  • 256 GB kit lets you fully populate eight slots with 32 GB modules
  • DDR5-4800 speed and CL40 latency match the motherboard's rated specifications
  • Registered ECC design corrects single-bit errors and offloads the memory controller
  • 10 V operation meets the platform's standard DDR5 voltage requirement
  • Validated for the Supermicro H13SSL-N motherboard with 288-pin RDIMM form factor

Targeted Supermicro H13SSL-N memory upgrade

This 256 GB kit delivers eight 32 GB DDR5 RDIMMs built to the exact rank, voltage and timing the Supermicro H13SSL-N memory controller expects. Registered ECC architecture offloads the controller and corrects single-bit errors so fully populated slots run stably at the rated 4800 MT/s.

Not for non-registered or consumer platforms

Systems that require unbuffered UDIMMs, SODIMMs or non-ECC memory cannot use these registered modules. Buyers needing lower total capacity or a different DIMM population layout should verify their motherboard manual before purchasing.

DDR5 4800 CL40 1.1 V registered ECC specification

The modules operate at DDR5 4800 (PC5-38400) with CL40 latency at 1.10 V in a 2Rx8 registered configuration. This precise combination of speed, timing, voltage and registered ECC function is the single factor that determines whether the kit will be recognised at full capacity and run without errors on the target Supermicro motherboard.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the DIMM slots on my Supermicro H13SSL-N motherboard?

Yes. The kit uses the 288-pin Registered DDR5 form factor that the H13SSL-N requires; it is not a UDIMM or SODIMM, so it matches the board's physical slot keying and population rules.

What is the correct installation order for the eight 32 GB modules on the H13SSL-N?

Populate the DIMM slots in the sequence specified in the Supermicro H13SSL-N manual — typically one module per channel first, then fill remaining slots — so the memory controller recognises all 256 GB at the rated DDR5-4800 speed.

Do these registered ECC modules need any firmware updates or periodic reconfiguration during their service life?

No. The DDR5 RDIMMs operate at the fixed 1.1 V, CL40, 2Rx8 specification; once seated and recognised by the BIOS they require no firmware flashes, timing changes or scheduled maintenance.
