NEMIX RAM 576GB 6x96GB DDR5 4800 CL40 1.1V ECC Registered RDIMM memory upgrade for Supermicro H13SSF

576GB DDR5-4800 ECC RDIMM kit for Supermicro H13SSF

This six-module kit delivers 576GB of DDR5-4800 registered ECC memory in a 288-pin RDIMM form factor. Each 96GB module operates at 1.1V with CL40 timing and a 2Rx4 rank structure. It is built for the Supermicro H13SSF motherboard where full-capacity recognition and rated-speed operation depend on exact rank, voltage and timing alignment.

Registered DDR5 bandwidth and population limits

The DDR5-4800 interface provides a PC5-38400 data rate that the memory controller must sustain across all populated slots. Registered buffering reduces electrical load on the controller so every slot can be filled, but the board's own population rules still dictate which slots may be used together and in what order. Exceeding the motherboard's qualified configuration will prevent the system from posting at the rated speed.

576GB capacity headroom for multi-tenant workloads

Six 96GB modules give 576GB total addressable space, enough for dense virtualisation, in-memory databases or large container fleets running simultaneously. ECC corrects single-bit errors on the fly to avoid silent data corruption during sustained compute. The practical ceiling is the motherboard's maximum supported capacity per slot and per channel; once that limit is reached no further modules can be added.
