Exact-Match DDR5 Kit for Supermicro H13SSH-E

This 256 GB kit contains 16 modules of 16 GB DDR5-4800 Registered ECC RDIMM memory. It is built for the Supermicro H13SSH-E motherboard and matches the board's required rank, voltage, and timing so the controller recognises full capacity at rated speed.

Thermals and Power at 1.1 V

Each module operates at 1.1 V without a heat spreader, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping maintain stable operation when all 16 slots are populated.

Build Integration and Slot Population

The 288-pin RDIMM form factor fits only motherboards that accept Registered DDR5 DIMMs; it will not work in UDIMM or SODIMM slots. Consult the system manual for supported capacities and the approved DIMM population order before installation.

Questions about this item

How do I install the 16 RDIMMs in the Supermicro H13SSH-E and which slot order avoids the common population mistake?

Populate all 16 DDR5 slots following the H13SSH-E manual's exact DIMM sequence; the board requires Registered ECC RDIMMs in a specific channel order so every 1Rx8 module is recognised at 4800 MT/s.

What maintenance or replacement will the 256 GB kit need during its service life?

No routine maintenance is required; the modules have no heat spreaders and run at 1.1 V, so only a failed DIMM would need swapping under the lifetime replacement warranty.

What limit appears first when the 16 x 16 GB kit runs sustained workloads on the H13SSH-E?

The memory controller's maximum supported capacity and ranked-population rules cap usable memory before thermal or voltage headroom becomes an issue.
