That's correct. I've found the final load voltage with or without droop (by mod or a BIOS setting like the Asus anti-dropp one) is the same for a given oc. In other words, I can set a droop-less idle and load 1.30V or an idle 1.36V/load 1.30V for the same oc. Temps don't really change, idle might be a degree or two higher if that but it's close. If you're running low voltage so the spikes aren't high, above what would be safe, it shouldn't cause any harm to the CPU. Whether it's good for the VRM section even at lower voltage is another issue and beyond me tbh but from what I gather from the older article on techrepository it's probably not good for them either. at higher voltage it very well could cause a problem.
I understand why Asus included this setting from a 'customer demands it' perspective but it seems like most don't understand why it's there. I stopped worrying about droop and just set higher idle voltage.
The only thing a droop fix would change is if 1.5V is the max setting, then you could set it to have a higher load voltage. It wouldn't change temps because you'd just be putting the same or more through the CPU, if your temps are going through the roof at a given voltage they'd do that regardless of droop.
