  • 2 GB capacity fits targeted memory configurations
  • Hynix manufacturing ensures component quality and compatibility

Server Memory Module

This Hynix DDR4 module delivers 2 GB of registered ECC memory for enterprise server platforms. The registered design reduces electrical load on the memory controller, allowing larger memory populations in multi-socket systems. It targets IT professionals who maintain or upgrade qualified server hardware.

DDR4-2666 Registered ECC Specification

The module operates at a 2666 MT/s data rate with error-correcting code and registered signalling. These three attributes together determine whether the part is compatible with a given server platform. Buyers must verify that their system requires DDR4-2666 registered ECC DIMMs before purchasing.

Sustained Load Behaviour

Registered ECC construction maintains data integrity during continuous workloads by correcting single-bit errors on the fly. The reduced electrical loading per module helps preserve signal quality when many DIMMs are populated and run at full throughput for extended periods. Buyers who need non-ECC or unbuffered memory for desktop platforms cannot use this module.
