A-Tech 384GB Kit (6x64GB) DDR4 2933 ECC LRDIMM memory upgrade for Apple Mac Pro 2019

384GB DDR4 ECC LRDIMM kit for Mac Pro 2019

This 384GB kit contains six 64GB DDR4 2933MHz ECC Load Reduced DIMMs built specifically for the 2019 Mac Pro tower and rack models. It targets professionals running memory-intensive workloads on 12, 16, 24 or 28-core Xeon W processors who need the maximum supported capacity per slot. Buyers whose Mac Pro uses standard RDIMMs or requires a different speed grade cannot use this kit.

Sustained load behaviour with ECC LRDIMM topology

The Load Reduced design places a buffer on each module to reduce electrical load on the memory controller, allowing all six slots to operate at the rated 2933MHz speed under continuous heavy throughput. ECC circuitry detects and corrects single-bit errors in real time, preventing silent data corruption during long render, simulation or virtualisation sessions. The 1.20V operating voltage keeps power draw predictable across extended duty cycles.

288-pin LRDIMM form factor and Mac Pro slot layout

Each module uses the 288-pin LRDIMM form factor keyed for the Mac Pro's dedicated memory slots, ensuring correct alignment without adapters. Major-brand DRAM chips are used throughout the kit to maintain consistent timing across all six sticks. The Mac Pro 2019 architecture requires LRDIMMs for capacities above 32GB per slot, so standard unbuffered or registered DIMMs will not function in this configuration.
