Mac Pro 2019 24/28-Core Memory Kit

This 512GB kit supplies four 128GB DDR4 2933 LRDIMM modules built specifically for the Apple Mac Pro 2019 with 24-core or 28-core Xeon processors. It targets professionals who need maximum memory capacity for rendering, virtualization or large dataset workloads on these workstations. The modules are validated for MacPro7,1 systems including both tower and rack configurations. ECC load-reduced operation protects data integrity during extended compute tasks.

Four-Module LRDIMM Upgrade

Each 288-pin module installs directly into the Mac Pro memory slots without adapters or additional hardware. The load-reduced design reduces electrical load on the memory controller, allowing all four slots to be populated at the rated 2933MHz speed. Operating at 1.20V, the kit draws standard DDR4 power while freeing the builder from mixing module capacities or speeds. No firmware changes or special tools are required for installation.

512GB Capacity Headroom

The 512GB total capacity comfortably handles multi-VM environments, 8K video timelines and in-memory databases that would exceed smaller configurations. Workloads requiring more than 512GB or faster memory speeds will hit the architectural limit of this platform. Buyers needing higher bandwidth or greater density must move to a newer workstation generation, as the Mac Pro 2019 memory controller caps at DDR4 2933 with LRDIMM topology.

이 상품에 대한 질문

Will the 2933 MHz DDR4 LRDIMM speed be maintained under sustained heavy workloads on the 28-core Xeon W-3275M?

The modules run at DDR4 2933 (PC4-23400) with a 1.20 V operating voltage; ECC load-reduced design helps maintain signal integrity during continuous high-throughput tasks on the 28-core processor.

How much heat and power do the four 128 GB LRDIMMs generate when the Mac Pro 2019 runs all day?

Each module operates at 1.20 V; the load-reduced architecture reduces electrical loading on the memory bus, which helps limit heat output and power draw during extended operation.

Which Mac Pro 2019 configurations must I already own for this 512 GB kit to work?

The kit is validated for MacPro7,1 models A2304 (EMC 3413) and A1991 (EMC 3203) equipped with the 2.5 GHz Xeon W-3275M or 2.7 GHz Xeon W-3265M 24-core or 28-core processors.
