The Lenovo 00D5020 memory module boosts the performance and reliability of Lenovo servers and workstations that need high-speed memory. This 4GB DDR3 ECC RDIMM module operates at a standard voltage of 1.5V, designed for systems that can take advantage of higher-speed memory running at 1866MHz (PC3-14900). It features a 1Rx4 configuration, meaning it has a single rank populated with four memory banks. Such a setup enhances compatibility and stability in multi-module configurations. With ECC (Error-Correcting Code) technology, it corrects data corruption on-the-fly, ensuring high reliability and system uptime. The module's CL13 CAS latency is finely tuned for timely data access and processing, optimizing the performance of memory-intensive applications and workloads in a low profile (LP) form factor that ensures compatibility with a variety of system cases and configurations.
