  • 384 GB total capacity from eight 48 GB modules for high-density server workloads
  • DDR5 4800 MT/s speed with CL40 latency matches the board's rated timing
  • Registered ECC architecture offloads the memory controller and corrects single-bit errors
  • 1 V operating voltage and 2Rx8 organisation meet the Supermicro H14SSL-NT specifications
  • 288-pin RDIMM form factor ensures correct physical fit in every populated slot

384GB DDR5 4800 ECC RDIMM Kit

This 384GB kit contains eight 48GB DDR5 4800 Registered ECC RDIMMs built for the Supermicro H14SSL-NT motherboard. Each module runs at 1.1V with CL40 latency and a 2Rx8 organisation. The registered design lets the memory controller drive a fully populated system without signal degradation.

Who should use this kit

Server administrators expanding a Supermicro H14SSL-NT platform to its maximum supported capacity will match the board's exact voltage, rank and timing requirements. Buyers needing unbuffered UDIMMs, SODIMMs, non-ECC memory or a different DDR generation cannot use these modules.

288-Pin DDR5 RDIMM form factor

The 288-pin Registered DIMM form factor is the only type the H14SSL-NT memory slots accept. UDIMM or SODIMM variants will not seat or function. Verify the motherboard manual for approved population order before installation.

Questions about this item

Does the 288-pin RDIMM form factor fit the Supermicro H14SSL-NT motherboard slots?

Yes, the kit uses the 288-pin Registered RDIMM form factor required by the Supermicro H14SSL-NT motherboard, matching the board's DDR5 memory slots exactly.

What is the correct population order when installing all eight 48GB modules?

Fill the DIMM slots following the sequence shown in the Supermicro H14SSL-NT manual; the board's population rules dictate which channels must be populated first for full 384GB operation.

Will the modules require active cooling or thermal pad replacement over time?

No, the modules have no heat spreader and run at the standard 1.1V DDR5 voltage, so they rely on normal chassis airflow and need no thermal maintenance.
