The LENOVO 46C7420 is an 8GB memory kit composed of two 4GB DDR2 modules, engineered to provide an effective and power-efficient upgrade for your server or workstation. This kit operates at a frequency of 667MHz (PC2-5300), which improves system responsiveness and data processing speeds. With a CAS Latency of 5, it balances speed and latency to deliver consistent performance. These modules are ECC (Error-Correcting Code) enabled, which means they can detect and correct internal data corruption, offering a critical layer of data integrity and system stability. This feature is particularly important in servers and workstations that handle vital data. The 'Low Power' specification ensures that these modules operate with reduced energy consumption, contributing to lower operating costs and a reduced environmental impact. Designed for systems requiring reliable and efficient memory, the LENOVO 46C7420 kit is an ideal choice for upgrading critical infrastructure.
