Server-Specific DDR5 Memory Kit

This 768 GB kit consists of six 128 GB DDR5-5600 registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H13DSG-OM memory controller expects. It is intended for administrators who need maximum supported capacity in that specific platform without manual tuning.

Registered ECC Architecture for Full Population

The registered design offloads the memory controller so every slot can run fully populated at the rated 5600 MT/s speed, while on-die ECC corrects single-bit errors before they reach the operating system. The 288-pin RDIMM form factor matches the board's physical and electrical requirements; UDIMM or SODIMM modules will not fit or function.

Sustained Enterprise Stability

Operating at 1.1 V with CL46 latency, the modules maintain their specified throughput under continuous multi-socket workloads rather than only in short bursts. ECC protection remains active throughout, preventing silent data corruption during extended compute or virtualization tasks.

Questions about this item

Does the 1.10V voltage limit headroom when all six 128GB modules run at DDR5-5600 continuously?

The kit operates at the standard DDR5 1.10V. Registered buffering reduces electrical load on the memory controller, allowing full 768GB population at rated speed without exceeding the platform's voltage envelope.

What thermal and acoustic impact should I expect from a fully populated 768GB kit running 24/7 in the H13DSG-OM?

Modules have no heat spreaders; they rely on the server's forced airflow. Power draw at 1.10V across six 2Rx4 RDIMMs is moderate, so chassis fans typically stay at idle RPM, keeping noise low.

Must the Supermicro H13DSG-OM already have a specific BIOS revision or CPU stepping to recognise all 768GB at 5600 MT/s?

The board's memory controller and qualified-vendor list determine supported capacities and speeds. Consult the H13DSG-OM manual for the required BIOS version and approved DIMM population order before installing this kit.
