NEMIX RAM 16GB DDR5 4800MHz ECC RDIMM 1Rx8 CL40 1.1V Supermicro H14SSL-NT memory upgrade

16GB DDR5-4800 RDIMM for Supermicro H14SSL-NT

This 16GB registered ECC module runs at 4800MHz with CL40 latency and 1.1V operation. It is built for the Supermicro H14SSL-NT motherboard where the memory controller expects a 1Rx8 registered DIMM. The 288-pin DDR5 form factor matches the board's slot requirements exactly.

Verified fitment and registered ECC stability

The module uses major OEM chips from Samsung, Micron, or Hynix in a registered architecture that buffers address and command signals. This lets the server populate every supported slot at full rated capacity while ECC corrects single-bit errors on the fly. The exact rank, voltage, and timing match the board's memory-population rules.

Straightforward server DIMM installation

Align the key notch on the 288-pin edge connector with the slot and press firmly until the retention clips engage. Servers often require a specific population order across channels, so consult the motherboard manual for the approved sequence before seating the module. A mismatched DIMM type or incorrect slot order will prevent the system from posting.

Not for non-ECC or unbuffered platforms

This RDIMM will not work in desktop boards, workstations, or laptops that require unbuffered UDIMM or SODIMM modules. Systems without registered ECC support cannot use this memory. Buyers needing standard consumer DDR5 or higher-capacity registered kits should look elsewhere.
