Supermicro Certified 8GB DDR4 RDIMM

This 8GB DDR4 2933MHz ECC Registered DIMM carries Supermicro certification and uses Micron chips for server and workstation platforms. The 288-pin module operates at 1.2V with CL21 latency and a single-rank 1Rx8 organisation. It suits administrators who need validated memory for Supermicro systems.

Factory testing and lifetime warranty

Every module undergoes quality assurance testing before shipment to confirm reliable operation in certified configurations. A-Tech backs the memory with a lifetime warranty and provides US-based technical support for installation and troubleshooting questions.

DDR4 2933 registered ECC limits

The registered buffer and ECC circuitry add one clock cycle of latency compared with unbuffered non-ECC DIMMs, which affects timing-sensitive workloads. Maximum capacity per channel depends on the memory controller and BIOS revision of the target platform. This module does not function in consumer desktop boards that lack registered DIMM support.

Questions about this item

Will the registered ECC RDIMM need any firmware updates or periodic reseating over its service life?

No firmware updates or scheduled reseating are required; the module is validated at 1.20 V and CL21 for continuous server operation.

What thermal or power limit appears first when the DIMM runs at 2933 MT/s under sustained load?

The 1.20 V DDR4 standard voltage and registered buffer keep power draw within JEDEC limits, so thermal throttling is not expected in normal airflow.

How much heat and noise does the 288-pin RDIMM add when the server runs all day?

The module itself has no moving parts and draws only 1.20 V, adding negligible heat and zero acoustic noise to the chassis.
