128GB DDR5 ECC RDIMM kit for Supermicro H13SSL-NT

This 128GB kit contains four 32GB DDR5 4800 modules built to the exact rank, voltage and timing the Supermicro H13SSL-NT memory controller expects. Registered ECC architecture keeps every slot stable at full population while correcting single-bit errors before they reach production workloads. It is designed for administrators who need guaranteed compatibility and maximum capacity on this specific server board.

Check your motherboard manual for population rules

Before ordering, consult the Supermicro H13SSL-NT manual for approved DIMM population order, supported capacities per channel and any BIOS version requirements. The board requires 288-pin Registered RDIMMs; UDIMM or SODIMM modules will not fit or function. Verify that your configuration matches the 2Rx8 organisation and 1.1V operating voltage specified for this kit.

Registered design with major OEM chips

Modules use Samsung, Micron or Hynix components in a registered layout that buffers address and command signals, reducing electrical load on the memory controller when all slots are filled. No heat spreaders are fitted, so airflow across the DIMMs must be maintained by the server chassis. The 288-pin DDR5 keying prevents accidental installation in incompatible slots.

Questions about this item

Does the kit include only the four 32 GB DDR5 RDIMMs or are any cables or tools supplied?

The package contains four 32 GB DDR5 4800 CL40 1.1 V 2Rx8 288-pin ECC Registered RDIMM modules and nothing else.

Should I choose this 128 GB kit or a different capacity for the Supermicro H13SSL-NT?

This 128 GB kit matches the board's DDR5 4800 registered ECC requirement; select it when your workload needs the full 128 GB across four slots.

Will the system actually run at DDR5 4800 with CL40 once all four modules are installed?

Yes, the modules are spec-matched to the H13SSL-NT memory controller so the server recognises the full 128 GB at the rated 4800 MT/s CL40 timing.
