A-Tech 128GB (2x64GB) DDR4 2666 ECC LRDIMM 4Rx4 Server RAM

128GB DDR4 ECC LRDIMM kit

This 128GB kit contains two 64GB DDR4 2666 ECC load-reduced DIMMs built for servers and workstations that require registered memory. The quad-rank x4 organisation lets each module address more rows per channel, raising total capacity without adding slots. Desktop and laptop platforms cannot use these modules because they lack the necessary memory controller support.

Sustained throughput with quad-rank density

At 2666 MT/s and CL19 the pair delivers PC4-21300 bandwidth continuously, while the load-reduced buffer reduces electrical load on the memory controller during long-running workloads. ECC corrects single-bit errors on the fly, preventing silent data corruption in databases, virtualisation hosts and compute clusters. The 1.20V operating voltage keeps power draw predictable under constant utilisation.

288-pin DIMMs validated for multi-channel servers

Each module uses major-brand chips on a 288-pin PCB and ships as a matched dual-channel kit to simplify population rules. A-Tech tests every stick before it leaves the factory, and the lifetime warranty covers the kit for as long as you own it. US-based technical support is available for installation guidance or compatibility questions.
