16GB DDR5-6400 ECC RDIMM

This 16GB DDR5-6400 Registered ECC RDIMM is built for the Supermicro H14DSH motherboard. It runs at 1.1V with CL52 latency and a 1Rx8 organisation so the memory controller recognises it at full capacity and rated speed.

Replaces slower or unbuffered DIMMs

When a server is limited by lower-speed modules or non-registered memory, this kit lifts bandwidth to PC5-51200 while registered buffering offloads the controller for full-slot population. The jump is worth it when ECC error correction and maximum DIMM density are required for production stability.

Suits H14DSH builders needing registered ECC

Ideal for administrators upgrading or populating a Supermicro H14DSH with validated registered ECC memory. Not for systems that accept only UDIMM or SODIMM form factors, or for workloads that demand higher per-module capacities than 16GB.

Questions about this item

Will the 288-pin DDR5 RDIMM fit the DIMM slots on my Supermicro H14DSH motherboard?

Yes, the module uses the 288-pin RDIMM form factor that the H14DSH requires; it is not a UDIMM or SODIMM, so it seats correctly in the server's DDR5 slots.

What is the correct installation step that people often miss when adding this RDIMM to the H14DSH?

Follow the motherboard manual's DIMM population order for registered ECC modules so the memory controller recognises the 1Rx8 rank at full 6400 speed.

Does the lack of a heat spreader on this 1.10V DDR5 module mean I will need extra cooling later?

The module runs at the standard 1.10V DDR5 voltage without a spreader; adequate chassis airflow per the server specification keeps temperatures in range.
