I believe, A DIMM (Dual In-Line Memory Module) typically has 288 pins. This is the standard configuration for DDR4 and DDR5 DIMMs, which are commonly used in modern desktop and server computers. However, it's important to note that the number of pins can vary depending on the specific type of DIMM and the generation of DDR (e.g., DDR3, DDR2, etc.) being used. Each generation of DDR memory module may have a different pin configuration.
