Exact-match DDR5-5600 ECC RDIMM for Supermicro

This 48GB DDR5 5600MHz CL46 2Rx8 1.1V 288-pin ECC Registered RDIMM is built as an exact-match upgrade for the Supermicro H14SSL-NT motherboard. It delivers the precise rank, voltage and timing the server's memory controller expects for full-capacity recognition at rated speed.

Verified fitment and population rules

The 288-pin Registered form factor matches the board's physical and electrical requirements; UDIMM or SODIMM modules will not work. Server memory support varies by model, so consult your system or motherboard manual for supported capacities, approved DIMM population order and installation steps before purchase.

DDR5 Registered ECC stability limits

Registered architecture offloads the memory controller so every slot runs fully populated at full capacity, while ECC catches and corrects single-bit errors on the fly. The module operates within the DDR5 5600 (PC5 44800) standard at 1.10V CL46; exceeding the board's validated population rules or mixing ranks can prevent the system from reaching its rated speed.

Questions about this item

How do I verify the 48GB DDR5 5600MHz CL46 RDIMM is running at its rated speed after installation?

Check the BIOS or UEFI memory information screen; it should show 5600 MT/s, CL46 timings, 1.1V voltage, and 48GB total capacity with ECC and registered status active.

What comes in the box and do I need to buy anything else for the Supermicro H14SSL-NT?

The package includes one 48GB 288-pin DDR5 ECC Registered RDIMM; no extra cables, brackets, or heat spreaders are required for installation in the H14SSL-NT.

Should I choose a different capacity or rank for the H14SSL-NT or is this 48GB 2Rx8 kit the right match?

This 48GB 2Rx8 module matches the exact rank, voltage, and timing the H14SSL-NT expects; consult your motherboard manual for approved population order and maximum supported capacity per slot.
