The Samsung M386A8K40BM2-CTD is a 64GB DDR4 Load-Reduced DIMM (LRDIMM) with quad-rank (4Rx4) configuration and full ECC support, engineered for high-density server and workstation deployments. This LRDIMM architecture reduces electrical loading on the memory controller, enabling greater memory capacity per system while maintaining stability—making it ideal for storage architects and data center infrastructure teams building scalable solutions.
Built on Samsung's proven DDR4 technology, this module operates at 2666 MT/s with a 19-19-19 CAS latency, delivering consistent performance across demanding enterprise workloads. The 288-pin registered DIMM format with integrated data buffer ensures compatibility with enterprise-grade server platforms that support LRDIMMs, while low-profile design (31.25 mm) accommodates standard server form factors. Operating across 0°C to 85°C, the module meets JEDEC DDR4 standards and runs at just 1.2 V, optimizing both thermal efficiency and power consumption in multi-socket configurations.
For enterprise memory solutions, Omnixon Global stocks Samsung DDR4 LRDIMMs across multiple capacities and configurations. Contact us to request a formal quotation for the M386A8K40BM2-CTD and explore volume pricing for your infrastructure deployment.
