Mac Pro 2019 384GB ECC RDIMM Kit

This 384GB kit contains six 64GB DDR4 2933MHz ECC registered DIMMs built for the 2019 Mac Pro tower and rack models. It uses major-brand chips at 1.20V and matches the MacPro7,1 platform requirements. The modules are 288-pin RDIMMs with a 2Rx4 rank configuration.

Suits Mac Pro 12/16/24/28-core owners

This memory fits Mac Pro systems with 12-core, 16-core, 24-core or 28-core Xeon W-3275M, W-3265M, W-3245 or W-3235 processors. It is not for users needing non-ECC unbuffered DIMMs, different capacities per module, speeds other than 2933MHz, or memory for earlier Mac Pro generations.

384GB capacity decides fit

The kit delivers exactly 384GB total capacity across six populated slots. Buyers whose workloads need more than 384GB must look at higher-density modules or larger kits. Buyers needing less memory should choose a smaller kit to avoid unused slots.

Questions about this item

Will these 288-pin RDIMMs fit the memory slots in a 2019 Mac Pro tower?

Yes, the 288-pin DDR4 RDIMM form factor matches the Mac Pro (2019) memory slots exactly.

What is the correct way to install the six 64 GB modules, and what step do people often miss?

Populate all six channels in the order shown in Apple's official guide; the common mistake is leaving a channel empty or mixing module sizes.

When should I expect to replace or service this 384 GB ECC registered kit?

ECC registered DDR4 modules have no scheduled maintenance; they are replaced only if a memory diagnostic reports a correctable or uncorrectable error.
