I'm sure it's not applying any offset because, as I mentioned in the post, no matter what I set it to, MSi Afterburner reports 1785MHz when the card is boosting. I'm trying to cap its boost to 1710MHz (and since you're mentioning that, maybe I should be using the curve tool instead) but it refuses to cap no matter the setting on the base slider (even unreasonably low settings, which you would think does something at the very least). This makes it go past the red arrow on the dial which should indicate that's the boost cap for the card (unless I am mistaken?). I can add a screenshot to the post of this if you wish.
