Exact DDR5-4800 RDIMM for Supermicro H14DSG-O-CPU

This 16GB registered ECC module matches the precise rank, voltage and timing the Supermicro H14DSG-O-CPU memory controller expects. It installs as a direct drop-in upgrade so the system recognises the full capacity at its rated speed. Built for servers and workstations that require validated memory population.

288-pin registered form factor with ECC

The 288-pin RDIMM layout fits only motherboards wired for registered DDR5; it will not seat in UDIMM or SODIMM slots. Registered buffering offloads the memory controller to allow every slot to run fully populated, while on-die ECC corrects single-bit errors before they reach production workloads. No heat spreader is fitted, so airflow across the PCB is unrestricted.

DDR5 4800 CL40 1.1V limits

The JEDEC DDR5-4800 standard caps this module at 4800 MT/s with CL40 latency at 1.1V; higher speeds or tighter timings need a motherboard and CPU combination that officially supports them. Population rules differ by platform, so the system manual must be consulted for approved DIMM order and maximum capacity per channel. Mixing ranks or voltages can prevent the server from posting.

Questions about this item

Does PC5-38400 set the real-world speed ceiling for this DDR5 module?

The module is rated DDR5 4800, which is the maximum JEDEC speed this memory controller will negotiate; PC5-38400 is the matching peak-bandwidth label.

Will this 288-pin RDIMM seat in the Supermicro H14DSG-O-CPU DIMM slots?

Yes, the board requires 288-pin registered DIMMs and this module matches that exact form factor, so it fits the slots without adapters.

What is the correct population order when installing this 1Rx8 ECC RDIMM?

Consult the Supermicro H14DSG-O-CPU manual for the approved DIMM population sequence; the board's memory rules dictate which slots must be filled first.
