Product Description
This Nanya memory module, identified by SKU NT256D64S88AAG, is a 256 Megabyte Synchronous Dynamic Random-Access Memory (SDRAM) module built on the DDR (Double Data Rate) technology. It operates at a clock speed of 266MHz, which translates to a bandwidth of 2100 Megabytes per second (MB/s), hence its PC2100 rating. This module is designed for standard desktop and server applications that require reliable memory performance without the need for error correction. The module utilizes an unbuffered architecture, meaning data signals are not stored or processed by an on-module buffer chip, leading to lower latency and direct access for the memory controller. The CAS Latency (CL) of 2.5 indicates the number of clock cycles it takes for the memory module to respond to a column address strobe command. Its 184-pin DIMM form factor is standard for DDR memory, ensuring compatibility with a wide range of motherboards and systems that support this memory generation. Ideal for system upgrades or replacements, the NT256D64S88AAG provides a significant boost in memory capacity for systems that may be limited by older or smaller RAM modules. Its Non-ECC nature makes it suitable for general-purpose computing, gaming, and multimedia tasks where the overhead of ECC is not required. The module adheres to industry standards for DDR-266MHz memory, ensuring interoperability and stable operation within compatible systems.
