16GB DDR4 ECC RDIMM kit for 2019 Mac Pro

This 16GB kit contains two 8GB DDR4 2933MHz registered ECC modules built for the 2019 Apple Mac Pro tower and rack models. It uses 288-pin RDIMM form factor and runs at 1.20V with major-brand chips. The memory is designed for MacPro7,1 systems with 12, 16, 24 or 28-core Xeon W processors.

Suits owners upgrading a 2019 Mac Pro.

The modules are validated for Apple model IDs MacPro7,1 and order numbers A2304, A1991 with EMC 3413 and 3203. They will not fit earlier Mac Pro generations, iMac Pro, Mac Studio or any non-Apple workstation. Builders needing different capacities, speeds or unbuffered DIMMs should look elsewhere.

Registered ECC RDIMM requirement decides fit

The 2019 Mac Pro requires registered ECC DDR4 RDIMMs; this kit meets that exact specification with 1Rx8 organisation. Using unbuffered, non-ECC or different pin-count memory will prevent the system from booting. Confirm your Mac Pro is a 2019 tower or rack model before ordering.
