NEMIX RAM DDR5 4800 ECC RDIMM 512GB 4x128GB CL40 1.1V Server memory upgrade

512GB DDR5-4800 ECC RDIMM kit

This 512GB kit contains four 128GB DDR5-4800 registered ECC modules built for the Supermicro H13SVW-NT-OS1 motherboard. Each DIMM runs at 1.1V with CL40 timing and a 2Rx4 rank layout that matches the board's memory-controller expectations. It is intended for administrators who need maximum supported capacity in a single validated package.

Registered ECC with 2Rx4 organisation

The registered buffer reduces electrical load on the memory controller so all four slots can be populated at full speed, while on-die ECC corrects single-bit errors before they affect running workloads. The 2Rx4 rank structure and 1.1V operating point are the exact values the platform firmware looks for during training, avoiding down-clocks or capacity limits caused by mismatched modules.

DDR5-4800 platform ceiling

DDR5-4800 is the baseline transfer rate for this generation; the modules will not exceed PC5-38400 bandwidth regardless of CPU capability. Population rules for the H13SVW-NT-OS1 may restrict which slots can be filled simultaneously or limit total capacity per channel, so the system manual must be consulted before installation. No heat spreader is fitted, so airflow across the bare PCBs must be provided by the chassis.
