Yeah it's clear that my chip is struggling if it needs to spike with the vdroop at 1.36 to be stable. So now that I did everything possible, maybe is healthier to downclock him maybe at 4.9 and trying to keep the vcore lower.for 5.0-5.1 clocks i would not change your board. voltage baseline for a good chip is 1.0-1.1v @ 5.0, you might just have a lower bin, don't sweat it.
