Exact-match upgrade for Supermicro H14SSL-NT

This 16 GB DDR5 RDIMM is built to the precise rank, voltage, and timing the Supermicro H14SSL-NT memory controller expects. It installs as a registered ECC module so the server recognises the full capacity and runs at the rated 6400 MT/s speed without manual tuning.

DDR5 RDIMM limits

The 288-pin registered form factor is required by this motherboard; unbuffered UDIMMs or SODIMMs will not fit or function. Registered architecture buffers the command and address bus, allowing every slot to be populated at full capacity while ECC corrects single-bit errors on the fly to prevent silent data corruption.

Capacity and headroom

A single 16 GB 1Rx8 module delivers the stated density at 1.1 V with CL52 latency, suitable for typical virtualisation and database workloads on this platform. Total system capacity and maximum supported speed depend on the motherboard's qualified vendor list and DIMM population rules, so consult the manual before expanding beyond this module.

Questions about this item

Should I choose the 16GB DDR5 6400MHz CL52 1Rx8 ECC RDIMM or a different capacity for my Supermicro H14SSL-NT?

The Supermicro H14SSL-NT requires registered ECC RDIMMs at 1.1V; this 16GB DDR5 6400MHz CL52 1Rx8 module matches the board's exact rank, voltage and timing so it will be recognised at full capacity and run at rated speed.

What does the 6400MHz speed mean once the module is installed in the server?

The module operates at DDR5 6400 (PC5 51200) with CL52 latency at 1.1V, delivering the full data rate the memory controller expects when the board is populated according to its supported configuration.

Is the 288-pin RDIMM interface compatible with my motherboard and what does it limit in practice?

The 288-pin registered RDIMM form factor is the only type the Supermicro H14SSL-NT accepts; registered buffering offloads the memory controller so every slot can run fully populated at full capacity while ECC corrects single-bit errors on the fly.
