Certified Supermicro Server Memory

This 32GB DDR4 module carries Supermicro certification for validated compatibility with qualified platforms. It operates at 2666MHz with CL19 latency and a standard 1.2V supply. The registered ECC design supports data integrity in continuous operation.

Suited for registered ECC configurations only

Systems that require unbuffered non-ECC memory cannot use this module. Builders needing higher frequencies or lower latencies should look at other specifications. The single 32GB rank layout limits total capacity per channel on some boards.

Registered ECC with Samsung 2Rx4 chips

The module uses Samsung M393A4K40BB2-CTD components in a 2Rx4 organisation. Registered signalling and on-board ECC correct single-bit errors and reduce electrical load on the memory controller. This combination defines whether the part matches the platform requirements.

Preguntas sobre este artículo

How do I install this 288-pin RDIMM and what step is often missed?

Align the notch on the 288-pin RDIMM with the slot key, press firmly until both side clips click shut, then verify the system recognises the full 32GB capacity at 2666MHz in BIOS.

What maintenance or replacement will this 32GB ECC module need over time?

No routine maintenance is required; the module is tested for dependable operation and covered by a lifetime warranty, so replacement would only occur if a hardware fault develops.

What limit appears first when this DDR4 2666 CL19 1.2V module runs under sustained load?

The DDR4 2666 speed and CL19 latency define the throughput ceiling, while the 1.2V standard voltage sets the thermal envelope during continuous operation.
