128 GB DDR5 RDIMM for Supermicro H13SSL-NT

This 128 GB DDR5 4800 RDIMM is a server-grade memory upgrade built to the exact rank, voltage and timing the Supermicro H13SSL-NT motherboard expects. It uses a 288-pin registered ECC design with CL40 latency and 1.1 V operation so the system recognises the full capacity and runs at its rated speed without manual tuning.

Suited for administrators populating approved

IT teams expanding memory in a validated Supermicro H13SSL-NT configuration will find the registered architecture and ECC protection match the board's population rules. Buyers who need a different capacity, a non-ECC module, a UDIMM or SODIMM form factor, or a speed grade other than DDR5 4800 should look at other parts.

Registered ECC with 2Rx4 organisation decides fit

The single specification that determines compatibility is the 2Rx4 registered ECC organisation combined with 1.1 V DDR5 4800 timing; only modules matching this exact profile will be accepted by the H13SSL-NT memory controller at full capacity and rated frequency.

Questions about this item

Will the 288-pin DDR5 RDIMM fit the Supermicro H13SSL-NT DIMM slots?

Yes, the module uses the exact 288-pin Registered DDR5 form factor required by the H13SSL-NT, so it seats directly in the board's DDR5 RDIMM slots without adapters.

What is the correct installation order when populating all channels on the H13SSL-NT?

Follow the motherboard manual's population sequence — typically fill the primary slot of each channel first, then add the second slot per channel, ensuring the 2Rx4 registered DIMMs are installed in the approved order for full 128GB recognition.

Does the 1.1V DDR5 RDIMM require any firmware update or ongoing maintenance on the H13SSL-NT?

No scheduled maintenance is needed; the module runs at the standard 1.1V DDR5 voltage and relies on the board's memory controller for ECC scrubbing, so only a BIOS update per Supermicro's release notes may improve compatibility.
