Purpose-built server memory

This 2 TB kit contains 16 modules of 128 GB each, built to the DDR5 6400 (PC5-51200) standard with CL52 latency and 1.1 V operation. The 288-pin registered ECC RDIMM form factor is exactly what the Supermicro H13DSG-OM motherboard requires for full-capacity recognition.

Registered architecture and ECC

Registered buffering offloads the memory controller so all 16 slots can run fully populated at rated speed, while on-die ECC corrects single-bit errors before they reach the operating system. The 2Rx4 organisation matches the board's population rules without needing additional configuration.

DDR5 6400 CL52 at 1.1 V

The memory controller expects this precise speed, latency and voltage combination; any deviation prevents the kit from initialising at its rated 6400 MT/s. Buyers whose platforms require a different data rate or voltage must select an alternative kit.

Questions about this item

Will the 16x128GB DDR5 6400 CL52 1.1V 2Rx4 ECC RDIMM modules need replacement if the server runs continuously?

The modules have no heat spreader and rely on chassis airflow; with adequate cooling they are rated for continuous operation and carry a lifetime replacement warranty.

What limit appears first when all sixteen slots are populated at DDR5-6400 on the Supermicro H13DSG-OM?

The registered 2Rx4 architecture offloads the memory controller so every slot runs fully populated at the rated 6400 MT/s without down-clocking.

How much heat and power does the 2TB kit draw when the system runs all day?

Each module operates at 1.10 V; total power scales with the 16 x 128 GB population, and the lack of heat spreaders means chassis airflow must handle the thermal load.
