64GB DDR5-5600 RDIMM for Supermicro H14SSL-NT

This 64GB DDR5 5600MHz PC5-44800 registered ECC module is built for the Supermicro H14SSL-NT motherboard. It delivers the exact 2Rx4 rank structure, 1.1V voltage and CL46 timing the platform expects. Server administrators upgrading memory capacity in validated configurations will find it matches the board's population rules.

288-pin registered form factor with major OEM chips

The 288-pin RDIMM design uses Samsung, Micron or Hynix components without a heat spreader, fitting standard server DIMM slots. Registered buffering reduces electrical load on the memory controller when all slots are populated, while on-die ECC corrects single-bit errors to prevent silent data corruption. The module installs directly into the H14SSL-NT's DDR5 slots following the manual's population order.

Replaces lower-capacity or slower DDR5 RDIMMs

This kit upgrades systems running smaller registered DIMMs or slower DDR5 speeds, adding 64GB per slot at the full 5600MT/s data rate. The jump is worthwhile when your workload needs maximum registered capacity per channel and the motherboard manual confirms support for this density and rank. It does not fit boards requiring UDIMM, SODIMM or non-ECC memory.

Questions about this item

What speed does the DDR5 5600 interface actually run at on the Supermicro H14SSL-NT?

The module operates at DDR5 5600 (PC5-44800) with CL46 latency at 1.1V, delivering the exact data rate the motherboard's memory controller expects when populated per its rules.

What physical slot and form factor does this 64 GB RDIMM require?

It uses a 288-pin DDR5 RDIMM form factor; the board needs a registered DIMM slot, not a UDIMM or SODIMM socket, and the 2Rx4 rank must follow the manual's population order.

How is the module installed and which step is most often missed?

Power down, open the chassis, align the 288-pin key with the RDIMM slot, press firmly until both latches click, then verify the BIOS recognises the full 64 GB at 5600 MT/s — skipping the population-order check is the common error.
