Capacity and Compatibility

This 192GB kit supplies twelve 16GB DDR4 2933 RDIMM modules built for the 2019 Mac Pro tower and rack models. It supports the 12, 16, 24 and 28-core Xeon configurations identified as MacPro7,1.

Speed and Registered Operation

The modules run at 2933 MHz PC4-23400 with a 1.20V supply and registered ECC buffering. Registered DIMMs add a clock cycle of latency and require a memory controller that supports registered operation, so they cannot be used in standard desktop boards.

Build and Daily Use

Major-brand chips are tested to stringent quality standards before shipping. The 288-pin RDIMM form factor matches the Mac Pro memory slots exactly, allowing a straightforward installation without adapters or tools.
