The LENOVO 49Y1507 Express is an 8GB memory module engineered to enhance server performance and reliability through its ECC DDR3 technology. Operating at a frequency of 1333MHz (PC3-10600) and a CAS latency of 9 (CL9), this module delivers efficient data processing and system responsiveness. The low voltage operation (1.35V) makes it more energy-efficient, reducing power consumption and heat output in data centers. Its ECC (Error Correcting Code) feature ensures that data corruption is detected and corrected in real-time, crucial for maintaining system uptime and data integrity in enterprise environments. The 2Rx4 configuration denotes a dual-rank design that can provide higher bandwidth compared to single-rank modules. With its low-profile RDIMM form factor, it is suited for servers with constrained space, offering a seamless fit without compromising performance. This LENOVO module is perfect for businesses seeking to upgrade their server capabilities with reliable and efficient memory.
