Is your llc on extreme? Please answer my questions when I ask them. You seem to be mixing up llc, every compnay uses a different terminology, asus on extreme is the same as asrock level 1 (reducing vdroop), msi disabled can be the same as asus enabled so it's important to know your mobo. At 4.5ghz there's really no reason to go past medium so you can keep the vcore lower.
Vdroop is a good thing until it makes your OC unstable as you want the lowest vcore you can get til it's unstable. I'm sure what you are seeing is just the voltage being regulated to meet your load. But I've never seen the voltage going higher in a game than prime. What other settings have you changed?
Try changing the vrm to auto. Everything else is what I usually see. It's weird that your vcore is going that low. My offset is -.05 and never goes below .9 at idle, 1.3v at load and hardly fluctuates.
