Samsung M391A2K43BB1-CRC 16GB DDR4-2400MHz ECC DIMM Dual Rank Memory

Product Description

The Samsung M391A2K43BB1-CRC is a 16GB DDR4 Synchronous Dynamic Random-Access Memory (SDRAM) module designed for server and workstation applications. This module features Error-Correcting Code (ECC) functionality, which is critical for maintaining data integrity in systems where reliability is paramount. ECC memory can detect and correct common types of internal data corruption, preventing system crashes and data loss that might occur with non-ECC memory. Operating at a frequency of 2400MHz (PC4-19200), this DIMM offers a good balance of performance and capacity for a wide range of computing tasks. The 'Dual Rank' designation indicates that the memory module has two independent sets of memory chips, allowing the memory controller to access data from either rank, which can improve performance through rank interleaving. The specific configuration of the DRAM chips (e.g., x4 or x8) will determine the exact rank structure, but dual rank generally provides better bandwidth utilization than single rank. This memory module is suitable for deployment in servers, high-end desktops, and workstations that require stable and error-free operation. Its standard DIMM form factor ensures compatibility with a vast array of motherboards that support DDR4 ECC memory. When selecting memory, it is always recommended to consult the system's documentation or Qualified Vendor List (QVL) to ensure compatibility and optimal performance.
