NEMIX RAM 512GB 4x128GB DDR5 6400 CL52 ECC RDIMM Supermicro H13SVW-NT memory upgrade

Capacity and purpose

This 512GB kit contains four 128GB DDR5 registered ECC RDIMMs built for the Supermicro H13SVW-NT motherboard. It targets administrators who must fill every slot at the board's rated 6400 MT/s without manual tuning. Buyers needing non-ECC or unbuffered modules cannot use this kit.

Build integration

Each module uses the 288-pin RDIMM form factor with 2Rx4 organisation and 1.10V operation exactly as the H13SVW-NT memory controller expects. Registered buffering offloads the controller so all four slots run fully populated at the rated CL52 timing. The kit requires a motherboard that supports registered ECC DDR5 and the correct DIMM population order.

Thermals and power

Operating at 1.10V keeps per-module power low even with all four ranks active. No heat spreaders are fitted, so airflow across the bare PCB is required in dense chassis. The registered design reduces electrical load on the memory controller, helping system power stay predictable under sustained workloads.
