The LENOVO 49Y1404 is a 4GB DDR3 memory module specifically designed to enhance the performance and reliability of Lenovo server systems. Operating at 1333MHz (PC3L-10600), this module provides a swift data transfer rate that facilities efficient system operations. The module adheres to CL9 (CAS Latency 9), balancing performance and latency to deliver responsive system feedback. It is configured with a dual rank (2Rx8) setup, which can offer higher data bandwidth compared to single-ranked modules in supported systems. Operating at a low voltage of 1.35V, this memory module is geared towards reducing power consumption, thereby lowering operational costs and supporting environment-friendly computing environments. The inclusion of ECC (Error-Correcting Code) technology is critical for server environments, mitigating data corruption by automatically detecting and correcting memory errors, which is essential for mission-critical applications that demand high levels of data integrity.
