Exact-fit DDR5 upgrade for Supermicro H13DSG-OM

This 512GB kit delivers sixteen 32GB DDR5-4800 RDIMM modules built to the motherboard's exact specifications. Registered ECC architecture with 2Rx8 organisation and 1.1V operation matches the memory controller requirements for full-capacity recognition. The CL40 timing and PC5-38400 rating ensure rated-speed operation across all populated slots.

Capacity and headroom: 512GB across sixteen slots

Sixteen 32GB modules fill every DIMM position on the H13DSG-OM, providing maximum registered memory capacity for virtualisation hosts, database servers and compute clusters. Registered buffering allows stable operation with all slots populated, while ECC corrects single-bit errors before they affect workloads. The kit reaches its limit when applications demand more than 512GB or faster than DDR5-4800 transfer rates.

Thermals, noise and power in normal use

Bare modules without heat spreaders rely on server chassis airflow for cooling, adding no acoustic profile of their own. At 1.1V the DDR5 voltage reduces per-module power draw compared to previous generations, keeping thermal load predictable in dense configurations. Power consumption scales linearly with all sixteen modules active under sustained memory-intensive workloads.

Questions about this item

Will the 16x32GB DDR5 4800 CL40 2Rx8 RDIMM ECC kit run at full 4800 speed in all 16 slots of my Supermicro H13DSG-OM?

The kit is spec-matched to the H13DSG-OM memory controller and population rules, so every slot runs fully populated at the rated 4800 speed with CL40 timings.

How can I confirm the 512GB DDR5 4800 ECC RDIMM kit is operating correctly after installation?

Enter the BIOS or use a tool like IPMI to verify all 16 modules show 32GB each at 4800 MT/s, CL40, 1.1V, and that ECC and registered status are reported.

Does the 512GB 16x32GB DDR5 4800 CL40 RDIMM ECC kit include heat spreaders or any extra cables?

The modules ship without heat spreaders and the package contains only the 16 RDIMMs; no cables or additional accessories are included.
