192GB DDR5-6400 ECC RDIMM kit

This 192GB kit delivers two 96GB DDR5-6400 registered ECC modules built to the PC5-51200 standard. The 2Rx4 organisation, 1.10V operating voltage and CL52 latency match the exact electrical profile the Supermicro H13SRH memory controller expects. It is intended for administrators who need maximum supported capacity on this platform without guesswork.

Registered 288-pin form factor for full population

Each module uses the 288-pin RDIMM form factor required by the H13SRH, not UDIMM or SODIMM alternatives. Registered buffering offloads the on-board memory controller so every slot can be populated at the rated 6400 MT/s speed. ECC circuitry corrects single-bit errors in flight, protecting data integrity on continuously running workloads.

Sustained throughput with enterprise stability

The registered architecture maintains signal quality across all populated channels during extended operation, avoiding the timing drift that can appear under continuous load. On-die ECC correction prevents silent corruption from accumulating over long uptimes. Major OEM DRAM from Samsung, Micron or Hynix underpins consistent behaviour in 24/7 server deployments.

Questions about this item

Does the 1.10V operating voltage stay within the Supermicro H13SRH memory-controller limits under sustained load?

Yes — the kit runs at the standard DDR5 1.10V, which matches the voltage the H13SRH memory controller expects for registered DIMMs.

How much heat do the two 96GB modules generate when the server runs all day without a heat spreader?

Registered DDR5 at 1.10V and CL52 typically stays cool enough for passive airflow in a server chassis; no heat spreader is fitted.

Must the Supermicro H13SRH motherboard already support 2Rx4 registered ECC DDR5-6400 to use this 192GB kit?

Yes — the board needs to accept 288-pin RDIMMs at DDR5-6400 with 2Rx4 organization and ECC for the kit to be recognized at full capacity.
