NEMIX RAM DDR5 32GB (2x16GB) 4800MHz ECC Registered RDIMM 1Rx8 CL40 1.1V Supermicro H13SSF memory upgrade

32GB DDR5 ECC RDIMM kit for Supermicro H13SSF

This 32GB kit contains two 16GB DDR5 4800MHz Registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H13SSF memory controller expects. The 1Rx8 organization and CL40 latency match the board's population rules so every slot is recognised at full capacity. It is designed for servers that require registered error-correcting memory and will not work in systems that only accept unbuffered UDIMMs or SODIMMs.

Thermals noise and power draw

Operating at 1.10V the modules draw minimal power and run without a heat spreader, relying on the server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping keep system power stable when all slots are populated. No active cooling is included so acoustics depend entirely on the host server's fan profile.

Build quality and daily implications

The 288-pin RDIMM form factor fits only motherboards wired for registered DDR5 memory; it cannot be installed in consumer boards or laptops. ECC circuitry corrects single-bit errors on the fly, preventing silent data corruption that could halt production workloads. Major OEM DRAM from Samsung Micron or Hynix underpins the lifetime replacement warranty and US-based technical support.
