IBM 64Y6649 2GB DDR3-1333MHz UDIMM 2Rx8 CL9 Memory

Product Description

The IBM 64Y6649 is a 2GB DDR3 Synchronous Dynamic Random-Access Memory (SDRAM) module. This Unbuffered DIMM (UDIMM) is designed for use in compatible IBM computer systems, serving as either a direct replacement for a faulty module or an upgrade to enhance system responsiveness. Operating at a frequency of 1333MHz, it provides a solid foundation for everyday computing tasks, including web browsing, document creation, and light multimedia consumption. The module features a CAS Latency (CL) of 9, which refers to the number of clock cycles required for the memory to access a specific column address. A CL9 rating at 1333MHz is standard for DDR3 memory of this generation, offering a balance between speed and efficiency. The 2Rx8 designation indicates that the module is dual-ranked, meaning it has two independent sets of memory chips (ranks), and each rank is organized with 8-bit wide data paths. This configuration can potentially improve performance by allowing the memory controller to switch between ranks, reducing wait times. As a non-ECC (Error-Correcting Code) module, the 64Y6649 is intended for standard desktop or workstation environments where the highest levels of data integrity are not paramount. It utilizes a 240-pin interface, which is standard for DDR3 UDIMMs. This memory module is a reliable component for maintaining or improving the operational performance of compatible IBM hardware, ensuring smooth execution of common software applications.
