How to Overclock Note 3 and Make It Fast as a Note 4! [Lean Kernel]

Overclocking has always been one of the biggest reasons to root Android devices including the Note 3.  It can give you full control over the CPU, allowing you to get more juice out of it.  And a lot of people are worried that their CPU will burn up into thin air but on the contrary, mobile CPU processors are different from regular computer processors in that they have been designed to not burn up in case things get hot.

What if I blow up my CPU?

That said, if you are worried about burning out your CPU from too much overclocking, I don’t believe that is physically possible, your CPU will simply shut down or make your phone reboot.  Unlike desktop processors, these mobile processors have been designed so users can abuse the hell out of them.  I’ve overclocked more than 50+ Android devices (and have them run as daily driver) to the maximum for the last 4 years, I have yet to seen a failed CPU from it.

So, do you want to make your Note 3 run fast as a Note 4?  First, the Qualcomm 800 processor on the Note 3 is actually a really good processor for that as it allows stable overclocking to 2.726Ghz, that is actually slightly faster than stock Note 4 frequency of 2.649Ghz.  (On the other hand, Note 4’s Qualcomm 805 processor can overclock to around 2.9Ghz but not beyond that with stability.)
