RivaTuner's task scheduler module was designed special for such tasks. Go to <Scheduler> tab, click <Add new task> button and type in task name, e.g. "Voltage mod", select <Launch application on specified schedule> task type in %RT% macro as path (RivaTuner will expand it into fully qualified path to itself when executing) and desired I2C writec commands in the command line field then selct desired schedule type, e.g. <Run task at RivaTuner startup>.
