The LENOVO 46W0694 memory module is designed to enhance the performance of servers and workstations that require reliable and efficient memory. With a capacity of 4GB, it provides a substantial upgrade or replacement for systems needing more memory to handle day-to-day operations or more demanding applications. This module uses DDR3 technology, which is known for its balance of performance and power efficiency, operating at 1600MHz (PC3L-12800), ensuring quick data transfer rates for improved system responsiveness. The module's dual-rank (2Rx8) configuration and a low operating voltage of 1.35V make it an energy-efficient option that also supports ECC (Error-Correcting Code), crucial for systems where data integrity is paramount. With a CAS latency of 11 (CL11), it offers a responsive solution for complex computing needs. This ECC DDR3 memory is engineered specifically for compatibility with Lenovo servers, providing a reliable upgrade path with minimal compatibility issues.
