  • Verified fit for Supermicro H14SSL-NT motherboard with 288-pin RDIMM form factor

Exact-match upgrade for Supermicro H14SSL-NT

This 384GB kit contains six 64GB DDR5 RDIMM modules built to the exact rank, voltage and timing the Supermicro H14SSL-NT memory controller expects. Registered ECC architecture ensures every slot is recognised at full capacity and runs at its rated speed without manual tuning.

Sustained-load behaviour

Registered buffering offloads the memory controller so all six slots operate fully populated at DDR5 5600 without throttling. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during continuous production workloads.

Build and connectivity

Modules use a standard 288-pin RDIMM form factor with no heat spreader, relying on server chassis airflow for cooling. Major OEM Samsung, Micron or Hynix DRAM chips populate the 2Rx4 layout. Verify your motherboard manual for approved population order before installation.

Questions about this item

How much power does the 6x64GB DDR5 5600 kit draw at 1.1V running 24/7?

Each 64GB module operates at 1.10V; total draw depends on the Supermicro H14SSL-NT memory controller and load, but registered ECC RDIMMs are designed for stable full-population operation at rated voltage.

Does the Supermicro H14SSL-NT need a specific BIOS revision or CPU to accept this 384GB 2Rx4 kit?

The kit is spec-matched to the H14SSL-NT's 288-pin RDIMM slots and population rules; consult the board manual for approved DIMM order, maximum capacity per channel, and any required firmware version.

Can I mix these 2Rx4 CL46 RDIMMs with older DDR5 modules of different rank or speed?

Mixing ranks, speeds, or timings is not recommended; the registered ECC design expects uniform 2Rx4 CL46 modules across all populated slots for full 384GB stability.
