Abstract: Presence of a module, such as a DIMM, in an information handling system is detected by selectively altering the function of socket pins at opposing ends of the module socket for use in detection of module pins in contact with the socket pins. For example, ground pins at opposing ends of the socket are selectively interfaced with a detection circuit that applies a voltage through a pull up resistor to generate a logic high if the ground pin is not connected to a module ground pin and a logic low if the ground pin is connected to a module ground pin. Presence detection at opposing ends of the module identifies partially inserted modules where one end indicates a ground pin interface while the opposing end does not.
