Supermicro H14SSL-NT DDR5 upgrade

This 64 GB DDR5 module is built for the Supermicro H14SSL-NT motherboard. It delivers registered ECC memory in the 288-pin RDIMM form factor that the board requires. System administrators expanding server capacity will find the exact electrical and mechanical match.

Registered 2Rx4 CL40 at 1.1 V

The module operates as a 2Rx4 registered DIMM with CL40 latency at 1.10 V. This rank, voltage and timing combination is what the memory controller expects for full-speed operation. A UDIMM or different rank configuration would not be recognised at rated speed.

64 GB per slot headroom

Each slot accepts a single 64 GB DIMM so total capacity scales with the number of populated sockets. Registered buffering lets every slot run fully populated without loading the controller. Builds needing more than the board's maximum supported slots will need a different platform.

Questions about this item

Will the DDR5 4800 speed run at 4800 MT/s on my Supermicro H14SSL-NT?

The module is spec-matched to the H14SSL-NT memory controller, so it is recognised at full capacity and runs at its rated 4800 MT/s when installed in the approved slots.

What does the PC5-38400 label tell me about this RDIMM?

PC5-38400 is the DDR5 4800 JEDEC designation for this 288-pin registered ECC module, confirming the speed grade and pinout the board requires.

Does the 288-pin RDIMM fit the H14SSL-NT DIMM slots without adapters?

Yes, the 288-pin registered form factor matches the H14SSL-NT motherboard slots exactly; no UDIMM or SODIMM adapter is needed.
