Mac Pro 2019 memory kit

This 128GB kit contains two 64GB DDR4 2933 ECC LRDIMM modules built for the 2019 Mac Pro in 12, 16, 24 and 28 core configurations, both tower and rack models. It targets professionals who need Apple certified memory for MacPro7,1 systems using Xeon W-3235, W-3245, W-3265 or W-3275M processors.

128GB headroom for heavy workloads

The dual module kit delivers 128GB total capacity at 2933MHz PC4-23400 speed with 1.20V operation. Load reduced ECC architecture supports demanding multi-tasking and large dataset handling, while the two module layout leaves six slots free for future expansion within the twelve slot limit of the platform.

288-pin LRDIMM build quality

Each module uses major brand chips on a 288-pin load reduced DIMM form factor validated for Apple Mac systems. The registered ECC design improves signal integrity across full memory populations, and the Mac certified compatibility covers model IDs MacPro7,1 with order numbers A1991 EMC 3203 and A2304 EMC 3413.

Questions about this item

Will the 2933 MHz ECC LRDIMM modules work with the existing 2933 MHz ECC LRDIMM sticks in my Mac Pro 2019?

Yes, matching the 2933 MHz DDR4 ECC LRDIMM specification and 1.20V voltage allows them to run together when installed in the correct DIMM slots.

How can I confirm the 128GB kit (2x64GB) is recognised at 2933 MHz after installation?

Open About This Mac or System Report; the Memory tab should show 128 GB total, two 64 GB modules, DDR4 LRDIMM, ECC enabled and a speed of 2933 MHz.

What comes in the box and what must I buy separately?

The box contains the 128 GB kit (two 64 GB DDR4 2933 MHz ECC LRDIMM modules). No extra parts or tools are required for installation in a compatible Mac Pro 2019.
