  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes
  • Massive 768 GB capacity from sixteen 48 GB modules
  • DDR5 6400 speed with CL52 latency for high throughput
  • Registered ECC design prevents silent data corruption
  • 1 V operation matches server memory controller spec
  • Exact fit for Supermicro H13DSH motherboard

Exact-match server kit

This 768GB kit contains 16 modules of 48GB each built as 2Rx8 registered ECC RDIMMs for DDR5 6400 systems. It targets administrators upgrading a Supermicro H13DSH motherboard that requires the precise rank, voltage and timing combination supplied here.

Thermals and power

Each module operates at 1.10V without a heat spreader, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller when all slots are populated, keeping power draw steady during sustained workloads.

Build integration

The 288-pin RDIMM form factor fits only boards wired for registered DDR5; it will not work in UDIMM or SODIMM slots. Populate all 16 slots following the motherboard manual's population order to reach the rated capacity and speed.

Questions about this item

How do I install the 16 DDR5 RDIMMs into the Supermicro H13DSH and which population order is the step most people get wrong?

Fill the 16 slots following the motherboard manual's exact population sequence; the board requires a specific order per CPU socket and skipping a step causes the system to ignore modules or run at reduced capacity.

What maintenance or replacement will the 2Rx8 registered ECC modules need during their service life?

Registered ECC DDR5 RDIMMs have no moving parts or user-serviceable components; they run until a correctable error rate rises or a module fails, at which point the single faulty 48 GB stick is replaced.

What limit appears first when all 16 modules run sustained workloads at DDR5-6400 CL52?

The memory controller's maximum supported rank count and thermal envelope are reached first; fully populating 16 dual-rank RDIMMs at 1.10 V pushes the controller to its electrical and cooling limits before bandwidth saturates.
