Easy Tuner Gigabyte

Hi there!
I am about to OC my i7 6700k and this is my first time stepping into OC.
Now I know the standard and recommended procedure would be to go into the BIOS to do so, but I wanted to have a look at Gigabyte's EasyTune software first, mainly to see if I can change the multiplier and voltage from there, which seems to be possible in the Advanced CPU OC panel. I wasn't planning on using AutoTuning or any default 'profile' whatsoever.
Now what I want to know is if it is reliable? Do the changes I make there reflect on the BIOS, or is it something that will be reapplied at every restart? Not that it's a problem, I can simply use it to test the system and then go the BIOS to apply the changes (and probably Adaptive voltage, as this option seems to be missing from EasyTune) ; or is it too much trouble?
Thanks for reading and answering!
