Problem for voltage settings in clock configurations

I've noticed that, in our SDK, like the SDK for LPC546xx, if we want to change the clock frequency, we need to call the function:

POWER_SetVoltageForFreq( freq )

But if I remove this function, the MCU can also runs. What has this function done? Why do we need to call it?
