SKU CH-EHGF-WNHBK

16 GB DDR4-2666 ECC registered dual-rank DIMM with CL19 latency at 1.2 V

  • 16 GB capacity for demanding workloads
  • DDR4-2666 speed rated at PC4-21300
  • ECC registered design protects data integrity
  • Dual-rank x8 organisation at 1.2 V

16 GB DDR4-2666 ECC registered module

This 16 GB DDR4-2666 module uses ECC registered technology for error correction and signal buffering. It is built for workstations and servers that require data integrity over raw speed. The dual-rank x8 organisation supports higher densities per channel. Systems needing standard unbuffered memory cannot use this module.

Registered design and 1.2 V operation

The registered architecture reduces electrical load on the memory controller, allowing larger memory populations in compatible platforms. Operating at 1.2 V, it matches the standard DDR4 voltage for efficient power draw. CL19 latency and PC4-21300 rating define its timed performance envelope. Motherboards without registered DIMM support will not accept this memory.
