You're talking the auto-OC functionality?
Same as it's ever been... at least for the last few gens.
It's essentially just a lookup table: If you have X CPU, then Y is commonly available, test, rinse & repeat.
A decent starting point, but will generally always over-volt for a given clock speed.
Worth checking out what the "auto" aspect thinks the chip is capable of, just to get an idea, then work from there manually.
