Exact-match DDR5-5600 ECC RDIMM for Supermicro

This 16 GB registered ECC module runs at DDR5 5600 (PC5-44800) with CL46 timing at 1.1 V. It is built as a 1Rx8 288-pin RDIMM so the motherboard recognises the full capacity and operates at the rated speed without manual tuning.

Sustained-load behaviour with registered ECC

Registered architecture buffers the command and address signals, allowing every slot to stay fully populated at the rated frequency during continuous workloads. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during long production runs.

Build and daily implications

The module uses major OEM chips from Samsung, Micron or Hynix and has no heat spreader, relying on server chassis airflow for cooling. The 288-pin RDIMM form factor fits only boards that require registered memory — it will not work in UDIMM or SODIMM slots, so verify your platform's population rules before installation.

Questions about this item

How much power does the 1.1V DDR5 5600 RDIMM draw under continuous load?

The module operates at 1.1V standard DDR5 voltage; actual draw depends on your server workload and the Supermicro H14SHM memory controller.

What motherboard slot and population rules must my Supermicro H14SHM already have free?

It needs one vacant 288-pin RDIMM slot and must follow the board's validated population order in the manual.

Will this 1Rx8 CL46 registered ECC DDR5 run at rated speed alongside slower DDR5 modules I keep installed?

The board will clock all populated slots to the lowest common speed and timing; mixing ranks or speeds can prevent full 5600 MT/s operation.
