Show 24 more configurations
  • 64 GB total capacity from four 16 GB modules for full server population
  • DDR5 4800 speed with CL40 latency matches the board's rated memory controller timing
  • Registered ECC RDIMM design offloads the controller and corrects single-bit errors on the fly
  • 1 V operation reduces power draw across all four slots at full load
  • Verified 288-pin fitment for Supermicro H13SSL-N motherboard memory population rules

Exact-match 64 GB DDR5-4800 kit

This 64 GB kit contains four 16 GB DDR5 4800 RDIMMs built to the Supermicro H13SSL-N memory controller's rank, voltage and timing requirements. Registered ECC operation with CL40 latency at 1.1 V lets the board recognise full capacity and run at rated speed without manual tuning.

Installation requires registered DIMM slots

The modules use the 288-pin RDIMM form factor this motherboard requires, not UDIMM or SODIMM. Population order and maximum supported capacity vary by board revision, so the system manual must be consulted before inserting modules to avoid unrecognised slots or reduced speeds.

DDR5-4800 bandwidth ceiling

The PC5-38400 interface caps theoretical throughput at the DDR5-4800 data rate, limiting peak bandwidth regardless of how many channels the CPU provides. Registered buffering and ECC add latency overhead that cannot be removed, so workloads needing lower latency or higher raw bandwidth will hit this standard's hard ceiling.

Questions about this item

How do I verify the kit runs at DDR5 4800 CL40 after installing it in my Supermicro H13SSL-N?

Enter the BIOS or UEFI and confirm the memory frequency shows 4800 MT/s with CL40 timings and 1.10 V; the registered ECC modules will also report corrected error counts as zero during POST.

What comes in the package and do I need anything else to populate the board?

The box contains the 64 GB kit as four 16 GB 288-pin RDIMMs; no extra brackets, cables or cooling are required — just install them in the slots specified by the motherboard manual.

Should I choose this 4 x 16 GB kit or a different capacity for the H13SSL-N?

This 64 GB kit (4 x 16 GB, 1Rx8, 1.1 V, CL40) matches the board's validated population rules for full-speed operation; select a different kit only if your manual lists another approved capacity or rank configuration.
