Product Description
The Qimonda HYS64T128020HU-25-B is a 1 Gigabyte (GB) DDR2 Unbuffered DIMM (UDIMM) memory module. It operates at a speed of 800MHz, corresponding to the PC2-6400 standard, and features a CAS Latency (CL) of 6. This module is designed for desktop computers and workstations that utilize the DDR2 memory interface, which was prevalent in systems manufactured roughly between 2003 and 2008. This memory module is non-ECC, meaning it does not include error-checking and correction capabilities, making it suitable for standard consumer-grade systems rather than servers or workstations where data integrity is critical. As an unbuffered module, it directly interfaces with the memory controller, offering potentially lower latency compared to buffered modules but with limitations on the total memory capacity per channel. The module uses a 240-pin connector and operates at a voltage of 1.8V, which is standard for DDR2 memory. It is an ideal component for users looking to upgrade the RAM in older computers to improve performance for multitasking, running more demanding applications, or extending the useful life of their existing hardware. Compatibility with the specific motherboard chipset and CPU is essential for proper function.
