NEMIX RAM 64GB DDR4 2666 PC4-21300 4Rx4 1.2V CL19 288-PIN ECC RDIMM memory upgrade

Micron-compatible 64 GB DDR4 module

This 64 GB DDR4 2666 registered DIMM is built for Micron-based servers and workstations that require ECC protection. The single-module design fills one 288-pin slot with a 4Rx4 organisation, delivering 64 GB of capacity at 1.2 V. It targets administrators who need to expand memory in validated OEM platforms without mixing kit configurations. Buyers who need non-ECC UDIMMs for consumer desktop boards cannot use this module.

Sustained load behaviour with registered ECC

The registered buffer and on-die ECC keep data integrity intact during continuous multi-threaded workloads such as virtualisation, database caching or large-file rendering. CL19 latency at 2666 MT/s provides deterministic timing when all ranks are active across all channels. The 4Rx4 rank structure allows the memory controller to interleave requests efficiently across the module. Systems that require higher single-thread bandwidth or lower latency than CL19 will not gain from this part.

Thermals noise and power at 1.2 V

Operating at 1.2 V without a heat spreader, the module relies on server chassis airflow for cooling. Power draw remains proportional to the 64 GB density and registered interface, staying within standard DDR4 RDIMM limits for the platform. Acoustic contribution is negligible because no active cooling is attached to the stick itself. Builds with restricted airflow or passive-only enclosures should verify case ventilation before populating every slot.
