Exact-match DDR5 kit for Supermicro H14SSL-NT

This 256GB kit delivers eight 32GB DDR5-4800 registered ECC RDIMMs built to the precise rank, voltage and timing the H14SSL-NT memory controller expects. It targets administrators who need the board to recognise every slot at rated speed without manual tuning.

Capacity and headroom

Eight dual-rank modules populate all available channels at 1.1V and CL40, giving the full 256GB the platform supports when fully loaded. The registered design keeps the memory controller stable under sustained load, while ECC corrects single-bit errors before they reach production workloads.

Verified fitment and support

The kit is validated for the 288-pin RDIMM form factor the H14SSL-NT requires, eliminating the risk of UDIMM or SODIMM mismatch. Lifetime replacement coverage and US-based technical support back the installation, though buyers must still confirm population order and capacity limits in their system manual before ordering.
