Purpose-built Mac Pro memory kit

This 96GB kit contains twelve 8GB DDR4 2666 ECC registered DIMMs built for the 2019 Mac Pro tower and rack models. The modules run at 1.20V and carry the Apple model IDs MacPro7,1 and order numbers A2304 (EMC 3413) and A1991 (EMC 3203). They are validated for the 3.5GHz Xeon W-3223 8-core processor.

Who should buy and who should not

Creative professionals and developers who need the full 12-slot capacity for large datasets, virtual machines or 8K timelines will use every module. Buyers whose Mac Pro has fewer than twelve free slots, or who only need a modest capacity increase, should look at a smaller kit instead.

The specification that decides fit

The kit uses 288-pin DDR4 RDIMMs with ECC registered operation at 2666/2667 MHz (PC4-21300). If your 2019 Mac Pro requires registered ECC modules at this speed and pin count, the memory will install and run; if the system expects unbuffered or non-ECC DIMMs, it will not work.
