NEMIX RAM ML21300-944K1 64GB DDR4 2666 ECC LRDIMM memory upgrade

64 GB DDR4-2666 ECC LRDIMM

This NEMIX RAM module delivers 64 GB of DDR4-2666 ECC Load Reduced memory in a single 288-pin LRDIMM. It is built for servers and workstations that require registered ECC stability at 1.2 V with CL19 latency. The 4Rx4 organisation suits high-capacity motherboards designed for load-reduced DIMMs. Buyers expanding Micron-compatible platforms can use this part to increase total system memory.

Check motherboard LRDIMM support and slot population

Verify that your server or workstation motherboard accepts DDR4 Load Reduced DIMMs and supports 4Rx4 modules at 2666 MT/s. Consult the system manual for maximum capacity per slot and approved population rules, as some platforms restrict LRDIMM mixing with standard RDIMMs. Ensure the BIOS is current enough to recognise 64 GB single-rank density before installation.

Thermals noise and power in normal operation

The module runs at 1.2 V without a heat spreader, relying on chassis airflow for cooling. In typical server workloads power draw stays modest and the bare PCB adds no acoustic noise beyond the system fans. Load Reduced buffering reduces electrical loading on the memory bus, helping maintain signal integrity at full 2666 MT/s speed during sustained use.
