Product Description
This Hynix memory module, part number HYMP564U64AP6-Y5 AA, provides 512MB of DDR2 memory. It is designed to run at a speed of 667MHz, a common specification for DDR2 modules used in systems from the mid-2000s. The module is an Unbuffered DIMM (UDIMM), which is standard for most desktop computers and workstations that do not require registered memory. The module is non-ECC, meaning it does not feature error-correcting code functionality, making it suitable for general computing purposes. While the CAS Latency (CL) is not explicitly stated in the title, DDR2-667 modules typically operate with a CL5 timing. This timing indicates the number of clock cycles it takes for the memory to respond to a request for data. With a capacity of 512MB, this module is intended for older systems or those with very basic memory needs. It operates at the standard DDR2 voltage of 1.8V. Compatibility with the motherboard's DDR2 memory controller, speed, and form factor should be confirmed prior to installation.
