The LENOVO 49Y1435 memory module offers a quick and efficient way to increase system performance in Lenovo servers and workstations. With a capacity of 4GB, this module allows users to run more applications simultaneously or work with large data sets without experiencing slowdowns. It utilizes ECC (Error Correcting Code) to automatically detect and correct memory errors, thereby enhancing system reliability. The module operates at a speed of 1333MHz, providing quick access to data and improving overall system responsiveness. A voltage of 1.5V ensures compatibility with a wide range of systems without significantly increasing power consumption. Furthermore, its 2Rx4 configuration indicates a dual rank, offering better signal integrity and potentially improving memory bandwidth compared to single-rank modules. Being a Registered DIMM (RDIMM), it stabilizes the data signal by registering the signal to a specific register within the module, allowing for greater system stability and increasing memory capacity. The Low Profile (LP) design of this RDIMM makes it suitable for servers and workstations where space is at a premium, without sacrificing performance. This memory module is specifically engineered for compatibility with Lenovo systems, ensuring a reliable and seamless upgrade experience.
