Product Description
The Samsung M391A1G43EB1-CRC is a standard 8GB DDR4 memory module designed for contemporary computing systems. As a DDR4 UDIMM, it offers significant improvements in speed, power efficiency, and density compared to previous DDR generations. This module operates at a frequency of 2400MHz (PC4-19200), providing ample bandwidth for demanding applications, multitasking, and gaming on compatible desktop computers and workstations. The 2Rx8 configuration indicates that the module is dual-ranked, with each rank comprising eight data bits per DRAM chip. This organization can enhance performance by allowing the memory controller to interleave access between ranks, reducing latency and improving throughput. The CAS Latency (CL) of 17 signifies the number of clock cycles required for the memory module to respond to a column address command. This timing, along with the 2400MHz speed, defines the module's performance characteristics for everyday computing tasks. Operating at a lower voltage of 1.2V compared to DDR3, this module contributes to reduced power consumption and heat generation, making it an energy-efficient choice. It is important to note that this specific model is a non-ECC UDIMM, which is standard for most consumer-grade motherboards and typical desktop applications. For systems requiring error correction, a Registered ECC (RDIMM) or Unbuffered ECC (ECC UDIMM) module would be necessary. Samsung's rigorous quality control ensures reliability and compatibility with a wide array of DDR4-enabled systems.
