Capacity & fit

This is a 512 GB kit of four 128 GB DDR5 registered ECC RDIMMs built to the exact specification of the Supermicro H13SSL-NT motherboard. It targets administrators who need the full supported capacity in a single validated package.

Upgrade path

It replaces partial populations or slower DDR5 kits that leave slots empty or run below the board's rated 5600 MT/s speed. The jump is worth it when the workload demands the maximum registered DIMM capacity the platform allows.

Build integration

The modules use the 288-pin RDIMM form factor and 1.1 V operation the board requires, with 2Rx4 organisation and CL46 timing that the memory controller expects at full population. They free the installer from mixing ranks or voltages that would prevent the system from recognising the full 512 GB.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the Supermicro H13SSL-NT motherboard slots?

Yes, the 288-pin Registered DIMM form factor matches the slots on the Supermicro H13SSL-NT. The kit provides four 128 GB modules for a total of 512 GB.

What is the correct population order when installing all four modules on the H13SSL-NT?

Install the modules in the sequence specified by the Supermicro H13SSL-NT manual. The board requires a specific DIMM population order for full 512 GB recognition at DDR5-5600.

Do these 1.1 V DDR5 modules need any firmware updates or battery replacements over time?

No firmware updates or battery replacements are required for the memory modules themselves. They operate at 1.1 V with CL46 timing and ECC correction for the life of the server.
