Product Description
The IBM 52P8679 is a memory kit providing 512MB of DDR memory in a Micro-DIMM form factor. Micro-DIMMs are significantly smaller than standard DIMMs or SODIMMs, making them suitable for highly compact devices such as ultra-portable laptops, certain mobile phones, or specialized embedded systems where space is extremely limited. This particular module operates at a clock speed of 266MHz, which is characteristic of early DDR memory standards. The 2Rx8 configuration indicates a dual-rank module, where each rank comprises eight memory chips. This setup can offer improved performance by allowing the memory controller to access data from different ranks in an interleaved fashion. The CAS Latency (CL) of 2.5 is relatively low, contributing to faster data access times for the given clock speed. This memory kit is designed for systems that specifically support DDR Micro-DIMMs and operate at 266MHz. Given its age and form factor, it is likely intended for older IBM ThinkPad models or other niche devices. Compatibility must be strictly verified with the target system's specifications, as Micro-DIMMs are not interchangeable with other memory types.
