NEMIX RAM 64GB DDR5 6400 2Rx4 CL52 1.1V ECC RDIMM Supermicro H13SSL-N memory upgrade

Exact-match DDR5 RDIMM upgrade

This 64GB DDR5-6400 (PC5-51200) module uses a 2Rx4 registered ECC design at 1.1V with CL52 timing. It fits the 288-pin RDIMM slots on the Supermicro H13SSL-N motherboard and is recognized at full capacity and rated speed without manual configuration. Builders who need a different form factor such as UDIMM or SODIMM cannot use this module.

Sustained enterprise workloads

Registered architecture offloads the memory controller so every populated slot runs at the full 6400 MT/s data rate under continuous load. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during long-running production tasks. The fixed 1.1V operating voltage keeps power draw stable across all ranks.

Thermal and power profile

No heat spreader is fitted, so airflow across the bare DRAM is required for normal server cooling. At 1.1V the module draws minimal power per DIMM while delivering 64GB capacity, and registered buffering reduces electrical load on the memory controller. Systems with restricted DIMM airflow or limited fan headers should verify thermal headroom before full population.
