Kingston KST-XW4200-1GB 1GB DDR2-400MHz PC2-3200 Non-ECC Unbuffered CL3 240-Pin DIMM Memory Module

Product Description

The Kingston KST-XW4200-1GB is a 1GB DDR2 Synchronous Dynamic Random-Access Memory (SDRAM) module specifically engineered to boost the performance of desktop computers that utilize DDR2 memory technology. With a clock speed of 400MHz, it corresponds to a PC2-3200 data transfer rate, indicating its capability to move data efficiently within the system. This module is non-ECC (Non-Error-Correcting Code), meaning it does not feature built-in error detection and correction capabilities, which is typical for standard consumer-grade memory modules where performance and cost are prioritized over absolute data integrity for non-critical applications. This memory module is unbuffered, also known as non-registered. Unbuffered memory directly connects to the memory controller, offering lower latency compared to buffered modules. This direct connection can lead to faster response times, which is beneficial for applications sensitive to delay. The 240-pin DIMM (Dual In-line Memory Module) form factor is standard for DDR2 desktop memory, ensuring physical compatibility with motherboards designed for this type of RAM. The CL3 (CAS Latency 3) timing indicates the number of clock cycles the memory takes to respond to a column command, representing a balance between speed and stability for DDR2 technology. As a single-rank module, the KST-XW4200-1GB has memory chips on only one side of the printed circuit board. This configuration is common for lower-density modules and generally does not impact performance significantly in most desktop applications compared to dual-rank modules, especially when installed in single-DIMM configurations. This 1GB module serves as a cost-effective upgrade for systems that may be experiencing performance bottlenecks due to insufficient RAM, allowing for smoother multitasking and improved application loading times on compatible DDR2-based platforms.
