384GB DDR5 ECC RDIMM Kit

This 384GB kit contains twelve 32GB DDR5-4800 registered ECC modules built to the exact rank, voltage and timing the Supermicro H14SSL-NT motherboard expects. It is designed for administrators who need maximum supported capacity in every slot without manual tuning. Buyers who need a smaller increment or non-ECC memory should look elsewhere.

Sustained Load Behaviour

Registered architecture offloads the memory controller so all twelve slots run fully populated at the rated 4800MT/s speed. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The CL40 latency and 1.1V operation remain stable across continuous server workloads.

Thermals, Noise and Power

Modules operate at the standard 1.1V DDR5 voltage with no heat spreaders attached. Power draw scales with the twelve-module population, while the registered design keeps electrical loading on the memory controller low. Cooling and airflow requirements follow the chassis and motherboard specifications.
