Product Description
The Samsung M391B5673DZ0-CF7 is a 2GB DDR3 Unbuffered DIMM (UDIMM) memory module designed for standard computing platforms. It operates at a frequency of 800MHz, corresponding to a PC3-6400 data rate, and has a CAS Latency (CL) of 6. The 2Rx8 configuration indicates that the module consists of two ranks, with each rank using eight memory chips. This configuration is common for UDIMMs and provides a balance of capacity and performance for general-purpose computing. As an Unbuffered DIMM (UDIMM), this memory module does not include the registers found on RDIMMs. Instead, the memory controller directly communicates with the DRAM chips. This design makes UDIMMs generally less expensive and suitable for systems where the number of memory modules is limited, such as most desktop computers and some entry-level servers. The direct signaling path can offer slightly lower latency in some scenarios compared to RDIMMs. This module also supports ECC (Error-Correcting Code) functionality, which is a valuable feature even in unbuffered memory. ECC helps to detect and correct single-bit errors in memory, enhancing system stability and data integrity. While UDIMMs are typically used in less memory-intensive environments than RDIMMs, the inclusion of ECC provides an added layer of reliability for critical data processing tasks.
