  • 384 GB total capacity from four 96 GB modules for maximum server memory density
  • DDR5 4800 speed with CL40 latency matching the motherboard's rated specification
  • Registered ECC RDIMM architecture corrects single-bit errors and stabilises fully populated slots
  • 10 V operating voltage and 2Rx4 rank align with the Supermicro H14DSG-OD memory controller
  • 288-pin DDR5 RDIMM form factor fits the exact DIMM slots required by the board

Capacity and compatibility

This 384GB kit contains four 96GB DDR5 4800 CL40 ECC Registered RDIMMs built for the Supermicro H14DSG-OD motherboard. The 2Rx4 rank and 1.1V voltage match the board's memory controller so every slot is recognised at full capacity and rated speed. Server administrators who need maximum registered memory in this platform use this kit.

Upgrade path and population rules

The kit replaces any smaller-capacity RDIMM set or partially populated configuration that leaves slots empty on the H14DSG-OD. The jump is worth it when workloads demand the full 384GB at DDR5 4800 and the manual confirms the approved population order for four 2Rx4 modules. Builders using UDIMMs or SODIMMs cannot use this product.

Build integration

Each module is a 288-pin Registered DIMM without a heat spreader, so it fits the standard server DIMM sockets on the H14DSG-OD. Registered buffering offloads the memory controller, allowing all four slots to run fully populated while ECC corrects single-bit errors on the fly. Consult the motherboard manual for exact installation steps and supported capacity limits before installation.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the Supermicro H14DSG-OD motherboard slots?

Yes, the 288-pin RDIMM form factor matches the slots on the Supermicro H14DSG-OD motherboard; the kit is spec-matched to the board's memory population rules for full recognition.

What is the correct installation sequence for the four 96GB modules on this board?

Consult the Supermicro H14DSG-OD manual for the approved DIMM population order; installing the 2Rx4 registered modules in the wrong slots can prevent the system from booting or recognizing the full 384GB capacity.

Does the registered ECC design reduce the need for future firmware updates or module replacement?

The registered architecture and on-die ECC correct single-bit errors in real time, improving long-term stability, but firmware updates from Supermicro may still be required for optimal compatibility and performance over the server's lifecycle.
