaded tasks such as rendering, compilation or large dataset processing. The eight-module population fills all memory channels for maximum sustained bandwidth.

Questions about this item

What does the 256 GB capacity look like when all eight 32 GB modules are installed in a Mac Pro 2019?

The kit fills all eight slots with 32 GB RDIMMs, giving the full 256 GB of ECC registered memory supported by the MacPro7,1 platform.

How does the DDR4 2933 PC4-23400 rating translate to real-world throughput on this system?

The modules operate at 2933 MHz on the Mac Pro's memory controller, providing the bandwidth specified by the PC4-23400 standard for each channel.

What physical clearance and slot requirements do the 288-pin RDIMMs need in the Mac Pro tower or rack?

Each module is a standard 288-pin DDR4 RDIMM; the Mac Pro 2019 tower and rack both accept eight such modules in the user-accessible DIMM slots.
