  • 512 GB kit (4 × 128 GB) lets you fully populate the Supermicro H13DSG-OM
  • DDR5 5600 PC5-44800 speed runs at the board's rated frequency
  • CL46 latency and 1.1 V voltage match the controller's exact timing spec
  • Registered ECC 2Rx4 design offloads the controller and corrects single-bit errors
  • 288-pin RDIMM form factor fits the motherboard's required slot type

Supermicro H13DSG-OM memory kit

This 512GB DDR5 kit contains four 128GB Registered ECC RDIMMs built to the exact specifications of the Supermicro H13DSG-OM motherboard. It targets administrators who need maximum capacity per slot for virtualization, database, or high-performance computing workloads.

Registered ECC RDIMM fitment

Each module uses the 288-pin RDIMM form factor with a 2Rx4 organization that the board's memory controller expects when fully populated. Registered buffering reduces electrical load on the controller so all four slots run at the rated 5600 MT/s speed, while on-die ECC corrects single-bit errors before they affect system stability.

512GB capacity ceiling

The four-module kit delivers 512GB total at CL46 latency and 1.1V operation, filling every DIMM slot the H13DSG-OM provides. Builds requiring more memory than this board supports will need a different platform, and workloads that demand lower latency than CL46 or higher frequency than 5600 MT/s exceed this kit's rated limits.

Questions about this item

Will the CL46 latency become a bottleneck when all four 128 GB modules run continuously at DDR5-5600?

CL46 is the rated timing at 5600 MT/s; the registered buffer and ECC keep every slot stable at full capacity without further latency penalties.

How much heat and power should I expect from a fully populated 512 GB kit running 24/7?

Each module draws 1.1 V with no heat spreader; registered architecture offloads the memory controller, so total heat stays within standard server airflow limits.

Does the Supermicro H13DSG-OM require a specific BIOS revision or CPU stepping to recognise this 2Rx4 RDIMM kit?

The kit is spec-matched to the board's 288-pin RDIMM population rules; consult the motherboard manual for approved DIMM order and capacity limits before installing.
