16GB DDR4 3200 ECC RDIMM for Supermicro EPYC systems

This 16GB DDR4 3200 registered DIMM adds error-correcting memory to Supermicro H12SSW-iN motherboards built for AMD EPYC processors. The module runs at PC4-25600 with CL22 latency and a single 1Rx4 rank. IT teams specify it when workloads demand data integrity and registered buffering.

Thermals noise and power draw

Operating at 1.20V, the module draws low power and produces minimal heat without a heat spreader. Passive cooling in a server chassis keeps temperatures stable during continuous load. Registered signalling reduces electrical load on the memory controller, helping system fans stay quiet.

Single module packaging and validation

The package contains one 288-pin RDIMM tested under load for compatibility with the target Supermicro platform. No extra cables, software or heat spreaders are included. The validated part number MR25600-614K1 ensures the module meets the motherboard’s qualified vendor list.

Questions about this item

How do I install this 288-pin DDR4 RDIMM in the Supermicro H12SSW-iN, and which step is often missed?

Power down the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that the 16GB 1Rx4 module is recognised at 3200 MT/s with ECC active.

What maintenance or replacement will this registered ECC module need over its service life?

No scheduled maintenance is required; the module has no heat spreader and runs at 1.20 V, so keep the server fans and air filters clean to maintain airflow, and replace only if memory diagnostics report uncorrectable errors.

What limit appears first when this CL22 3200 MT/s RDIMM runs under sustained load?

The CAS latency of 22 cycles at 3200 MT/s sets the timing floor; under continuous heavy workloads the memory controller will hit this latency ceiling before bandwidth or voltage limits become a factor.
