NEMIX RAM DDR5 ECC RDIMM 384GB (6×64GB) 4800 CL40 1.1V 2Rx4 Registered 288-pin Supermicro H13SVW-NT

384GB DDR5 ECC RDIMM kit for Supermicro H13SVW-NT

This 384GB kit contains six 64GB DDR5 Registered ECC modules built to the exact rank, voltage and timing the Supermicro H13SVW-NT memory controller expects. The 2Rx4 organization and 1.1V operation let every slot run fully populated at the rated DDR5-4800 speed without manual tuning. It is not suited for desktop boards that require unbuffered UDIMMs or for systems limited to lower maximum capacities per slot.

Thermals noise and power at DDR5-4800 1.1V

Operating at the standard 1.1V DDR5 voltage, the modules draw minimal power and generate little heat during normal server workloads. No heat spreaders are fitted, relying on chassis airflow to keep temperatures within specification. Registered buffering reduces electrical load on the memory controller, contributing to quieter, cooler operation compared with unbuffered alternatives at the same capacity.

Sustained load behaviour with Registered ECC

Under continuous heavy use the Registered architecture maintains signal integrity across all six slots, preventing the timing drift that can appear with unbuffered modules at full population. On-die ECC corrects single-bit errors in real time, stopping silent data corruption before it reaches applications. The CL40 latency remains stable throughout extended runs, delivering consistent throughput for virtualization, databases and compute clusters.
