Exact-match DDR5 kit for Supermicro H14SSF

This 512 GB kit contains eight 64 GB DDR5 6400 RDIMMs built to the precise rank, voltage and timing the server's memory controller expects. It is intended for administrators who need to populate every slot on a compatible Supermicro H14SSF motherboard with registered ECC memory that runs at its rated speed without manual tuning.

Registered 2Rx4 ECC at 1.1 V

Each module is a 288-pin DDR5 RDIMM with CL52 latency, 1.10 V operating voltage and a 2Rx4 organisation. The registered architecture buffers address and command signals so the memory controller can drive a fully populated configuration reliably, while on-die ECC corrects single-bit errors before they affect workloads.

Eight-module population fills every slot

The kit delivers the full 512 GB capacity supported by the validated motherboard when all DIMM sockets are occupied. Adding further memory is not possible on this platform, and workloads that exceed this limit will require a different server configuration.

Questions about this item

Will the DDR5-6400 speed run at 6400 MT/s once installed in my Supermicro H14SSF?

Yes, the kit is spec-matched to the H14SSF so the memory controller recognises the exact rank, voltage and timing, allowing all eight modules to operate at the rated 6400 MT/s.

Does the registered ECC RDIMM interface limit how many modules I can populate on this board?

The registered architecture offloads the memory controller, enabling every slot to be fully populated at full capacity while ECC corrects single-bit errors on the fly.

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

Yes, the 288-pin registered RDIMM form factor is exactly what the H14SSF requires; they are not UDIMM or SODIMM and match the board's population rules.
