The LENOVO 49Y3711 module is a 1GB DDR3 memory designed to enhance the performance of select Lenovo servers. Operating at PC3-10600 speeds (1333MHz) and with a CAS Latency of 9, it ensures timely access to memory for processes, thereby improving the system's throughput. The module's ECC (Error-Correcting Code) capability detects and corrects data corruption, providing a significant reliability advantage in server environments where data integrity is paramount. This 1GB module, while modest in capacity, is aimed at environments with specific memory requirements or servers needing a slight bump in memory without a complete overhaul. Its ECC feature, paired with DDR3 technology, offering a balance between performance, power efficiency, and reliability, making it an optimal choice for older Lenovo servers requiring a memory refresh.
