A high-strength steel sheet is useful for applications to automobile steel sheets and the like and has excellent deep drawability, a tensile strength of as high as 440 MPa or more, and a high r value, and a process for producing the steel sheet. In one exemplary embodiment, the maximum amount of physical memory that can be used to cache files is reduced prior to performing a dynamic memory removal operation. This measured deviation is then used to adjust the value input to the digital display thereby making the digital display value match the indicated value of the analog speedometer.
