384GB DDR4 2933 ECC LRDIMM Kit

This 384GB kit contains six 64GB DDR4 2933 ECC LRDIMM modules built for the Apple Mac Pro Rack 2020. It targets professionals who need maximum memory capacity for virtualization, rendering or large dataset workloads on that specific workstation.

DDR4 2933 Load-Reduced Limits

The DDR4 2933 interface caps transfer rates at PC4-23400 while the load-reduced architecture buffers signals to support the 4Rx4 density per module. This combination allows the high 384GB total but fixes latency at CL21 and voltage at 1.20V, so bandwidth and timing cannot be tuned beyond the standard.

4Rx4 Rank Configuration

Each 64GB module uses a 4Rx4 organisation that the Mac Pro Rack 2020 memory controller requires for full 384GB recognition. Populating all six slots with this rank layout is the single specification that determines whether the system will boot and address the complete capacity.

Questions about this item

Should I choose the 6 x 64 GB kit or a different capacity for my Mac Pro Rack 2020?

This kit provides 384 GB total across six 64 GB modules, filling all available slots for maximum memory capacity on the Mac Pro Rack 2020.

What does the 2933 MHz speed mean for actual performance in the Mac Pro Rack?

The modules run at DDR4 2933 (PC4-23400) with CL21 latency, delivering the rated throughput the Mac Pro Rack 2020 memory controller supports.

Does the 288-pin LRDIMM interface limit how much bandwidth I can use?

The 288-pin DDR4 LRDIMM form factor with load-reduced buffering is the required standard for this system; it operates at the platform's native 2933 MT/s data rate.
