Samsung M470T5663EH3-CF 2GB 2RX8 PC2-6400S Laptop RAM

Product Description

The Samsung M470T5663EH3-CF is a 2GB memory module designed specifically for laptop computers that utilize DDR2 SODIMM memory technology. DDR2 (Double Data Rate 2) is an older generation of SDRAM that offers improved performance over its predecessor, DDR, by doubling the data transfer rate through its use of both the rising and falling edges of the clock signal. The SODIMM (Small Outline Dual In-line Memory Module) form factor is standard for laptops and other compact computing devices, differing from the larger DIMMs used in desktop computers. This particular module operates at a speed of PC2-6400, which corresponds to a clock frequency of 800MHz. The '2Rx8' designation indicates its internal configuration: '2R' signifies dual-rank, meaning the memory chip is divided into two independent sets of memory banks, allowing for faster data access. 'x8' refers to the data width of each memory chip, which is 8 bits. This configuration provides a good balance of performance and capacity for systems that support DDR2 memory. With a capacity of 2GB, this Samsung memory module is suitable for upgrading older laptops or replacing existing modules to improve multitasking capabilities and overall system responsiveness. It is important to note that DDR2 memory is not backward or forward compatible with DDR3, DDR4, or newer memory types. Users must ensure their laptop's motherboard specifically supports DDR2 SODIMM modules of this speed and configuration before installation.
