A-Tech 64GB DDR4 2666MHz PC4-21300 CL19 1.20V ECC LRDIMM 4Rx4 288-Pin Server RAM

Server Memory for High-Density Workloads

This 64GB DDR4 LRDIMM targets servers and workstations that require large memory footprints per slot. The quad-rank design and load-reduced architecture let a single module deliver 64GB while easing electrical load on the memory controller. It suits virtualisation hosts, database nodes and compute clusters where maximum capacity per channel is the priority.

Build Quality and Connector Implications

Supermicro certification confirms the module meets the vendor’s validated hardware list for supported platforms. The 288-pin LRDIMM form factor fits standard DDR4 server slots, while the 1.20V operating voltage aligns with DDR4 baseline power. ECC load-reduced buffering adds error correction and signal integrity for continuous operation in multi-DIMM configurations.

Practical Limits of the DDR4 Interface

DDR4 2666 (PC4-21300) bandwidth and CL19 latency define the throughput ceiling for this module. Quad-rank density can restrict maximum supported DIMMs per channel on some platforms, so total system capacity may be limited by the memory controller rather than slot count. Buyers needing higher frequencies or lower latencies must select modules rated for those specifications.
