Micron Technology, Inc. server RAM

What this module is

Micron MTC40F2047S1RC64BB1R is a 128GB DDR5-6400 ECC RDIMM built for server platforms that require registered error-correcting memory. It adds a single high-capacity DIMM to compatible multi-socket systems.

Who this suits and who it does not

This module fits administrators who need maximum per-slot density for virtualisation, in-memory databases or large-container deployments. Buyers whose boards only accept unbuffered UDIMMs, who need lower-capacity sticks to populate many channels, or who require speeds other than 6400 MT/s should look at other parts.

Deciding specification

The 128GB capacity per DIMM is the single figure that determines whether this part solves the density requirement; verify the platform’s maximum supported capacity per slot and qualified vendor list before purchasing.
