Apple Mac Pro (2019) memory upgrade

This 128GB kit contains two 64GB DDR4 2933MHz ECC registered DIMMs built for the 2019 Mac Pro tower and rack models. It supports the 12-core, 16-core, 24-core and 28-core Xeon configurations identified as MacPro7,1. The modules run at 1.20V and use major-brand chips validated for Apple systems.

Check your Mac Pro model and slot layout

Verify that your machine is a 2019 Mac Pro (model IDs A2304 or A1991) with MacPro7,1 firmware before ordering. The kit provides two 288-pin RDIMMs, so ensure you have two free memory slots and that existing modules match the DDR4 2933MHz ECC registered specification for correct operation.

Sustained workload behaviour

The registered buffer and ECC circuitry maintain data integrity during extended rendering, virtualization or scientific compute sessions. Error correction prevents silent corruption over long runs, while the registered signal reduces electrical load on the memory controller when all slots are populated. Modules operate at the rated 2933MHz speed under continuous load.
