Supermicro H13SSW DDR5 upgrade

This 16 GB DDR5 4800 registered ECC RDIMM is built to the exact rank, voltage and timing the Supermicro H13SSW motherboard expects. It installs as a single 288-pin module so the server recognises full capacity at rated speed.

Replacing slower or smaller DDR5 DIMMs

Swapping older DDR5 modules for this CL40 1.10 V part adds 16 GB per slot while keeping registered buffering and ECC active across every populated channel. The jump is worth it when your workload needs maximum registered-DIMM capacity without mixing ranks or voltages.

DDR5 registered DIMM limits

DDR5 RDIMMs require a motherboard that supports registered signalling and the correct population order; UDIMM or SODIMM slots will not accept the 288-pin form factor. Always verify the system manual for approved capacities and slot sequence before installation.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the Supermicro H13SSW motherboard slots?

Yes, the module is a 288-pin DDR5 RDIMM, which matches the form factor and registered architecture required by the H13SSW motherboard.

What is the correct installation step for the 1Rx8 registered ECC module on this board?

Power down the server, open the chassis, align the module's key notch with the DDR5 slot, press firmly until the ejector clips lock, then follow the motherboard manual's population order for registered DIMMs.

Will the 1.1V DDR5 module require any firmware update or replacement over time?

The module operates at the standard 1.1V DDR5 voltage with ECC error correction; no firmware updates are needed, and it is covered by a lifetime replacement warranty if a hardware fault occurs.
