Mac Pro 2019 Memory Upgrade

This 64GB kit contains eight 8GB DDR4 2933 ECC RDIMM modules built for the 2019 Mac Pro in 12, 16, 24 and 28-core configurations. It targets professionals who need the full 12-slot capacity populated with registered, error-correcting memory for Xeon workstations.

Registered DIMM Build and 288-Pin Fit

Each module uses a registered buffer and 288-pin RDIMM form factor that seats directly into the Mac Pro memory slots. The registered design adds one clock cycle of latency but allows the memory controller to drive all eight modules reliably at the rated 1.20V without signal degradation.

DDR4 2933 Bandwidth Ceiling

The PC4-23400 rating sets a hard ceiling on throughput; workloads that scale beyond this bandwidth will not gain from faster modules because the platform locks the memory controller to 2933 MT/s. Buyers needing higher memory bandwidth must move to a different platform.

Questions about this item

What DDR4 speed does this 2933 MHz kit run at in a 2019 Mac Pro?

The modules operate at DDR4 2933 MHz (PC4-23400) as standard in the supported Mac Pro models.

Does the 288-pin RDIMM form factor fit the Mac Pro (2019) memory slots?

Yes, the 288-pin RDIMM design matches the Mac Pro (2019) DIMM slots for direct installation.

How are the eight 8 GB modules installed, and what step is often missed?

Install all eight modules to fill every slot; the common mistake is leaving slots empty, which reduces memory bandwidth.
