MCCPU boosts up very aggressively by 800% and boosts down very mildly by 10%. This doesn't work well when system is idling because the very slow de-boosting results in lots of consecutive-down interrupts, in result memory stays clocked high and CPU doesn't enter deepest idling state instead of keeping memory at lowest freq and having CPU cluster turned off. A more faster de-boosting fixes the case of idling system and doesn't affect the case of an active system.
