  • Registered ECC RDIMM architecture offloads the controller and corrects single-bit errors
  • 1 V operating voltage and 2Rx8 rank exactly as the Supermicro H13SST-G requires
  • 288-pin DDR5 form factor validated for the target motherboard's population rules

Supermicro H13SST-G memory kit

This 384 GB kit contains eight 48 GB DDR5 4800 RDIMM modules built for the Supermicro H13SST-G motherboard. Registered ECC design lets the board run every slot at full capacity while correcting single-bit errors on the fly. It targets administrators who need maximum supported memory in a single validated package.

Upgrade from partial population

Replacing a partially filled board or lower-capacity RDIMMs with this full 8 x 48 GB kit removes mixed-rank bottlenecks and enables the memory controller to operate at its rated 4800 MT/s across all channels. The jump is worth it when workloads demand the full 384 GB limit and stability under sustained load.

Straightforward RDIMM installation

Modules use the standard 288-pin RDIMM form factor and 1.1 V operation, so they seat like any registered DIMM. The main risk is ignoring the motherboard manual population order; wrong slot sequence can prevent boot or limit capacity. Verify the approved sequence before fitting all eight sticks.

Questions about this item

What physical slot and module type does the Supermicro H13SST-G require for this 384GB kit?

The board takes 288-pin DDR5 RDIMM modules; this kit provides eight 48 GB registered ECC DIMMs that match that exact form factor.

What is the correct population order when installing all eight 48 GB RDIMMs on the H13SST-G?

Follow the motherboard manual's approved DIMM population sequence for full 384 GB capacity; the kit's 2Rx8 registered modules must be seated in the prescribed slots for the memory controller to initialise at 4800 MT/s.

Do these DDR5 RDIMMs need any firmware updates or battery-backed components replaced over time?

No firmware or battery maintenance is required; the modules are solid-state registered ECC DIMMs with a lifetime replacement warranty covering any future failure.
