Product Description
The IBM 12R6971 is a 2GB memory kit comprised of four 512MB DDR SDRAM modules. These modules utilize the Micro-DIMM form factor, which is significantly smaller than standard DIMMs, making them suitable for highly compact computing devices such as ultra-portable laptops, embedded systems, or specialized industrial equipment where space is at a premium. The DDR-266MHz speed offers a foundational level of performance for systems of its era. Each 512MB module is configured as 1Rx8, indicating a single rank with an x8 data width. This configuration is typical for lower-density memory modules and is optimized for compatibility with a wide range of system architectures. The CAS Latency (CL) of 2.5 is a measure of the delay between the memory controller issuing a read command and the data becoming available from the memory module. A CL of 2.5 at 266MHz represents a standard performance characteristic for DDR memory of this generation. This memory kit is designed to meet the specific memory upgrade or replacement needs of systems that are equipped with Micro-DIMM slots. Its compatibility is tied to the system's chipset and BIOS support for DDR memory at 266MHz and the Micro-DIMM form factor. Users should verify system specifications before purchasing to ensure proper fit and functionality.
