Built for Mac Pro 2019

This 768GB kit contains twelve 64GB DDR4 2933 ECC registered DIMMs designed for the Mac Pro 2019 in 12, 16, 24 and 28-core tower and rack configurations. It matches the MacPro7,1 identifier and Apple order numbers A2304 and A1991.

288-pin DDR4 2933 registered ECC

The decisive specification is the registered ECC DDR4 2933 288-pin form factor required by the Mac Pro 2019 memory controller. Unbuffered or non-ECC modules will not work in this system.

768GB maximum capacity

Twelve slots filled with 64GB modules reach the 768GB ceiling supported by the 2019 Mac Pro. Workloads needing more memory than this cannot be accommodated on this platform.

Perguntas sobre este artigo

How does the 2933 MHz speed translate to real bandwidth inside the Mac Pro 2019?

The modules operate at the rated DDR4 2933 MHz frequency, providing PC4-23400 data rates when installed in compatible Mac Pro 2019 systems with supported Xeon processors.

What does the ECC Registered RDIMM specification mean for error handling in this Mac Pro?

The ECC Registered design detects and corrects single-bit memory errors and adds a register to buffer address and command signals, improving data integrity and signal stability under heavy workloads.

Will the 12 modules fit the memory slots of the 2019 Mac Pro tower and rack models?

The 288-pin RDIMM form factor matches the DIMM slots on both the Mac Pro Tower and Mac Pro Rack (MacPro7,1), allowing all 12 modules to be installed directly.
