That means if OS is going down with speed step by step it will take a while until you reach 2.4 GHz.

No idea whether it helps, but I would give it a try. Maybe you find some specs on the Intel site what speed steps should be supported and how many power/temperature gain you can get. 2.4 GHz doesn't sound like you save a lot of energy... Thomas
