16GB DDR4 2666 ECC VLP UDIMM for Supermicro

This 16GB DDR4 2666 CL19 2Rx8 VLP ECC UDIMM is built for Supermicro SuperServer 5019S series systems. It runs at 1.2V on a 288-pin interface and carries JEDEC and ROHS compliance for a warranty-safe upgrade.

Who this fits and who it does not

It suits administrators expanding a 5019S-L, 5019S-M, 5019S-M2, 5019S-ML or 5019S-MN4 with a single low-profile module. It is not for builds that need registered DIMMs, non-ECC memory, higher speeds than 2666, or capacities beyond 16GB per slot.

The deciding specification

The module is a 288-pin DDR4 2666 PC4-21300 CL19 2Rx8 VLP ECC Unbuffered DIMM at 1.2V; if the server requires registered memory, a different voltage, or a taller profile, this part will not work.

Highlights

  • 16 GB DDR4 2666 CL19 boosts server responsiveness
