The LENOVO 46W0735 is a 4GB DDR3 memory module optimized for ECC (Error Correction Code) compatibility, designed to enhance the memory capacity and performance of certain Lenovo servers and workstations. Operating at a lower voltage of 1.35V compared to standard DDR3 modules (which typically require 1.5V), it offers a more energy-efficient solution, helping to reduce the overall power consumption of the system it's installed in. The PC3L-12800 specification indicates a theoretical peak data transfer rate of 12800MB/s, making this module well-suited for applications that benefit from fast data access. With a CAS latency of 11 (CL11), it achieves a balance between speed and timing accuracy, contributing to the system's overall responsiveness and stability. The ECC capability further ensures data integrity, an essential feature for professional and enterprise environments where data accuracy is critical. The 2Rx8 configuration indicates a dual-rank setup with eight banks, enhancing the module's compatibility and performance reliability in supported systems.
