How much Vdroop is too much?
1.45V is dangerously high and I wouldn't recommend pushing that high. Even if you have VDroop going on under heavy load, you're still pumping 1.45V in under lighter load conditions and that can damage the CPU. 1.4V is the absolute maximum Vcore you should be setting and ideally you should be running lower than that.
