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.

Questions sur cet article

Will the 256GB DDR4 2666 LRDIMM kit work with the existing 3.5GHz Xeon W-3223 in my Mac Pro 7,1?

Yes, this kit is validated for the 3.5GHz Xeon W-3223 in MacPro7,1. The eight 32GB LRDIMM modules run at 1.20V and provide ECC load-reduced operation across all 256GB.

How can I confirm the 2666MHz ECC LRDIMM modules are recognised correctly after installation?

Open System Report in macOS and check Memory. You should see eight 32GB DDR4 2667MHz slots populated, showing ECC enabled and a total of 256GB.

Does the 8x32GB kit include the 288-pin LRDIMM modules only, or are tools and risers supplied?

The package contains the eight 32GB DDR4 2666 LRDIMM modules only. Mac Pro memory risers and any installation tools are not included.
