Supermicro H13SSH-E memory kit

This 256 GB kit supplies eight 32 GB DDR5-4800 RDIMMs built to the exact rank, voltage and timing the Supermicro H13SSH-E motherboard expects. It is designed for administrators who need the full 256 GB capacity recognised immediately without manual tuning. Builders using a different motherboard or a consumer platform should look elsewhere because the registered ECC pin-out and population rules are specific to this server board.

Capacity and headroom

Eight dual-rank modules deliver 256 GB of registered ECC memory at CL40 and 1.1 V, letting a fully populated H13SSH-E run every slot at the rated DDR5-4800 speed. The registered buffer offloads the memory controller so all channels remain stable at maximum capacity, while ECC corrects single-bit errors before they affect production workloads. Workloads that require more than 256 GB or faster than 4800 MT/s cannot be satisfied by this kit.

Build integration

Each module uses the 288-pin RDIMM form factor required by the H13SSH-E, so no UDIMM or SODIMM alternative will fit. The kit arrives as a matched set of eight, eliminating the need to source individual sticks or verify rank consistency across separate purchases. Installers must still consult the motherboard manual for the approved population order and any BIOS settings before seating the modules.

Questions about this item

Will this 256GB DDR5 4800 kit work with the Supermicro H13SSH-E motherboard I already own?

Yes, the kit is verified for the Supermicro H13SSH-E and uses the 288-pin RDIMM form factor that board requires, so it installs in the existing DIMM slots without modification.

How can I confirm the modules are running at DDR5 4800 with ECC active after installation?

Enter the BIOS or use a tool such as dmidecode on Linux to verify the speed reads 4800 MT/s, the voltage shows 1.10 V, and ECC status reports enabled for each of the eight 32 GB modules.

Does the box contain only the eight 32 GB RDIMMs or are any extra parts included?

The package contains the 256 GB kit of eight 32 GB DDR5 4800 CL40 1.10 V 2Rx8 ECC RDIMMs and nothing else; no heat spreaders, cables, or tools are supplied.
