3) You should stop posting guesses.
But for Haswell, SVID works auto,enable or disabled regardless of voltage mode used.
I using adaptive for my Z170 and X99.
Only Z170 on adaptive i cannot disable SVID, even though Asus recommends doing that when OC! lol.
I feel SVID option is a relic of Haswell days. Asus must change description or remove SVID totally for Z170.
In X99, disabling SVID, allows me to tweak the external VRM to CPU if i am not wrong.
Since Z170 is all external VRM, there is no need for this option.
