The LENOVO 49Y1440 is a low-profile (VLP) Registered DIMM (RDIMM) memory module, providing 4GB of DDR3 memory to enhance server performance. Designed specifically for environments where space is at a premium, its very low profile form factor makes it an ideal choice for blade servers, networking equipment, and other space-constrained systems. This memory module operates at a voltage of 1.5V and utilizes PC3-10600 technology, capable of reaching speeds up to 1333MHz. Such specifications ensure it provides a balanced combination of performance and power efficiency, making it well-suited for a variety of server applications, including those that require high memory bandwidth. The 2Rx4 configuration signifies a dual-rank module, offering improved reliability and signal integrity over single-rank modules. Its inclusion of ECC (Error-Correcting Code) enhances the reliability of your server by correcting data errors in real-time, thus maintaining system stability and data integrity. The LENOVO 49Y1440 RDIMM is designed for organizations looking to upgrade or expand their server memory to achieve better performance and efficiency, especially in dense server configurations where cooling and power consumption are critical concerns.
