Speed 5600MHz

  • 256 GB capacity from two 128 GB modules enables full server population
  • DDR5 5600 speed with CL46 timing delivers rated bandwidth at 1.1 V
  • Registered ECC RDIMM design corrects single-bit errors and stabilises fully loaded slots
  • 288-pin form factor matches the Supermicro H13SRH motherboard memory slots exactly
  • Major OEM Samsung Micron Hynix chips provide enterprise-grade component reliability

Server-ready DDR5 ECC kit

This 256 GB kit delivers two 128 GB DDR5 5600 RDIMM modules built for the Supermicro H13SRH motherboard. Registered ECC architecture lets the board run every slot at full capacity while correcting single-bit errors before they affect production workloads.

Thermals and power

Operating at 1.1 V the modules draw minimal power and run without heat spreaders, relying on the server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller so fully populated configurations stay stable under sustained load.

Exact specification match

The kit matches the board's required 288-pin RDIMM form factor, 2Rx4 rank structure, CL46 timing and 1.1 V voltage so the memory controller recognises the full 256 GB at rated speed. Buyers needing a different capacity, rank layout or UDIMM form factor should look elsewhere.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules on the Supermicro H13SRH and what population order should I follow?

Power down the server, open the chassis, and seat each 128 GB module in the slots specified by the Supermicro H13SRH manual; the board requires registered DIMMs in a defined population sequence so the memory controller recognises the full 256 GB at DDR5-5600.

What maintenance or replacement will the DDR5 ECC RDIMM kit need over its service life?

The modules have no heat spreaders and no moving parts, so routine maintenance is limited to keeping server airflow clean; ECC corrects single-bit errors on the fly, and the lifetime replacement warranty covers any module that fails.

What is the first limit that appears under sustained load with these CL46 1.1 V registered DIMMs?

The registered buffer and ECC logic add latency at CL46, so the memory controller’s command queue typically saturates before thermal or voltage limits are reached during continuous heavy workloads.
