NEMIX RAM DDR5-6400 192GB 12x16GB ECC RDIMM CL52 1.1V Supermicro H14DSG-O-CPU

192GB DDR5-6400 ECC RDIMM kit

This 192GB kit contains twelve 16GB DDR5-6400 modules built to PC5-51200 specification. Registered ECC architecture with 1Rx8 organisation and CL52 latency at 1.1V matches the memory controller requirements of the Supermicro H14DSG-O-CPU motherboard. It is intended for server administrators who need maximum verified capacity on this platform.

DDR5 RDIMM population constraints

DDR5 Registered DIMMs use a 288-pin interface that is mechanically incompatible with UDIMM or SODIMM slots. The registered buffer allows all twelve slots to be populated simultaneously at the rated 6400MT/s speed, but the motherboard manual dictates the exact population order and any per-channel limits. Buyers who need a different capacity or rank configuration cannot use this fixed 12×16GB kit.

Build and daily handling

Modules ship without heat spreaders, relying on chassis airflow for cooling in dense server configurations. The 288-pin RDIMM keying prevents accidental insertion into consumer boards, and the registered design keeps electrical loading low even with every slot filled. Technicians should follow the board’s documented installation sequence to avoid recognition errors during bring-up.
