Exact-fit DDR5 ECC RDIMM upgrade

This 32GB NEMIX RAM module is a system-specific DDR5-4800 (PC5-38400) Registered ECC RDIMM built for the Supermicro H14DST-FL motherboard. It runs at 1.1V with CL40 timing and a 2Rx8 organisation across 288 pins, matching the board's memory-controller requirements precisely.

Suited for verified Supermicro H14DST-FL

Ideal for administrators populating approved DIMM slots on this exact motherboard where registered ECC memory is required. Not suitable for systems that accept only unbuffered UDIMMs or SODIMMs, platforms needing a different DDR generation, or builds where the manual specifies a different rank, voltage, or population order.

2Rx8 registered ECC at 1.1V decides fit

The single specification that determines compatibility is the 2Rx8 registered ECC architecture at 1.1V on a 288-pin DDR5 RDIMM. If your motherboard manual calls for this exact rank, buffering type, error-correction, and voltage combination the module will be recognised at full capacity and rated speed; otherwise it will not function.

Questions about this item

Does the kit include only the 32GB DDR5 4800 CL40 2Rx8 ECC RDIMM module or are extra parts supplied?

The package contains a single 32GB DDR5 4800MHz PC5-38400 2Rx8 1.1V CL40 288-pin ECC Registered RDIMM. No additional components are included.

Why is the 2Rx8 registered ECC version the correct choice for the Supermicro H14DST-FL instead of a UDIMM or SODIMM?

The H14DST-FL requires 288-pin registered RDIMMs; UDIMMs and SODIMMs are physically and electrically incompatible. The 2Rx8 organisation and 1.1V operation match the board's memory-controller expectations.

What does the CL40 4800MHz rating mean once the module is installed in the server?

The module runs at 4800 MT/s with a CAS latency of 40 cycles at 1.1V. The registered buffer and ECC let every slot operate fully populated at this rated speed while correcting single-bit errors.
