NEMIX RAM 64GB DDR4 2666 PC4-21300 4Rx4 1.2V 288-Pin ECC LRDIMM Server Memory

Server-grade capacity for virtualization

This 64 GB DDR4 LRDIMM module targets administrators who need large memory pools for virtualized workloads on compatible QNAP NAS platforms. The load-reduced design places less electrical load on the memory bus, allowing higher total capacities per channel. It operates at 2666 MT/s with a CAS latency of 19 and runs at 1.20 V. ECC protection corrects single-bit errors to preserve data integrity in mission-critical environments.

Fits QNAP NAS bays with DDR4 LRDIMM slots

Installation requires an available 288-pin DDR4 LRDIMM socket on a supported QNAP motherboard; the module is validated against the RAM-64GDR4ECS0-LR-2666 reference. Because it is a load-reduced DIMM, it frees electrical headroom for additional modules in multi-slot configurations. The 4Rx4 organization delivers the 64 GB density in a single stick, reducing slot consumption. No heat spreader is fitted, so airflow across the PCB must be provided by the chassis.

Low-voltage operation limits thermal output

At 1.20 V the module draws modest power under typical server loads, keeping case temperatures manageable in densely populated NAS enclosures. Passive cooling relies on system airflow rather than an integrated spreader, so fan speed curves should ensure air moves across the memory region. The registered buffer and ECC logic add minimal latency while maintaining signal integrity at 2666 MT/s. Acoustic contribution is negligible compared with drive and chassis fans.
