Micron 32GB DDR4-2933 ECC RDIMM Server Memory

Part numbers and identification

Micron part numbers encode capacity, organisation and speed; the label on the module carries the full string. Buyers search for "MTA18ASF4G72PZ-2G9", "Micron 32GB 2933 RDIMM" and "PC4-2933Y Micron".

Specification

A single rank 32GB module uses Micron's higher density chips, which is what allows it to load the channel as lightly as a 16GB dual rank part and run two per channel at full speed.

Speed depends on the processor: 2933MT/s with second generation Xeon Scalable, 2666MT/s with first generation Gold and Platinum parts, and 2400MT/s with Silver 4100 parts. The capacity is the same at any speed, so the module is a safe purchase for a server that may have its processors upgraded later.

Twelve of these give a dual socket second generation server 384GB with one module per channel, and 24 give 768GB. For memory heavy virtualisation the 32GB step keeps the slot count manageable while leaving room to double later, which is why it is the most common capacity ServerDove supplies for this platform.

Installation

Shut down and unplug the server. Fit modules in the sequence printed on the system board, one per channel on each processor before doubling any channel, and seat each until the clips lock. Avoid mixing ranks within a channel where the existing modules are dual rank; put single rank modules together in their own channels if both types must coexist. Verify capacity and speed in the BIOS at first boot.
