The invention provides an out-of-band reading detection method and an out-of-band reading detection device for a cache consistency chip address. The method comprises the following steps: sending configuration information to a logic detection storage module by a configuration reading module; recording message information by the logic detection storage module according to the configuration information; when the consistency problem occurs, reading the message information from the logic detection storage module by the configuration reading module. The out-of-band reading detection method and an out-of-band reading detection device for the cache consistency chip address, provided by the invention, have the characteristics that configuration is flexible, the storage resource consumption is low, the readability is strong, and the operation is convenient.
