Lenovo 7X77A01305-01 64GB PC4-21300 DDR4-2666MHz Registered ECC CL19 288-Pin Load Reduced DIMM 1.2V Quad Rank Memory Module

The Lenovo 7X77A01305-01 64GB PC4-21300 DDR4-2666MHz Registered ECC CL19 288-Pin Load Reduced DIMM is a high-performance memory module designed specifically for enterprise-grade servers and data centers. Ideal for workloads requiring large memory capacities and reliable data integrity, this 64GB module supports DDR4 technology with a speed of 2666MHz. It is compatible with Lenovo server models that support DDR4 LRDIMM modules, providing enhanced system stability and efficiency for virtualization, database management, and cloud computing environments.

This memory module combines advanced features to ensure optimal performance and reliability. It operates at a low voltage of 1.2V to reduce power consumption and heat generation, while its Load Reduced DIMM (LRDIMM) architecture enables higher memory density and improved signal integrity. The module features Error-Correcting Code (ECC) technology to detect and correct memory errors, minimizing the risk of data corruption. With a quad rank (4Rx4) configuration and CAS latency of 19 (CL19), it balances speed and responsiveness for demanding applications.
