Server memory upgrade for Supermicro H14SSL-NT

This 32GB DDR5 RDIMM is built as an exact-match upgrade for the Supermicro H14SSL-NT motherboard. It delivers registered ECC operation at the controller's rated speed and voltage, so the system recognises the full capacity immediately. The module targets administrators who need reliable, validated memory for production servers.

DDR5 6400 registered ECC limits

The DDR5 6400 interface runs at 1.1V with a CL52 latency and a 2Rx8 registered layout. Registered buffering allows every slot to be populated at full capacity without overloading the memory controller, while ECC corrects single-bit errors on the fly. Modules without registered buffering or ECC will not meet the board's population rules.

32GB capacity and headroom

A single 32GB module provides substantial capacity for virtualisation, databases and compute workloads, and the registered design keeps stability high when all slots are filled. Workloads that demand more than 32GB per DIMM or require non-registered UDIMM or SODIMM form factors cannot use this module.

Questions about this item

Should I choose the 32GB DDR5 6400 CL52 2Rx8 RDIMM or a different capacity for my Supermicro H14SSL-NT?

This module is a 32GB DDR5 6400 CL52 2Rx8 1.1V ECC Registered RDIMM built as an exact-match upgrade for the Supermicro H14SSL-NT. Select it when you need a single 32GB stick that meets the board's registered ECC requirements.

What does the 6400MHz speed rating deliver once installed in the server?

The DDR5 6400 (PC5-51200) rating means the module runs at 6400 MT/s at CL52 latency and 1.1V when the motherboard's memory controller is populated according to its validated population rules.

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

The 288-pin Registered (RDIMM) form factor with ECC offloads the memory controller, allows full-capacity population of every slot, and corrects single-bit errors on the fly to prevent silent data corruption.
