Load line calibration can cause major spikes, so it's worth being mindful of that. Numbers above that are just speculation. Numbers below that are just preference.
That was for the AM2 Phenom II 940.

I mean, yes that's true but chew has already seen degradation of Thuban around 1.52v.

That's partially why I've changed the chart so all non-Thuban CPU's are 1.55v for 24/7.
