Lenovo 4GB DDR4 2133MHz ECC Registered

A powerful and reliable DDR4 server memory module for high-end systems, servers, and multiprocessor PCs. This module is primarily designed for Lenovo high-performance workstations, such as ThinkStation P500, P700, or P900. The module was rigorously tested to ensure its reliability under heavy workload, making it ideal for important applications.
ECC technology performs real-time integrity checks of the data stored in memory. This allows it to find and fix single-bit errors and detect errors of two bits per 64-bit word. Some memory controllers can also repair larger errors in conjunction with ECC memory. Most server motherboards require memory with ECC support.
