NEMIX RAM DDR5 ECC RDIMM 16GB

This 16GB DDR5 ECC RDIMM operates at 4800MHz with CL40 latency and 1.1V voltage. The 1Rx8 registered module uses a 288-pin form factor built with major OEM chips. It is validated for the Supermicro H13SSF motherboard and delivers the exact rank, timing, and voltage the memory controller expects.

Who this suits and who should look elsewhere

System builders upgrading a Supermicro H13SSF server will find this module matches the board's registered DIMM requirement and population rules. Buyers needing unbuffered UDIMMs, SODIMM form factors, or capacities beyond 16GB per slot should verify their platform documentation before ordering.

Behaviour under sustained load

Registered architecture reduces electrical load on the memory controller, allowing stable operation when all slots are populated at rated speed. ECC corrects single-bit errors in real time, preventing silent data corruption during continuous workloads. The 1.1V operating voltage supports consistent thermal characteristics in dense server configurations.

Questions about this item

My Supermicro H13SSF motherboard — does it need registered ECC DDR5 RDIMMs like this 288-pin CL40 1.10V module to work?

Yes, the H13SSF requires 288-pin DDR5 RDIMMs with ECC and registered buffering; this 16 GB CL40 1.10V kit matches that exact specification.

Can I keep my existing DDR5 4800 RDIMMs and add this 1Rx8 16 GB module without slowing the memory controller?

The board will run all populated slots at the lowest common speed and latency; matching 4800 MHz CL40 1Rx8 modules keeps the controller at its rated 4800 MT/s.

After installing the module, how do I confirm the server sees the full 16 GB at 4800 MHz with ECC active?

Check the BIOS memory info or run dmidecode — it should report 16 GB, 4800 MT/s, PC5-38400, registered ECC, 1Rx8, 1.10 V.
