16 GB DDR4 ECC RDIMM for Supermicro X11SD series

This 16 GB DDR4 2400 MHz registered ECC module targets servers, workstations and NAS systems built on Supermicro motherboards X11SDS-12C, X11SDS-14C, X11SDS-16C, X11SDS-8C and X11SDV-12C-TLN2F. It replaces Supermicro part numbers MEMDR416LCL06ER24, MEMDR416LHL03ER24 and MEMDR416LSV01ER24.

Registered ECC design changes compatibility

The registered ECC architecture provides error correction and signal buffering required by multi-socket server platforms. It will not work in standard desktop computers and cannot be mixed with unbuffered memory modules.

16 GB single-module capacity headroom

A single 16 GB RDIMM adds substantial memory to compatible Supermicro boards for virtualization, database or file-serving workloads. Systems needing more than 16 GB per slot or requiring unbuffered memory must choose a different module type.

Questions about this item

Will the ECC RDIMM modules need any firmware updates or periodic replacement once installed in a Supermicro X11SDV-12C-TLN2F?

No firmware updates are required for the DDR4 ECC RDIMM modules. They are designed to run continuously in server and workstation environments without scheduled replacement.

What thermal limit appears first when the 16 GB DDR4 2400 CL17 kit runs at full load all day?

The modules operate at 1.2 V without a heat spreader, so the DRAM junction temperature reaches its rated limit before any other component under sustained full-load operation.

How much power does the 288-pin 2Rx8 registered DIMM draw and how noisy is it during 24/7 operation?

The 1.2 V DDR4 RDIMM consumes only the power required by the memory controller and produces no audible noise because it has no moving parts or active cooling.
