Exact-match DDR5 ECC RDIMM kit for Supermicro H13SSH

This 32GB kit contains two 16GB DDR5 4800 RDIMM modules built to the precise 1Rx8 rank, 1.1V voltage and CL40 timing the H13SSH memory controller expects. Registered ECC architecture offloads the controller and corrects single-bit errors on the fly. The 288-pin form factor matches the board's DIMM slots exactly.

Who this suits and who should look elsewhere

Server administrators upgrading a Supermicro H13SSH system that requires registered ECC DDR5 RDIMMs will find this kit validated for full-capacity population. Builders needing unbuffered UDIMMs, SODIMMs, non-ECC memory, or a different DDR generation cannot use these modules.

Build integration: what it needs and what it frees

Installation follows the motherboard manual's approved DIMM population order; no extra cooling or voltage adjustment is required beyond the standard 1.1V spec. Registered buffering lets every slot run fully populated at rated speed, freeing the memory controller from electrical loading while ECC prevents silent data corruption and unplanned reboots in production workloads.

Questions about this item

Does the Supermicro H13SSH motherboard need an available 288-pin DDR5 RDIMM slot for this kit?

Yes, the kit uses the 288-pin DDR5 RDIMM form factor that the H13SSH requires, so at least one compatible slot must be free.

Can I mix these 1Rx8 CL40 1.1V modules with existing DDR5 RDIMMs of a different rank or speed on the same board?

Mixing different ranks or speeds is not recommended; the H13SSH memory controller expects matched modules for stable operation at 4800 MT/s.

How can I confirm the system recognises the full 32 GB at 4800 MT/s with ECC active after installation?

Check the BIOS memory summary or run a tool such as dmidecode; it should show 32 GB total, 4800 MT/s, and ECC enabled for each DIMM.
