Mac Pro 2019 DDR4 ECC Upgrade

This 64GB kit contains four 16GB DDR4 2933MHz registered ECC RDIMMs built for the 2019 Mac Pro tower and rack models. It supports the 12-core, 16-core, 24-core and 28-core Xeon W processors listed by Apple. The modules run at 1.20V and use major-brand chips on a 288-pin form factor. Installation adds 64GB of certified memory to compatible MacPro7,1 systems.

Suited for MacPro7,1 owners adding ECC registered

The kit fits Mac Pro units with model IDs A2304 (EMC 3413) and A1991 (EMC 3203) running the specified Xeon W CPUs. Builders who need non-ECC UDIMMs, unregistered DIMMs, or a different pin count cannot use these modules. Systems requiring memory speeds other than DDR4 2933MHz or voltages other than 1.20V should look elsewhere.

Registered ECC RDIMM at DDR4 2933MHz

The decisive specification is the DDR4 2933MHz ECC registered RDIMM design on a 288-pin interface. Only Mac Pro 2019 models that accept this exact module type and speed will recognise the full 64GB capacity across the four slots.
