Supermicro H13SSL-N 64 GB DDR5 upgrade

This NEMIX RAM module delivers 64 GB of DDR5 4800 memory in a 288-pin RDIMM form factor. It operates at 1.1 V with CL40 latency and uses a 2Rx4 registered ECC design. The stick is built as an exact-match upgrade for the Supermicro H13SSL-N motherboard.

Suited for registered ECC servers.

This module fits servers that require registered ECC RDIMMs with 2Rx4 organisation and 1.1 V operation. It will not work in systems that only accept unbuffered UDIMMs, SODIMMs, or non-ECC memory. Builders needing a different rank layout or voltage should verify their board's qualified vendor list first.

2Rx4 registered ECC at 1.1 V decides compatibility

The single specification that determines fit is the 2Rx4 registered ECC organisation running at 1.1 V. The Supermicro H13SSL-N memory controller expects this exact rank, buffering, and voltage combination to initialise at full 64 GB capacity and 4800 MT/s speed.

Questions about this item

Does my Supermicro H13SSL-N motherboard need a specific DIMM population order for this 64GB 2Rx4 DDR5 4800 RDIMM?

Yes, the motherboard manual defines the supported capacities and approved DIMM population order. Follow that guide so the memory controller recognises the module at full capacity and rated speed.

Can I add this 2Rx4 Registered ECC DDR5 RDIMM to a server that already has 1Rx8 or 2Rx8 DDR5 RDIMMs installed?

Mixing different rank organisations is not recommended. The board's memory controller expects uniform rank and voltage across all populated slots for stable operation at 4800 MT/s.

How do I verify the module is running at 4800 MT/s with CL40 timings and ECC active after installation?

Check the BIOS memory information screen or use a tool such as dmidecode to confirm speed, CAS latency, voltage and ECC status match the rated 4800 MT/s, CL40, 1.1 V and Registered ECC configuration.
