Mac Pro 2019 ECC RDIMM kit

This 96 GB kit contains six 16 GB DDR4 2933 MHz registered ECC modules built for the 2019 Mac Pro tower and rack models. It uses major-brand chips at 1.20 V and carries the MacPro7,1 identifier for direct compatibility.

Suits 12- to 28-core Xeon workstations

Ideal for editors, developers and scientists who need maximum supported memory in a 2019 Mac Pro. Not suited for earlier Mac Pro models, non-ECC platforms, or systems that require unbuffered DIMMs.

Six slots filled with 16 GB each

The 96 GB total fills every slot on 12-core, 16-core, 24-core and 28-core configurations. Headroom is fixed at the platform maximum; larger capacities are not supported by this hardware.

Questions about this item

Will this 96GB kit of six 16GB DDR4 2933MHz ECC RDIMMs work in my Mac Pro 7,1 with the 2.5GHz Xeon W-3275M processor?

Yes, the kit is validated for MacPro7,1 and the listed Xeon W-3275M, W-3265M, W-3245 and W-3235 CPUs across 12, 16, 24 and 28-core models.

Can I add this 6x16GB RDIMM kit to the existing 8x8GB modules already in my 2019 Mac Pro tower?

The Mac Pro 2019 has 12 DIMM slots; filling all 12 with matched 16GB RDIMMs is supported, but Apple recommends identical capacity per channel for optimal performance.

How do I confirm the full 96GB is recognised at DDR4 2933MHz with ECC active after installation?

Open System Report > Memory — you should see six 16GB DDR4 2933 ECC RDIMM entries, total 96GB, with ECC status shown as Enabled.
