Exact DDR5-6400 RDIMM kit

This NEMIX RAM kit delivers 128GB of DDR5 server memory as four 32GB Registered ECC modules. Each 288-pin RDIMM operates at 6400MT/s with CL52 latency and a low 1.1V supply. The 2Rx8 rank structure matches the density and timing profile that registered server platforms expect for full-capacity operation.

For Supermicro H14SSL-N builds

The kit is validated for the Supermicro H14SSL-N motherboard, so installers avoid the trial-and-error of generic module qualification. Registered buffering and on-die ECC protect data integrity in always-on workloads. Builders using consumer boards, laptops, or any system that requires unbuffered UDIMMs or SODIMMs cannot use these modules.

Registered ECC DDR5 at 1.1V

The single specification that decides fitment is the Registered ECC DDR5 RDIMM interface running at 1.1V. Only motherboards wired for 288-pin DDR5 RDIMMs with registered clock drivers and ECC support will recognise the kit at its rated 6400 speed and 128GB total capacity.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H14SSL-N motherboard slots?

Yes, the kit uses the exact 288-pin Registered DDR5 form factor the H14SSL-N requires; it is not a UDIMM or SODIMM and matches the board's physical slot keying.

What population order should I follow when installing the four 32 GB sticks?

Consult the H14SSL-N manual for the approved DIMM population sequence; the board's memory-controller rules dictate which slots must be filled first for full 128 GB recognition.

Do these modules have heat spreaders that could block adjacent CPU coolers?

No, the DIMMs are supplied without heat spreaders, so they present a low profile that clears most server heatsinks and airflow paths.
