Server-grade DDR4 module

This 64 GB DDR4-2666 registered ECC DIMM is built for servers and workstations that require error-correcting memory. The 2Rx4 organisation and CL19 latency support high-density configurations in multi-socket platforms.

Sustained-load behaviour

Top-tier DRAM chips from Samsung, SK Hynix or Micron are used to maintain stable throughput during extended workloads. Rigorous validation reduces the likelihood of correctable errors accumulating under continuous memory pressure.

Upgrade context

It replaces smaller registered DIMMs when a system needs more capacity per slot for virtualisation or in-memory databases. The jump is worthwhile only when the platform supports DDR4-2666 registered memory and the application benefits from the additional 64 GB per module.
