Hynix HYMP532U64CP6-Y5 AB 256MB (2 x 128MB) DDR2-667MHz non-ECC

Product Description

The Hynix HYMP532U64CP6-Y5 AB is a memory kit comprising two 128MB DDR2 SDRAM modules, providing a total system memory capacity of 256MB. DDR2 technology was a significant advancement over DDR memory, offering higher bandwidth and improved power efficiency. This kit operates at a speed of 667MHz, commonly designated as PC2-5300, which signifies its theoretical peak data transfer rate. The CAS Latency (CL) is set at 5 clock cycles, representing the time delay between the memory controller's command and the availability of data from the memory module. This memory kit is configured as Non-ECC (Non-Error-Correcting Code) and Unbuffered. Non-ECC memory is the standard type used in most consumer-grade personal computers and workstations, where the system's design does not necessitate the overhead of error correction. Unbuffered memory, also referred to as non-registered memory, means that the data signals are passed directly from the memory controller to the memory chips. This architecture is typical for standard desktop and laptop systems, although it may impose limitations on the maximum memory capacity and signal integrity compared to registered memory modules found in servers. With a total capacity of 256MB, this Hynix DDR2 memory kit is intended for older computer systems or specific embedded applications that require DDR2 memory. It is crucial to confirm system compatibility, as DDR2 modules have a different physical keying and pin count than other DDR generations (DDR, DDR3, DDR4), ensuring they can only be installed in compatible motherboard slots. The HYMP532U64CP6-Y5 AB serves as a functional component for maintaining or upgrading systems that rely on this specific type of memory.
