16GB DDR5 RDIMM for Supermicro H13DSG-O-CPU

This 16GB DDR5 4800MHz registered ECC module is built for the Supermicro H13DSG-O-CPU motherboard. It delivers 1Rx8 organisation at 1.1V with CL40 latency, matching the exact rank, voltage and timing the platform expects.

Verify DIMM population rules and capacity limits

Check your system or motherboard manual for supported capacities, approved DIMM population order and installation steps before ordering. The board requires 288-pin RDIMMs, not UDIMMs or SODIMMs, and population rules differ by configuration.

Registered ECC architecture protects data integrity

Registered buffering offloads the memory controller so every slot runs fully populated at rated speed, while ECC corrects single-bit errors on the fly to stop silent data corruption and unplanned reboots. The module ships without a heat spreader.

Questions about this item

Does the kit include only the 16GB DDR5 4800MHz CL40 RDIMM or are extra parts supplied?

The package contains a single 16GB DDR5 4800MHz CL40 1Rx8 ECC Registered RDIMM; no cables, brackets or additional modules are included.

Should I choose the 1Rx8 CL40 version or look for a different rank or latency for the Supermicro H13DSG-O-CPU?

This module matches the board's validated 1Rx8 Registered ECC profile at CL40 and 1.1V, so it will be recognised at full capacity and rated speed without further selection.

Will the 4800MHz PC5-38400 rating actually run at that speed once installed in the server?

Yes — the exact rank, voltage and timing align with the motherboard's memory controller, allowing the DIMM to operate at its full 4800MHz PC5-38400 specification.
