Exact-match DDR5-6400 server kit

This NEMIX RAM kit delivers 128 GB as two 64 GB DDR5-6400 Registered ECC RDIMMs built for the Supermicro H14SSL-N motherboard. The modules run at 1.1 V with CL52 latency and a 2Rx4 organisation, matching the board's memory controller requirements for full-capacity recognition at rated speed.

DDR5 RDIMM population constraints

Registered (buffered) architecture offloads the memory controller so every slot can run fully populated at full capacity, while ECC corrects single-bit errors on the fly to prevent silent data corruption. Server and motherboard memory support varies by model, so the system manual must be consulted for supported capacities, approved DIMM population order and installation steps before purchase.

2Rx4 rank and 1.1 V specification

The 2Rx4 rank structure and 1.1 V operating voltage are the decisive parameters that determine whether this kit will be recognised at its full 128 GB capacity and run at DDR5-6400 on the target platform. Buyers who need a different rank configuration or voltage level must select an alternative part.

Questions about this item

Should I pick the 2x64 GB kit or look for a single 128 GB module for the Supermicro H14SSL-N?

The board uses 288-pin RDIMM slots and the kit provides two 64 GB modules; a single 128 GB RDIMM is not offered in this lineup.

Will the DDR5-6400 rating actually run at 6400 MT/s once installed in the H14SSL-N?

The modules are spec-matched to the motherboard's memory controller, so the system recognises the full 128 GB and operates at the rated 6400 speed.

Does the PC5-51200 label limit the bandwidth I can use on this server?

PC5-51200 is the peak transfer rate for DDR5-6400; the registered ECC design lets every populated slot sustain that bandwidth.
