@hansglans Technically, it's not necessary, but if you want your computer to function properly it is. I ran into significant instability when not using it. I have a theory that it trying to boost and throttle as it normally would while trying to use my manually set voltage, which would crash at the lighter threaded turbo speeds.
When using the patch, my settings would work fine. Unfortunately, that patch isn't persistent between boots.
I'm not sure about the transferrability of OC profiles, I wasn't able to save the profiles from my non-modded Dark bios anyways.
