The LENOVO 46W0779 is a high-capacity 16GB ECC DDR3 memory module, ideal for use in enterprise-grade servers and workstations that demand high levels of reliability and performance. Operating at a frequency of 1866MHz (PC3-14900) and a CAS latency of 13 (CL13), it ensures prompt data processing and system responsiveness. The module's standard operating voltage of 1.5V ensures compatibility with a wide array of DDR3-based systems. It employs ECC (Error Correcting Code) technology to detect and correct data errors in real-time, enhancing system stability and reducing the risk of data corruption. The 2Rx4 configuration signifies a dual-rank module that improves signal integrity and reliability over single-rank modules. This memory is ideal for organizations looking to expand their system's memory capacity, ensuring smooth operation and efficient handling of memory-intensive applications.
