  • 288-pin RDIMM form factor fits the exact slot type the board requires

Exact-fit DDR5 ECC RDIMM for Supermicro H14SSL-NT

This 32 GB kit contains two 16 GB DDR5-4800 registered DIMMs built to the precise 1Rx8 rank, 1.1 V voltage and CL40 timing the motherboard expects. The modules are tested for full-speed recognition and stable operation in every supported slot.

Who this suits and who should look elsewhere

Server administrators upgrading or populating a Supermicro H14SSL-NT platform with registered ECC memory will find the correct form factor and validated specifications here. Builders needing unbuffered UDIMMs, SODIMMs, non-ECC modules or capacities beyond the board's qualified list should select a different product.

What the kit changes for your build

The matched pair enables dual-channel bandwidth at the rated 4800 MT/s while registered buffering reduces electrical load on the memory controller. On-die ECC corrects single-bit errors in real time, protecting data integrity without additional software or configuration steps.

Questions about this item

Do I need a Supermicro H14SSL-NT motherboard with DDR5 RDIMM slots for this kit to work?

Yes, the 288-pin DDR5 Registered DIMMs are validated for the Supermicro H14SSL-NT and require that board's DDR5 RDIMM slots to operate.

Can I populate the remaining slots with other DDR5 4800 1Rx8 ECC RDIMMs?

The registered architecture lets every slot run fully populated at DDR5 4800, so matching 1Rx8 ECC RDIMMs can be added following the board's population rules.

How do I confirm the kit runs at DDR5 4800 CL40 1.1V after installation?

Check the BIOS memory information or a tool such as dmidecode; it should report 4800 MT/s, CL40, 1.10 V and 32 GB total across both modules.
