Nanya NT512D64S8HAAG 512MB DDR-266MHz PC2100 Non-ECC Unbuffered CL2.5 184-Pin DIMM Memory Module

Product Description

The Nanya NT512D64S8HAAG is a 512MB memory module belonging to the DDR SDRAM generation, specifically designed for systems that require PC2100 speed. Operating at a clock speed of 266MHz, this module provides a data transfer rate suitable for older desktop computers and servers. It is an unbuffered module, meaning it does not have a register to buffer command and address signals, which is typical for mainstream consumer and entry-level server applications of its era. The Non-ECC (Error-Correcting Code) designation indicates that it does not have built-in error detection and correction capabilities, making it best suited for environments where data integrity is less critical or handled by the motherboard. This DIMM features a standard 184-pin connector, which is characteristic of DDR memory modules, distinguishing it from earlier SDRAM (168-pin) and later DDR2 (240-pin) modules. The CAS Latency (CL) of 2.5 indicates the number of clock cycles required for the memory to respond to a column access command. While CL2.5 is a common timing for DDR266 memory, it represents a specific performance characteristic that users should consider when matching it with existing system memory or evaluating compatibility. This 512MB module is a component for systems that have reached their end-of-life or are maintained for specific legacy purposes. It is crucial to ensure compatibility with the motherboard's chipset and existing memory configuration before installation, as DDR memory is not backward or forward compatible with other DDR generations. The Nanya NT512D64S8HAAG serves as a replacement or upgrade part for systems that originally used this type of memory.
