Mac Pro 2019 memory kit

This 48 GB kit contains six 8 GB DDR4 2933 RDIMM modules built for the Mac Pro 2019 in 12 16 24 and 28 core configurations. It is intended for professionals who need ECC registered memory to expand their workstation capacity.

Installation and capacity fit

The modules use the 288 pin RDIMM form factor and operate at 1.20 V. They install directly into the Mac Pro memory slots and are validated for Apple model IDs MacPro7 1 and order numbers BTO CTO. The six module population fills the available channels for the supported Xeon processors.

Sustained workload behaviour

ECC registered operation detects and corrects single bit errors during long rendering or compute sessions. The DDR4 2933 speed maintains consistent throughput under continuous load without the voltage increase that higher frequency kits require.

Questions about this item

Will the 2933 MHz speed and ECC registered design stay stable when all six slots are populated under continuous load?

The kit runs at DDR4 2933 (PC4-23400) with ECC registered modules, which the Mac Pro 2019 memory controller supports across all twelve slots, so a full six-module set operates at the rated speed without down-clocking.

How much heat and power does the 1.20 V RDIMM kit add when the Mac Pro runs 24/7?

Each 8 GB module draws 1.20 V standard DDR4 voltage; registered DIMMs spread the electrical load across the memory controller, keeping thermals within the Mac Pro's existing cooling design for sustained workloads.

Which Mac Pro 2019 model identifiers must I already own for this 48 GB kit to be recognised?

The memory is validated for MacPro7,1 systems with order numbers A2304 (EMC 3413) or A1991 (EMC 3203) and the 12, 16, 24 or 28-core Xeon W processors listed in the compatibility table.
