Exact-fit server memory kit

This 1.5 TB kit delivers twelve 128 GB DDR5 ECC RDIMMs built for the Supermicro H14SSL-N motherboard. Registered architecture and on-die error correction let every slot run fully populated at the rated 6400 MT/s without overclocking. System administrators who need maximum capacity on this specific platform get a validated, drop-in solution. Buyers using consumer boards or UDIMM-only platforms cannot use these modules.

DDR5-6400 2Rx4 registered ECC

The single specification that decides fitment is the 2Rx4 registered ECC profile at 1.1 V with CL52 timing. The memory controller on the H14SSL-N expects exactly this rank structure, voltage and latency; any deviation prevents the system from training at full speed or from recognising the full 1.5 TB capacity. The 288-pin RDIMM form factor is also mandatory — UDIMM or SODIMM variants will not seat in the server slots.

Sustained enterprise stability

Registered buffering offloads the memory controller so all twelve slots operate continuously at 6400 MT/s under heavy multi-threaded workloads. ECC corrects single-bit errors in real time, preventing silent data corruption during long-running database or virtualisation tasks. Without heat spreaders the modules rely on chassis airflow, which is standard in the target server platforms.

Questions about this item

What does the 6400 MT/s rating mean once the kit is installed in the Supermicro H14SSL-N?

The twelve 128 GB modules run at DDR5-6400 (PC5-51200) with CL52 latency and 1.1 V, so the board's memory controller recognises the full 1.5 TB at the rated data rate.

How does the 288-pin RDIMM interface and registered design affect real-world operation?

Registered buffering offloads the memory controller, letting all twelve slots stay populated at 128 GB each while ECC corrects single-bit errors on the fly.

What physical space and slot layout does the 12-module kit need on the H14SSL-N?

Twelve 288-pin DDR5 RDIMM slots must be free; the modules have no heat spreaders, so they fit standard DIMM spacing dictated by the motherboard's population rules.
