192GB ECC RDIMM kit for 2019 Mac Pro

This 192GB kit contains six 32GB DDR4 2933 registered ECC modules built for the Mac Pro 7,1 tower and rack models. It targets professionals running 12, 16, 24 or 28-core Xeon W processors who need maximum memory capacity for large datasets or virtual machines.

Registered ECC with major-brand chips

The modules use major-brand chipsets in a 2Rx4 registered ECC layout, delivering error correction and signal buffering that the Mac Pro memory controller requires. This configuration lets all twelve DIMM slots operate at the specified 2933 MT/s without the stability issues seen with unbuffered alternatives.

288-pin RDIMM form factor for Mac Pro slots

Each stick follows the standard 288-pin RDIMM pin-out, so it seats directly in the Mac Pro’s user-accessible DIMM bays without adapters. The 1.20V operating voltage matches the platform specification. Builders needing more than 192GB or wanting non-ECC memory should look elsewhere.

Questions about this item

Will the six 32 GB RDIMM modules need any replacement or maintenance after installation?

The modules are solid-state with no moving parts, so no routine maintenance is required; they are covered by a lifetime warranty if a defect ever appears.

What limit appears first when the 2933 MHz ECC RDIMMs run sustained workloads in the Mac Pro?

The system memory controller caps bandwidth at the DDR4 2933 specification, so throughput ceiling is reached before thermal or power limits.

How much heat and power do the 1.2 V registered DIMMs produce during all-day operation?

Each module runs at 1.20 V DDR4 standard voltage; registered buffering adds minimal overhead, so total heat stays within the Mac Pro's cooling design.
