Supermicro H13SSH-E DDR5 kit

This 768GB kit contains six 128GB DDR5 4800 RDIMM modules built for the Supermicro H13SSH-E motherboard. It targets administrators who need the full registered ECC capacity this platform accepts in a single validated package.

Replaces partial or mixed-capacity sets

When a server runs with fewer than six DIMMs or mixes ranks, the memory controller cannot use its maximum bandwidth or total addressable space. Installing all six matched 2Rx4 modules at once restores the full 768GB at the rated 4800MT/s speed with CL40 timing and 1.1V operation.

Handles memory-bound databases

The 768GB ceiling supports large in-memory datasets, dense VM fleets and checkpoint-heavy workloads without swapping. Workloads that exceed this capacity or require faster than DDR5-4800 transfer rates will need a platform that supports higher-density modules or newer memory standards.

Questions about this item

Will these 288-pin RDIMMs fit the Supermicro H13SSH-E motherboard slots?

Yes, the kit uses the 288-pin DDR5 RDIMM form factor that the H13SSH-E requires. It is not a UDIMM or SODIMM, so it matches the board's physical slot keying exactly.

What is the correct population order for the six 128 GB modules on the H13SSH-E?

Follow the motherboard manual's approved DIMM population sequence; the board's memory-controller rules dictate which of its slots must be filled first for all six 2Rx4 registered modules to be recognised at full 768 GB capacity.

Do these registered ECC modules need any periodic maintenance or component replacement?

No, solid-state DDR5 RDIMMs have no moving parts or user-serviceable components. The on-die ECC corrects single-bit errors automatically, and the modules run at 1.1 V for their service life without requiring replacement.
