Capacity and fit

This 1.5 TB kit contains twelve 128 GB DDR5 RDIMMs built for the Supermicro H13DSG-OM motherboard. Registered ECC modules with 2Rx4 organisation and CL40 timing match the board's memory controller requirements exactly. The kit is intended for administrators who need maximum supported capacity in a single validated package.

Build integration

Each 288-pin RDIMM installs directly into the server's DDR5 slots without adapters or converters. Registered buffering reduces electrical load on the memory controller so all twelve slots can be populated at the rated 4800 MT/s speed. ECC circuitry corrects single-bit errors automatically, protecting data integrity in production workloads.

Thermals and power

Modules operate at the standard DDR5 voltage of 1.1 V and ship without heat spreaders, relying on the chassis airflow designed for the H13DSG-OM platform. Registered architecture keeps per-module power draw consistent even with every slot filled. The combination of low voltage and server-directed cooling maintains stable temperatures under sustained load.

  • DDR5 4800 speed with CL40 latency for rated throughput
  • Registered ECC design corrects single-bit errors automatically
  • 1 V operation matches server memory controller specs
  • Verified fit for Supermicro H13DSG-OM motherboard

Questions about this item

What sustained-use limit appears first when all 12 slots are populated on the Supermicro H13DSG-OM?

The registered ECC architecture lets every slot run fully populated at the rated 1.5 TB capacity without down-clocking, so the first limit is the motherboard's maximum supported memory.

How much power and heat does the 12-module kit add when the server runs 24/7?

Each 128 GB DDR5 RDIMM operates at 1.1 V, so the complete kit draws roughly 12 × 1.1 V × rated current, producing modest heat that the server's existing airflow handles without extra cooling.

What must the buyer already own for this 1.5 TB kit to function?

A Supermicro H13DSG-OM motherboard with all 12 DDR5 RDIMM slots free, a compatible CPU that supports 2Rx4 registered ECC memory, and the board manual to confirm population order.
