Exact-Match DDR5-5600 ECC RDIMM for Supermicro

This 16 GB registered DDR5 module is built to the precise rank, voltage and timing the Supermicro H14SSL-N memory controller expects. It installs as a single 288-pin RDIMM and runs at the rated 5600 MT/s speed with CL46 latency. The ECC and registered design targets servers and workstations that require error correction and full-slot population stability.

Registered DDR5 population rules

The module uses a registered (buffered) architecture at 1.1 V, which offloads the memory controller so every slot can run fully populated at the rated frequency. Mixing registered and unbuffered DIMMs is not supported, and the board's memory-population order must be followed to achieve the rated speed. Only DDR5 RDIMMs with matching rank and timing will be recognised at full capacity.

Verify board manual for slot order

Before ordering, consult the Supermicro H14SSL-N manual for supported capacities per slot, approved DIMM population sequence and any BIOS version requirements. The system may limit total memory or require specific slot filling patterns that affect whether this 16 GB module can be used alone or in combination with other modules.

Questions about this item

Should I choose a 1Rx8 or 2Rx8 rank for my Supermicro H14SSL-N?

This module is 1Rx8. The motherboard's manual lists the supported ranks per slot; match that rank to keep every channel running at 5600 MT/s.

What does the 5600 MT/s rating deliver once the module is installed in the server?

The board's memory controller will run this RDIMM at DDR5-5600 (PC5-44800) with CL46 latency at 1.1 V, giving the rated throughput when populated per the manual.

How does the 288-pin RDIMM interface limit speed or capacity on this platform?

The 288-pin Registered DIMM form factor is required by the H14SSL-N; it enables full-capacity population across all slots while the registered buffer keeps signal integrity at 5600 MT/s.
