Archer C60 V2 overclock, how to?

I want to understand if i can overclock my device modding the uboot.
There is a "human readable" way on how to edit/reflash binaries somewhere?
I've downloaded sources too from tplink, but i have no idea on how to compile them correctly.
Seems that out there there are no (clear) specific infos on how to do it on my device...
Someone that point me in the right direction?
Thanks =)
