Increasing processor Ghz

[Girindra Arya Satya]

So first all... i got an Asus laptop. The model is...
ASUS A455L , i5-420U. Ram 4GB, Nvidia 820m,

what i wanna ask is... how to increase my Ghz speed?
my current ghz speed is 2.40Ghz...and then i saw some sticker about spec. and it said that my ghz speed is up to 2.7 Ghz. that means....there's a possibility that i can increase my processor speed right?

If i can? how can i do it?
(sorry for bad english)

The CPU overclocks itself based on the number of cores being used and how hot the CPU is. The i5-4210u will only hit 2.7GHz when just one core is used and it is not too hot. When both cores are used, the max is probably 2.4GHz. There is nothing you can do.
