192GB DDR4 ECC LRDIMM Kit

This 192GB kit contains six 32GB DDR4 2666 ECC Load-Reduced DIMMs built for the Apple Mac Pro 2019 8-Core tower and rack models. It targets professionals who need maximum memory capacity for virtualization, large datasets or heavy creative workloads on these specific workstations.

Verify Mac Pro Model and Slot Count

Confirm your system is a MacPro7,1 with model numbers A2304 or A1991 and that all twelve DIMM slots are free or can accommodate six modules. The memory runs at 1.20V and requires the Xeon W-3223 3.5GHz processor or compatible 2019 8-Core configuration for correct operation.

288-Pin LRDIMM Build and Daily Use

Each module uses a 288-pin LRDIMM form factor with major-brand chips and 2Rx4 organisation, reducing electrical load on the memory controller for stable operation at full capacity. The ECC Load-Reduced design corrects single-bit errors and helps maintain data integrity during extended rendering or compute sessions.

Perguntas sobre este artigo

Does the 192GB kit contain six 32GB modules or do I need to buy anything else?

The kit includes six 32GB LRDIMM modules for a total of 192GB; nothing else is required for installation.

Should I choose the 2666 MHz or 2667 MHz speed rating for my Mac Pro?

Both ratings refer to the same DDR4 2666/2667 MHz PC4-21300 specification; the modules run at the speed your Mac Pro supports.

What does the ECC Load Reduced label mean for my Mac Pro 2019 with the 3.5GHz Xeon W-3223?

ECC Load Reduced provides error correction and reduced electrical load on the memory controller, allowing the six-module 192GB configuration to run stably at 2666 MHz.
