Server-grade DDR5 capacity for Supermicro

This 1.5TB kit delivers twelve 128GB DDR5 5600 registered ECC RDIMMs built for the Supermicro H14DSG-O-CPU motherboard. Each module runs at 1.1V with CL46 timing and a 2Rx4 organisation. The registered buffer lets every slot operate at full population without overloading the memory controller.

Steady throughput under full population

Registered architecture offloads electrical load from the memory controller so all twelve slots sustain rated DDR5 5600 speed continuously. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The 2Rx4 rank structure maintains signal integrity across the fully populated array.

Low-voltage operation without active cooling

Modules operate at 1.1V and ship without heat spreaders, relying on chassis airflow for thermal management. The reduced voltage lowers per-DIMM power draw compared with higher-voltage DDR5 variants. Silent, passive operation suits dense server racks where acoustic budget is constrained.

Questions about this item

How much power does the 1.10V 2Rx4 DDR5 kit draw when the Supermicro H14DSG-O-CPU runs fully populated all day?

Each 128GB module operates at 1.10V; total system draw depends on the board's memory controller and workload, so consult the motherboard manual for full-population power figures.

What motherboard slot type and population rules must the Supermicro H14DSG-O-CPU already have to accept this 12-module kit?

The board needs 12 DDR5 288-pin RDIMM slots and must support 2Rx4 registered ECC modules at DDR5-5600; verify the approved population order in the system manual before installation.

Will the registered ECC design of this DDR5-5600 kit keep older Supermicro platforms stable if I mix it with existing memory?

Mixing is not recommended; the kit is validated for the H14DSG-O-CPU with identical 2Rx4 CL46 1.10V modules in every slot to guarantee full-capacity operation and error correction.
