Product Description
The Samsung M391B5673EH1-CF7 is a 2GB DDR3 Unbuffered DIMM (UDIMM) memory module. Unbuffered DIMMs are typically used in desktop computers, workstations, and some entry-level servers where the memory controller can directly drive the memory modules without the need for an intermediate register. This makes UDIMMs generally less expensive and sometimes faster in lower-density configurations compared to Registered DIMMs (RDIMMs), but they are limited in the total amount of memory a system can support due to the increased electrical load on the memory controller. This module operates at a frequency of 800MHz, which corresponds to PC3-6400 data transfer rates. It features a CAS Latency (CL) of 6, indicating the number of clock cycles required to access data after a command is issued. The configuration is 2Rx8, meaning it is a dual-rank module with an x8 data width per rank. Dual-rank modules can offer performance benefits by allowing the memory controller to access different ranks, potentially improving throughput. As a DDR3 module, it is compatible with motherboards and systems that specifically support the DDR3 standard. The 2GB capacity and UDIMM form factor make it suitable for upgrading or populating memory in systems that do not require the advanced features or higher densities offered by RDIMMs. It's crucial to verify system compatibility with DDR3 UDIMMs of this speed and rank configuration.
