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.

Questions about this item

How does the 384 GB kit behave when all six slots of a Supermicro H14SSF are populated?

The registered ECC design lets the memory controller drive every slot at the rated DDR5-4800 speed with CL40 timing and 1.1 V, so the full 384 GB is recognised and stable.

What does the PC5-38400 rating limit in everyday use?

It caps the data rate at 4800 MT/s; the module will not run faster unless the platform supports a higher JEDEC speed and the BIOS is configured for it.

Will these 288-pin RDIMMs fit the DIMM slots on a Supermicro H14SSF motherboard?

Yes, the 288-pin registered form factor matches the board's DDR5 RDIMM sockets exactly; UDIMM or SODIMM modules would not seat.
