Welcome Exory !~ (may not be latest info, new version and all )
once in app can click help box, may be decent guide
geared more for laptops, but much info/comments etc.
I overclock all my old rigs- but now with current setup, i simply max my XMP profile on RAM + setting high performance control panel/power settings in Windows & Nvidia- which places a topmost cores automatically around 5Ghz , and steps the rest. Not a true overclocker config, howev- temps & performance are perfect enough for being a gaming rig =)
