Product Description
This Qimonda memory module, identified by SKU HYS64T128021EDL-25B2 and title 'Qimonda HYS64T128021EDL-25B2 1GB DDR2-800MHz SODIMM 2Rx8 CL6 Memory', is a 1GB stick of DDR2 Synchronous Dynamic Random-Access Memory. It is engineered for compatibility with laptops and other compact computing devices that employ the SODIMM form factor and support DDR2 memory technology. Running at a frequency of 800MHz, it corresponds to the PC2-6400 standard, offering a good performance level for systems of its generation. The module features a 2Rx8 organization, signifying that it is dual-ranked with an eight-bit data width per rank. This configuration can sometimes provide performance benefits depending on the system's memory controller. The CAS Latency (CL) is specified as 6, meaning it takes 6 clock cycles for the memory to respond to a column address command. This CL6 timing at 800MHz is a common and reliable specification for DDR2 memory modules. As a Non-ECC (Non-Error-Correcting Code) module, this memory is intended for standard consumer and business laptops where error correction is not a critical requirement. The SODIMM form factor is crucial for its integration into the tight spaces within portable computers. This 1GB DDR2 module is a suitable choice for upgrading the memory capacity of compatible laptops or replacing a faulty memory module, thereby improving system responsiveness and multitasking capabilities.
