Question: what is the difference between desktop ram and laptop ram?
Answer: What differentiates the notebook RAM from desktop RAM is its form factor; that is, its physical size and its pin configuration. A full-size DIMM has 100, 168, 184, or 240 pins and is usually 4.5 to five inches in length. In contrast, a SO DIMM has 72, 100, 144, or 200 pins and is smaller — 2.5 to 3 inches.
