Product Description
This Samsung M391B5673DZ0-CE7 module is a 2GB DDR3 Unbuffered DIMM (UDIMM), commonly used in desktop computers, consumer laptops, and entry-level workstations. Unlike Registered DIMMs (RDIMMs), UDIMMs do not have registers to buffer command and address signals. This means the memory controller directly interfaces with the memory chips, which typically results in lower latency and cost but limits the maximum memory capacity and stability compared to RDIMMs. The module operates at a speed of DDR3-800MHz, also known as PC3-6400, and features a CAS Latency (CL) of 6. It is configured as 2Rx8, indicating it is dual-ranked with an x8 data width per chip. Dual-rank memory can sometimes offer a performance advantage over single-rank memory by allowing the memory controller to interleave accesses between ranks, potentially improving throughput. The 2Rx8 configuration is a standard for many DDR3 modules. Crucially, this is a non-ECC (Error-Correcting Code) module. Non-ECC memory does not have the built-in error detection and correction capabilities found in ECC memory. While sufficient for most everyday computing tasks, it is generally not recommended for servers or critical workstations where data integrity is paramount. The M391B5673DZ0-CE7 is a standard, cost-effective memory upgrade for compatible desktop systems.
