NEMIX RAM DDR5 4800 64GB (2x32GB) ECC RDIMM CL40 1.1V Supermicro H13SVW-NT memory upgrade

Server-grade DDR5 64GB kit

This 64GB kit contains two 32GB DDR5 4800 Registered ECC RDIMMs built for the Supermicro H13SVW-NT motherboard. The 2Rx8 modules run at 1.10V with CL40 timing and match the exact rank, voltage and timing the board's memory controller expects. System integrators upgrading compatible Supermicro platforms receive a verified fit that populates every slot at rated speed. Buyers needing unbuffered UDIMMs or laptop SODIMMs cannot use these modules.

Sustained-load stability

Registered architecture buffers the command and address signals so the memory controller stays within its electrical limits even when all channels are fully populated. ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The 1.10V operating voltage keeps power draw predictable under continuous server workloads. Workloads that demand higher frequencies or lower latencies than DDR5 4800 CL40 will not be satisfied by this kit.

DDR5 4800 interface limits

The PC5-38400 standard caps transfer rate at 4800 MT/s, so bandwidth scales with channel count rather than per-module speed. Four 288-pin RDIMM slots on the target board set the physical ceiling for this kit's capacity. Mixing ranks or voltages beyond the board's qualified vendor list breaks the memory-training sequence at boot. Systems requiring speeds above 4800 MT/s or capacities beyond the motherboard's validated maximum must choose a different memory specification.
