  • 768 GB total capacity from twelve 64 GB modules for dense server workloads
  • DDR5 5600 speed with CL46 latency delivers rated bandwidth for memory-intensive tasks
  • Registered ECC design with 2Rx4 organisation corrects single-bit errors and offloads the memory controller
  • 10 V operating voltage matches the Supermicro H14SSL-NT motherboard specification
  • 288-pin RDIMM form factor fits the board's registered DIMM slots exactly

Server-grade DDR5 ECC RDIMM kit

This 768GB kit delivers twelve 64GB DDR5 5600 registered ECC modules built to the exact rank, voltage and timing the Supermicro H14SSL-NT motherboard expects. It targets administrators who need full-capacity population on supported server platforms.

288-pin registered form factor for full-slot

The 288-pin RDIMM format matches the board's memory-controller requirements; it is not a UDIMM or SODIMM. Registered architecture offloads the controller so every slot can run fully populated at rated speed while ECC corrects single-bit errors before they reach production workloads.

Lifetime replacement and US-based technical support

The bundle includes a lifetime replacement warranty and free US-based technical support. Before installation, consult the system or motherboard manual for supported capacities, approved DIMM population order and installation steps to ensure correct configuration.

Questions about this item

Will the 1.1V operating voltage limit sustained throughput on a fully populated Supermicro H14SSL-NT?

The kit runs at the standard DDR5 1.10V. The registered design keeps every slot stable at the rated 5600 MT/s when all twelve 64GB modules are installed.

How much heat and power should I expect from twelve 64GB RDIMMs running 24/7?

Registered ECC modules draw only the 1.1V rail and have no heat spreaders, so total power stays within normal DDR5 RDIMM limits for a fully loaded server chassis.

Does the Supermicro H14SSL-NT need a specific BIOS revision or CPU stepping to recognise the full 768GB kit?

The kit is verified for the H14SSL-NT motherboard. Check the board manual for the approved DIMM population order and any required firmware version before installation.
