Mac Pro 2019 8-Core memory kit

This 256GB kit contains eight 32GB DDR4 2666 LRDIMM modules built for the Apple Mac Pro 2019 8-Core tower and rack models. It targets professionals who need the maximum factory-supported memory configuration for Xeon workstation workloads.

Capacity and headroom for Xeon tasks

The 256GB total capacity (8 x 32GB) provides ample headroom for large datasets, virtual machines and multi-application workflows on the 3.5GHz Xeon W-3223. ECC load-reduced operation maintains data integrity under sustained load, while the 2666/2667 MHz speed matches the system memory controller specification.

Build quality and daily implications

Modules use major-brand chips on a 288-pin LRDIMM PCB and run at 1.20V, matching the Mac Pro memory slot electrical requirements. The registered load-reduced design reduces electrical load on the memory bus, allowing all eight slots to be populated without signal degradation.
