32GB DDR5-4800 ECC RDIMM

This NEMIX RAM module delivers 32GB of DDR5-4800 memory in a 288-pin Registered DIMM format. It operates at 1.10V with CL40 latency and features 2Rx8 organisation with on-die ECC for data integrity. The part is built for the Supermicro H13SSF motherboard where registered memory is required.

Suits populated Supermicro H13SSF builds

The registered design and ECC function match the H13SSF memory controller, so every slot can be filled at the rated 4800 speed. Builders using unbuffered UDIMMs or non-ECC modules should look elsewhere because the board will not accept them.

288-pin Registered DDR5 form factor

The module uses the 288-pin RDIMM interface that the H13SSF requires. A UDIMM or SODIMM will not fit the socket, so this physical specification is the single detail that decides compatibility.

Questions about this item

How much power does each 32 GB DDR5 4800 CL40 1.10 V registered DIMM draw when the server runs continuously?

Each module operates at 1.10 V; total power depends on the Supermicro H13SSF memory controller and workload, so consult the board manual for per-slot figures.

What motherboard slot type must the H13SSF provide for this 288-pin RDIMM to be recognised at full 32 GB capacity?

The board needs a DDR5 288-pin RDIMM slot that supports registered ECC memory and the 2Rx8 rank configuration listed for this kit.

Will this CL40 4800 MT/s kit run at rated speed if I keep older DDR5 RDIMMs in other slots of the same H13SSF?

Mixing ranks, speeds or voltages can force the controller to down-clock all slots; populate every channel with identical 2Rx8 1.10 V CL40 modules to maintain 4800 MT/s operation.
