Product Description
This 8GB DDR4 Unbuffered DIMM (UDIMM) from Samsung, identified by SKU M391A1G43EB1-CPB, offers a balance of capacity and speed suitable for a wide array of computing needs. Operating at 2133MHz, it provides a noticeable performance uplift over older DDR3 modules, making it a solid choice for general-purpose computing, office productivity, and light server tasks. The 2Rx8 configuration indicates a dual-rank design, which can offer improved performance in certain scenarios by allowing the memory controller to access different ranks of memory simultaneously. The CAS Latency of CL15 signifies the number of clock cycles required to access a particular column in a row, contributing to the module's overall responsiveness. Designed to meet standard JEDEC specifications, this memory module is generally compatible with most consumer-grade motherboards and entry-level servers that support DDR4 UDIMMs. Its 1.2V operating voltage ensures power efficiency, aligning with modern computing standards.
