Product Description
This Samsung M391B5273BH1-CH9 module is a 4GB DDR3 memory stick designed for compatibility with a wide range of motherboards and systems that support unbuffered DIMMs. It is a standard component for upgrading or populating memory in desktop computers, workstations, and some entry-level servers. The DDR3 technology offers a good balance of performance and power consumption for its generation. The Unbuffered DIMM (UDIMM) design means that the memory chips are directly connected to the memory controller without an intermediate register. This configuration is common in consumer-grade systems and some servers, offering a simpler architecture. However, it places a higher electrical load on the memory controller, which can limit the maximum number of modules that can be installed in a system compared to RDIMMs. With a speed of 1333MHz (PC3-10600) and a CAS Latency of CL9, this module provides adequate performance for everyday computing tasks, office applications, and moderate multitasking. The 2Rx8 configuration indicates it is dual-rank, which can offer performance benefits by allowing the memory controller to access different ranks of memory simultaneously. This module is typically Non-ECC, meaning it does not have error-correcting capabilities, which is standard for most desktop systems.
