Speed 4800MHz

  • 128 GB total capacity across four 32 GB modules
  • DDR5 4800 speed with CL40 latency for rated server performance
  • Registered ECC architecture offloads the controller and corrects single-bit errors
  • 1 V operation matches the platform's voltage specification
  • 288-pin RDIMM form factor verified for Supermicro H13SRH motherboard

Exact-match DDR5 kit for Supermicro H13SRH

This 128 GB kit contains four 32 GB DDR5 4800 RDIMMs built to the precise rank, voltage and timing the Supermicro H13SRH memory controller expects. Each module is a 288-pin registered ECC DIMM rated at CL40 and 1.10 V, so the board recognises the full capacity at its rated speed without manual tuning.

Enterprise stability under sustained load

Registered buffering offloads the memory controller, allowing every slot to run fully populated at full capacity while ECC corrects single-bit errors on the fly. The low 1.10 V operating voltage keeps power draw modest during continuous server workloads, and the modules ship without heat spreaders for standard airflow cooling.

Upgrade from smaller or slower DDR5 RDIMMs

The jump is worth it when your H13SRH system needs the maximum supported capacity in a validated 4x32 GB configuration, replacing partial kits or lower-speed modules that limit throughput. It is not for builds that require UDIMM or SODIMM form factors, or for boards that do not support registered ECC DDR5.

Questions about this item

How do I install the 288-pin RDIMM kit in the Supermicro H13SRH, and which slot order is commonly missed?

Power down, open the chassis, and insert each 32 GB module into the slots listed first in the motherboard manual — typically the farthest slot from the CPU on each channel — then press until both latches click; skipping the prescribed population sequence is the step most often missed.

What maintenance or replacement will the 128 GB DDR5 ECC registered kit need over its service life?

The modules have no heat spreaders and no moving parts, so no routine maintenance is required; replacement is only necessary if a DIMM fails, at which point the lifetime replacement warranty covers a direct swap.

What limit appears first when the 4800 MT/s registered memory runs fully populated under sustained load?

The memory controller’s maximum supported capacity and rank-per-channel ceiling for the H13SRH is reached before thermal or voltage headroom becomes an issue, capping further expansion.
