The LENOVO 46C7418 memory kit consists of two 1GB DDR2 modules, totaling 2GB of memory. It is designed to provide an efficient and reliable upgrade for specific Lenovo servers, with a focus on low power consumption and high reliability. Operating at 667MHz (PC2-5300) with a CAS latency of CL5, this kit offers a balanced approach to speed and latency, optimizing system performance for a range of server applications. The ECC (Error-Correcting Code) feature ensures data integrity, making this kit ideal for servers where data accuracy is paramount. The single rank configuration ensures compatibility and high performance in environments where memory density is not the primary concern. This memory kit's low power design reduces thermal output and energy consumption, contributing to a more sustainable and cost-efficient server operation. It's particularly suited for older systems that require DDR2 technology, providing a cost-effective way to extend their operational lifespan and improve performance.
