Supermicro H13DSG-O-CPU DDR5 upgrade

This 128 GB kit delivers two 64 GB DDR5-4800 registered ECC modules built to the exact rank, voltage and timing the Supermicro H13DSG-O-CPU memory controller expects. It targets administrators who need to populate every slot at full capacity without compatibility guesswork.

Capacity and headroom

Two dual-rank 64 GB RDIMMs provide 128 GB of registered ECC memory running at PC5-38400 with CL40 latency at 1.1 V. Registered buffering lets the board run fully populated at rated speed, while ECC corrects single-bit errors before they reach production workloads. The kit stops at 128 GB; systems requiring more memory per channel or higher frequencies will need a different solution.

Build and connectors

Modules use the 288-pin RDIMM form factor with major OEM DRAM and no heat spreader, relying on server chassis airflow for cooling. The registered design reduces electrical load on the memory controller, enabling stable operation across all populated slots. Buyers without a Supermicro H13DSG-O-CPU board or those needing UDIMM or SODIMM modules cannot use this kit.

Questions about this item

Will the 2Rx4 4800MHz registered ECC modules run alongside any existing DDR5 RDIMMs in the Supermicro H13DSG-O-CPU?

Yes, as long as the installed DIMMs are also DDR5 4800 registered ECC at 1.1V, the memory controller will train all slots at the rated speed; mixing ranks or speeds forces the slowest common setting.

How can I confirm the kit is recognised at 128GB and DDR5-4800 after installation?

Enter the BIOS or UEFI and check the memory information screen — it should show 128GB total, 4800MT/s data rate, CL40 latency and ECC enabled for each of the two 64GB modules.

Does the 2x64GB kit include heat spreaders or any cables, or must they be purchased separately?

The package contains only the two 288-pin RDIMM modules; no heat spreaders, cables or additional accessories are included.
