Product Description
This Hynix memory module, part number HYMP564U64AP8-Y4 AA, offers 512 megabytes of DDR2 memory. It is designed to operate at a frequency of 667MHz, a common speed for DDR2 modules used in systems from the mid-2000s. As an Unbuffered DIMM (UDIMM), it is intended for standard desktop computers and workstations that do not require the buffering capabilities of registered DIMMs (RDIMMs). The module is specified as non-ECC, meaning it lacks error detection and correction capabilities. This is typical for consumer-grade memory modules and is suitable for general computing tasks. While the CAS Latency (CL) is not explicitly stated in the provided title, DDR2-667 modules commonly feature a CL5 timing, which represents the number of clock cycles required to access data. With a capacity of 512MB, this module is suitable for upgrading very old systems or for systems with minimal memory demands. It operates at the standard DDR2 voltage of 1.8V. Users should confirm motherboard compatibility for DDR2 memory, specifically the 667MHz speed and UDIMM form factor, before installation.
