A-Tech 64GB DDR4 2666MHz ECC LRDIMM 4Rx4 Server Memory

64GB DDR4 LRDIMM for Servers

This 64GB DDR4 2666MHz ECC LRDIMM module is built for server and workstation platforms that require registered, load-reduced memory. It delivers 64GB of capacity in a single 288-pin DIMM running at 1.2V with CL19 latency. The 4Rx4 rank organisation suits high-density configurations where maximum memory per slot is needed.

Load-Reduced ECC with 4Rx4 Rank

The defining specification is the Load-Reduced DIMM architecture combined with ECC and a 4Rx4 rank structure. This combination reduces electrical load on the memory controller, allowing larger memory footprints than standard RDIMMs while maintaining error correction for data integrity. Systems that specify LRDIMM 4Rx4 modules at DDR4 2666 will accept this part.

Steady Throughput Under Sustained Load

Operating at the standard DDR4 voltage of 1.2V, the module maintains its rated 2666MHz speed during extended workloads typical of virtualisation, database or compute clusters. ECC circuitry continuously corrects single-bit errors without halting the system, so throughput remains consistent rather than degrading when background error rates rise. The load-reduced design keeps signal integrity stable across all ranks during prolonged, multi-threaded operation.
