3800x is is already at it's maximum, there's no point in overclocking it. Without subzero cooling you'd never get all cores even to 4.5GHz let alone over. Best way to get maximum performance is to have good cooling, enable boost and PBO and make sure that MB is good for 4000MHz RAM as fast memory helps CPU performance.
You could set a manual frequency to 4.5 but that's highly unlikely and with anything bellow that you would loose on single core/thread performance while gaining little in multicore.
