System-Specific 512GB DDR4 Kit

This NEMIX RAM kit delivers 512GB across eight 64GB DDR4 2933MHz ECC RDIMM modules built for the Apple Mac Pro 2019 7,1. Registered buffering and CL21 timing operate at 1.2V to match the workstation's memory architecture.

Suited for maximum-capacity Mac Pro upgrades

Editors, researchers and virtualisation hosts who need the full 512GB ceiling supported by the 2019 Mac Pro will use every slot. Buyers whose projects stay below that ceiling or who do not require ECC registered memory should consider smaller or unbuffered kits.

ECC RDIMM registered architecture

The decisive specification is the 288-pin ECC registered RDIMM design with 2Rx4 organisation; only modules with this exact buffering and error-correction profile are compatible with the Mac Pro 2019 memory controller.

Questions about this item

How much power does the 1.2 V DDR4 2933 RDIMM kit draw under sustained load?

Each module operates at 1.20 V, the standard DDR4 voltage; total system draw depends on the Mac Pro 2019 memory controller and workload.

What must the Mac Pro 2019 already have for this 8×64 GB kit to be recognised?

The workstation must run macOS or firmware that supports 288-pin DDR4 2933 MHz ECC registered RDIMMs and provide eight free memory slots.

Will the CL21 registered ECC modules work alongside any original Apple memory left in the system?

Apple specifies DDR4 2933 MHz ECC RDIMMs for the Mac Pro 7,1; mixing ranks or latencies is not validated by Apple and may prevent boot.
