NEMIX RAM DDR5 4800 ECC RDIMM 384GB (6x64GB) CL40 1.1V 2Rx4 288-pin memory upgrade for Supermicro H14SSF

Exact-fit DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 384GB of DDR5-4800 registered ECC memory in six 64GB modules. It is built for administrators who need the precise rank, voltage and timing the Supermicro H14SSF memory controller expects. The 288-pin RDIMM form factor matches the board's physical slots and population rules. No other DDR generation will fit or function in this platform.

Registered 2Rx4 at 1.1 V

The single specification that decides compatibility is the registered 2Rx4 organisation running at 1.1 V with CL40 latency. This exact combination lets the memory controller address full capacity across all populated channels at the rated 4800 MT/s. A UDIMM, a different rank structure or a mismatched voltage would prevent the system from posting or force it to run at reduced speed.

Six-module population kit

The bundle provides six matched 64GB RDIMMs so every required slot can be filled in a single step. Pre-validated matching eliminates the risk of mixing modules with different timing or rank configurations that cause instability. Installers can follow the motherboard manual's population order without sourcing additional parts. No heat spreaders are included, so airflow planning remains the builder's responsibility.
