M391A5143EB1-CPB00 - Samsung 4GB DDR4-2133MHz PC4-17000 ECC Unbuffered CL15 288-Pin DIMM 1.2V Single Rank Memory Module

Description

The Samsung M391A5143EB1-CPB00 is a 4GB DDR4 Unbuffered DIMM (UDIMM) memory module, designed for standard desktop computers and workstations. Operating at a frequency of 2133MHz, which corresponds to the PC4-17000U standard, this module offers a good balance of performance and power efficiency for everyday computing tasks. The CAS Latency (CL) of 15 indicates the number of clock cycles required to access a particular column in memory, contributing to the module's overall responsiveness. This UDIMM features a 1Rx8 organization, signifying a single rank with an x8 data width per DRAM chip, a common configuration for consumer-grade memory. As an Unbuffered DIMM (UDIMM), this memory module does not have onboard registers. Instead, the memory controller directly communicates with the DRAM chips. This design is simpler and generally less expensive than registered memory, making it ideal for mainstream consumer systems where extreme memory capacities or densities are not typically required. While it lacks ECC (Error-Correcting Code) functionality, which is standard for server-grade memory, it is perfectly suited for typical desktop usage where the risk of critical data corruption from single-bit errors is lower. This 4GB DDR4 module is a reliable choice for upgrading the memory in compatible systems or for building new PCs. It provides sufficient capacity for multitasking, running common applications, and general web browsing. Users should verify their motherboard's specifications to ensure compatibility with DDR4 2133MHz UDIMMs before installation.
