Exact-Match DDR5 RDIMM for Supermicro H14DSH

This 16 GB DDR5-4800 registered ECC module is built to the precise rank, voltage and timing the H14DSH memory controller expects. It installs as a single 288-pin RDIMM so the server recognises the full capacity at its rated speed.

Verify DIMM population rules before ordering

Consult the Supermicro H14DSH manual for supported capacities, approved slot population order and installation steps. The board requires registered RDIMMs — not UDIMMs or SODIMMs — and population rules differ by configuration.

Registered architecture with ECC at 1.1 V

The registered buffer offloads the memory controller, allowing every populated slot to run at full capacity. On-die ECC corrects single-bit errors on the fly, preventing silent data corruption. The module operates at 1.1 V with no heat spreader, so airflow across the DIMM slots handles thermals.

Questions about this item

Does the package include anything besides the single 16 GB DDR5 4800 CL40 1Rx8 ECC RDIMM, or must I buy extra modules separately?

The package contains one 16 GB DDR5 4800 CL40 1Rx8 ECC Registered RDIMM. No additional modules, heat spreaders or cables are included; buy more DIMMs separately if your configuration needs them.

My Supermicro H14DSH has multiple DDR5 slots — should I choose this 16 GB 1Rx8 CL40 RDIMM or a different capacity or rank?

This 16 GB 1Rx8 CL40 RDIMM matches the board's qualified DDR5 4800 Registered ECC spec. Check your motherboard manual for the approved population order and maximum capacity per slot before choosing a different size or rank.

Once installed in the H14DSH, will the module actually run at the rated 4800 MT/s and CL40 timings?

Yes — the DIMM is spec-matched to the H14DSH's DDR5 4800 Registered ECC requirements, so the memory controller will recognise it at full 4800 MT/s with CL40 latency when populated according to the board's rules.
