Product Description
The Qimonda HYS64T128020EU-25F-B2 is a 1GB DDR2 Unbuffered DIMM (UDIMM) memory module. UDIMMs are the standard type of RAM used in most desktop computers and are not registered, meaning they send commands and addresses directly to the memory chips. This module operates at a speed of 800MHz, commonly referred to as PC2-6400, which was a high-performance speed for DDR2 memory. This specific module is configured as 2Rx8, indicating it is dual-ranked with eight memory chips per rank. Dual-rank modules can sometimes offer improved performance by allowing the memory controller to access different ranks of memory chips more efficiently. It features a CAS Latency (CL) of 6, which represents the number of clock cycles required for the memory to respond to a column access command. This is a relatively low latency for DDR2 memory, contributing to its responsiveness. This Qimonda memory module is non-ECC, meaning it does not have error-correction capabilities, which is typical for consumer-grade desktop memory. With its 240-pin connector, it is designed for motherboards that specifically support DDR2 memory. It serves as a viable option for upgrading older systems or replacing faulty memory modules in compatible hardware.
