Server memory kit for Supermicro H13DSG-O-CPU-D

This 576GB kit delivers twelve 48GB DDR5 4800 RDIMM modules rated at CL40 and 1.10V. It is built for administrators who need the exact registered ECC configuration that the Supermicro H13DSG-O-CPU-D motherboard expects for full-capacity operation.

Registered ECC design for full-slot populations

The 288-pin RDIMM form factor matches the board's registered memory requirement; UDIMM or SODIMM modules will not work. Registered buffering offloads the memory controller so all twelve slots can run populated at the rated 4800 speed, while on-die ECC corrects single-bit errors before they affect production workloads.

Twelve-module kit simplifies deployment

The package contains the complete 12 x 48GB set matched to the board's population rules, removing the need to source individual DIMMs or verify rank and voltage per stick. Installers follow the motherboard manual for slot order and BIOS settings, then the system recognises the full 576GB at its rated timings without further tuning.

Questions about this item

Will the registered ECC design keep single-bit errors from crashing the Supermicro H13DSG-O-CPU-D under sustained load?

Registered buffering offloads the memory controller so all twelve slots run fully populated at 576 GB, while on-die ECC corrects single-bit errors on the fly before they reach production workloads.

Does the kit run warm without a heat spreader when installed in a 288-pin RDIMM chassis all day?

The modules operate at the standard DDR5 1.10 V with no heat spreader, relying on server chassis airflow to keep temperatures stable under continuous operation.

Must the Supermicro H13DSG-O-CPU-D motherboard already support DDR5-4800 PC5-38400 registered DIMMs for this kit to work?

Yes — the board must accept 288-pin DDR5 RDIMMs at 4800 MT/s, 1.10 V, CL40, 2Rx8 registered ECC; verify the manual for supported capacities and population order before installing.
