Replacement DDR4 2666 ECC RDIMM

This 8 GB registered DIMM replaces the Samsung M393A1G40EB2-CTD module in compatible server and workstation platforms. It operates at 2666 MHz with a CL19 latency and standard 1.20 V DDR4 voltage. The single-rank 1Rx4 organisation uses major-brand chips on a 288-pin form factor.

Registered ECC with major-brand chips

Error-correcting code and registered buffering protect data integrity and reduce electrical load on the memory controller, allowing larger configurations in multi-socket systems. Major-brand components and per-module validation aim to deliver consistent reliability under sustained workloads.

Suits DDR4 servers needing ECC RDIMM

This module fits systems that require DDR4 2666 registered ECC memory in an 8 GB capacity. Builders needing non-ECC unbuffered DIMMs, higher frequencies, larger single-module capacities, or different DDR generations should select alternative memory.

Questions about this item

Will the registered ECC DIMM need firmware updates or periodic re-seating during its service life?

The module ships as a standard 288-pin DDR4 RDIMM with 1.20 V operation; no firmware updates or scheduled re-seating are required beyond normal server maintenance.

What limits sustained throughput on this 2666 MHz CL19 module under continuous load?

The CL19 latency at 2666 MHz and the single 1Rx4 rank set the practical bandwidth ceiling during prolonged workloads.

How much heat and power does the 8 GB registered DIMM produce when running all day?

At the standard 1.2 V DDR4 voltage the module draws minimal power and generates low heat, suitable for dense server configurations.
