NEMIX RAM DDR5 256GB 8x32GB 4800MHz CL40 1.1V ECC Registered RDIMM memory upgrade

Server-grade DDR5 ECC RDIMM kit

This 256GB kit contains eight 32GB DDR5 4800MHz Registered DIMMs built for the Supermicro H13SSW motherboard. The modules run at 1.1V with CL40 latency and use a 2Rx8 organisation that matches the board's memory controller requirements. Registered buffering and on-die ECC protect data integrity in multi-socket server workloads. It is not suited for desktop boards that accept only unbuffered UDIMMs.

Thermals and power at rated speed

Operating at the standard 1.1V DDR5 voltage keeps power draw predictable across all eight slots when the system runs at 4800MHz. The modules have no heat spreader, so airflow through the server chassis manages module temperature during normal operation. Registered buffering reduces electrical load on the memory controller, helping overall platform stability. Noise and thermals remain governed by the server's own fan curves rather than the memory itself.

Behaviour under sustained load

Full population of all eight slots at 4800MHz is supported by the Registered architecture, allowing continuous throughput without down-clocking due to signal integrity limits. ECC corrects single-bit errors in real time, preventing silent data corruption during long compute jobs. The 2Rx8 rank structure maintains bandwidth consistency across extended sessions. Verify the motherboard manual for approved population order and maximum supported capacity before deployment.
