System-specific server memory kit

This 768GB kit contains twelve 64GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1V operation. Registered ECC design with 2Rx4 organisation targets enterprise workloads on the Supermicro H14SSL-NT motherboard.

Verify motherboard population rules

Consult the H14SSL-NT manual for approved DIMM population order and maximum supported capacity per channel before ordering. The 288-pin registered form factor is required; unbuffered or SODIMM modules will not fit or function.

Thermals noise and power draw

Modules run at the standard 1.1V DDR5 voltage without integrated heat spreaders, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller during full-population operation.
