576 GB DDR5 ECC RDIMM kit for Supermicro H13SSH

This twelve-module kit delivers 576 GB of registered DDR5 memory built for the Supermicro H13SSH motherboard. Each 48 GB DIMM uses a 2Rx8 organisation, ECC protection and a 1.1 V operating voltage to meet the board's exact electrical and population requirements.

Capacity and headroom at 48 GB per module

Twelve 48 GB modules fill every slot on the H13SSH, providing the maximum supported density for memory-intensive workloads such as virtualisation, in-memory databases and large-scale analytics. The registered design keeps signal integrity stable across all populated channels, while ECC corrects single-bit errors before they affect production data.

DDR5-5600 interface limits

The kit runs at the DDR5-5600 (PC5-44800) speed with CL46 latency that the H13SSH memory controller specifies. Bandwidth and latency are fixed by this standard; workloads needing higher throughput or lower latency would require a platform that supports faster DDR5 data rates.

Questions about this item

Will the 12 48GB DDR5 5600 RDIMMs populate all slots on my Supermicro H13SSH without downclocking?

The kit is verified for the H13SSH and matches the board's 288-pin RDIMM requirement, 2Rx8 rank structure, 1.1V voltage and CL46 timing so the memory controller recognises the full 576GB at rated speed.

How can I confirm the 576GB DDR5 5600 ECC kit is running at CL46 1.1V after installation?

Check the BIOS memory information screen — it should show 5600 MT/s, CL46, 1.1V and ECC active across all 12 modules.

Does the 12-module 576GB package include anything besides the DDR5 RDIMMs?

The package contains only the 12 x 48GB DDR5 5600 CL46 1.1V 2Rx8 ECC RDIMMs; no heat spreaders, cables or additional accessories are included.
