Exact-match DDR5 server kit

This 256GB kit (4 x 64GB) delivers DDR5 6400 (PC5 51200) with CL52 latency at 1.10V. Registered ECC 2Rx4 RDIMM modules match the precise rank, voltage and timing the Supermicro H13DSH memory controller expects for full-capacity recognition and rated speed.

Registered architecture offloads the controller

Registered (buffered) design offloads the memory controller so every slot runs fully populated at full capacity while ECC catches and corrects single-bit errors on the fly. Low 1.10V operation and the absence of a heat spreader keep power draw and thermals modest in normal server workloads.

Requires DDR5 RDIMM slots and manual check

The 288-pin RDIMM form factor fits only DDR5 RDIMM slots — not UDIMM or SODIMM. Builders must consult the Supermicro H13DSH manual for supported capacities, approved DIMM population order and installation steps before purchase. No other motherboard or processor compatibility is implied.

Questions sur cet article

How do I install the four 64GB DDR5 RDIMMs in the Supermicro H13DSH and which population order is the one people get wrong?

Install all four modules in the exact slot sequence shown in the H13DSH manual; the common mistake is skipping the prescribed population order, which prevents the board from recognising the full 256GB at DDR5-6400.

Will the Samsung Micron or Hynix chips on these ECC RDIMMs need any firmware updates or scheduled replacement?

No firmware updates or scheduled chip replacements are required; the on-die ECC and registered architecture handle error correction for the module's lifetime.

At what point does the 1.1V CL52 timing become the limiting factor during sustained server workloads?

The CL52 latency at 1.1V is the first timing ceiling you hit under continuous load; registered buffering keeps all four ranks stable at DDR5-6400 without further throttling.
