Product Description
The IBM 12R9257 is a 2GB memory module that utilizes DDR (Double Data Rate) technology, operating at a clock speed of 266MHz. This speed corresponds to the PC2100 standard, indicating its data transfer capabilities. The module is specifically designed in a Micro-DIMM form factor, which is significantly smaller than standard DIMMs and SO-DIMMs, making it suitable for ultra-compact laptops, netbooks, or other space-constrained computing devices where larger memory modules cannot be accommodated. This memory module features a 2Rx8 configuration, meaning it is dual-ranked with each rank utilizing x8 (8-bit) memory chips. Dual-rank modules can sometimes offer performance benefits by allowing the memory controller to access different ranks concurrently, potentially improving efficiency. The CAS Latency (CL) is rated at 2.5, which refers to the number of clock cycles it takes for the memory module to respond to a column address command. A CL of 2.5 is typical for DDR266 memory. As an IBM branded part, the 12R9257 is intended to meet the specific memory requirements of certain IBM or Lenovo systems that utilize Micro-DIMM slots. It is crucial to verify system compatibility before purchasing, as Micro-DIMMs are not interchangeable with standard DIMMs or SO-DIMMs. This module provides essential memory capacity to enhance the performance and multitasking capabilities of compatible compact computing devices.
