M391A1K43DB2-CWE Samsung 8GB Single Rank Memory Module

M391A1K43DB2-CWE Overview

The Samsung M391A1K43DB2-CWE is an 8GB DDR4-3200MHz ECC Unbuffered DIMM (UDIMM) designed for entry-level servers and professional workstations that require reliability at a lower memory capacity. With 3200MHz operating speed and 25.6 GB/s bandwidth, it ensures smooth performance for workloads such as basic virtualization, small-scale databases, and business applications.Unlike RDIMMs, this module is unbuffered (UDIMM), meaning it does not use a register between the DRAM and memory controller. This makes it suitable for systems with fewer memory slots where high density isn’t required, but data accuracy and system stability remain critical. The ECC support provides automatic error detection and correction, preventing data corruption and ensuring system reliability.
