Description
This Hynix memory module, identified by the part number HYMP512U64AP8-Y4 AB, provides 1GB of DDR2 Random Access Memory. It operates at a clock speed of 667MHz, which was a common performance tier for DDR2 systems. The module is designed as a standard Unbuffered DIMM (UDIMM), meaning it does not have onboard registers and is typically used in desktop computers and some entry-level servers that support this type of memory. The specification 'non-ECC' indicates that the module does not include Error-Correcting Code functionality, making it suitable for general-purpose computing where data integrity is not as critical as in server environments requiring ECC memory. The CAS Latency (CL) of 5 clock cycles is a measure of the delay between the memory controller requesting data and the data becoming available, a typical value for DDR2-667 modules. With a capacity of 1GB, this module is best suited for upgrading older systems or for systems with limited memory requirements. It adheres to the standard DDR2 specifications, including the typical operating voltage of 1.8V. Compatibility should be verified with the specific motherboard or system to ensure it supports DDR2-667MHz UDIMMs.
