Supermicro H13DSG-O-CPU-D DDR5 upgrade

This 64 GB DDR5-4800 registered ECC RDIMM is built to the exact rank, voltage and timing the Supermicro H13DSG-O-CPU-D motherboard expects. It installs as a single 288-pin module and is recognised at full capacity and rated speed.

Population rules and registered architecture

The board requires 288-pin RDIMM modules; UDIMM or SODIMM variants will not fit. Registered buffering offloads the memory controller so every populated slot runs at 4800 MT/s, while on-die ECC corrects single-bit errors before they reach production workloads.

Replacing slower or smaller DDR5 RDIMMs

Swapping out lower-capacity or lower-speed DDR5 RDIMMs adds 64 GB per slot and lifts bandwidth to PC5-38400 without changing voltage. The jump is worthwhile when the manual confirms the target population order and the workload needs maximum registered DIMM density.

Questions about this item

Will the CL40 latency hold steady when all slots are populated on the Supermicro H13DSG-O-CPU-D?

Yes, the registered 2Rx4 design offloads the memory controller so every slot runs at the rated DDR5-4800 CL40 timing even in a full population.

Does the module run hot or draw extra power during 24/7 server workloads?

At 1.1 V with no heat spreader the DIMM stays within standard DDR5 power limits and relies on normal chassis airflow for cooling.

Do I need a Supermicro H13DSG-O-CPU-D motherboard for this 64 GB kit to work?

The kit is validated for that exact board; other systems must support DDR5-4800 288-pin registered ECC with 2Rx4 rank and 1.1 V operation.
