Exact-fit server memory kit

This 192GB kit contains two 96GB DDR5 RDIMMs built to the Supermicro H13DSG-O-CPU-D motherboard's specifications. Registered ECC modules with a 2Rx4 rank configuration ensure the memory controller recognises full capacity across every populated slot. The 288-pin form factor matches the board's DIMM sockets precisely. System administrators upgrading compatible Supermicro platforms receive a validated, ready-to-install solution.

Sustained enterprise stability

Registered architecture buffers address and command signals so the memory controller drives all slots at rated speed without signal degradation under continuous load. ECC circuitry detects and corrects single-bit errors in real time, preventing silent data corruption during long-running workloads. Modules operate at 1.10V, reducing thermal stress when the system runs fully populated for extended periods. This combination keeps production services stable through heavy, sustained utilisation.

DDR5 4800 CL40 specification

Rated at DDR5 4800 (PC5-38400) with CL40 latency, these modules deliver the exact timing the platform expects for error-free initialisation. Deviating from this speed or latency grade can cause training failures or forced downclocking. The 2Rx4 organisation and registered buffer are mandatory for this motherboard's population rules. Verify the manual's approved DIMM sequence before installation to guarantee full 192GB recognition.

Questions about this item

Does the 1.10V DDR5 4800 kit run hot or draw more power when the Supermicro H13DSG-O-CPU-D is fully loaded all day?

The modules operate at the standard DDR5 voltage of 1.10V with no heat spreader, so thermal output and power draw stay at the JEDEC baseline for 4800 CL40 registered DIMMs under sustained load.

What must the Supermicro H13DSG-O-CPU-D motherboard already provide for this 2Rx4 ECC RDIMM kit to function?

The board needs DDR5 RDIMM slots that support 2Rx4 registered ECC modules at 4800 MT/s and 1.10V, plus a memory controller able to address 96GB per DIMM in the population order the manual specifies.

Will the 288-pin registered ECC modules work in the same channels as any lower-capacity DDR5 RDIMMs I keep in the H13DSG-O-CPU-D?

Yes, provided the existing DIMMs are also DDR5 registered ECC at 1.10V; the memory controller will train all populated slots to a common speed and timing, so the 96GB modules coexist with smaller registered kits.
