Product Description
The IBM 12R9264 is a 4GB memory module specifically designed for systems that require the Micro-DIMM form factor. Micro-DIMMs are significantly smaller than standard DIMMs and SODIMMs, making them suitable for highly compact computing devices such as certain laptops, small form factor PCs, or specialized embedded systems where space is at a premium. This module utilizes DDR (Double Data Rate) SDRAM technology. Operating at a clock speed of 266MHz, this module corresponds to the PC2100 standard, indicating a theoretical bandwidth of 2100MB/s. The CAS Latency (CL) is rated at 2.5, which refers to the number of clock cycles it takes for the memory controller to access a specific column in a row of memory. The 4Rx8 configuration signifies that the module has four independent memory banks (ranks), each organized as 8 bits wide, which can affect performance and compatibility in certain multi-channel memory configurations. This specific IBM part number ensures compatibility with IBM systems that have been designed to accept this type of memory. Upgrading or replacing memory with the correct specifications is crucial for maintaining system stability and performance. The 4GB capacity provides a substantial boost for systems that may have come with lower amounts of RAM, improving multitasking capabilities and overall system responsiveness.
