Woah, settle down Francis.WOAH.
I never said anything about failure. I am talking about drift and degradation.
If the motherboard displays 1.45 volts and delivers 1.45 volts in 2014.
BUT in 2017 it displays 1.45 volts but actually only outputs 1.43v.
Would you trust a 3 year old never calibrated motherboard and it's related voltage measuring systems, no, you would want it verified with another measurement device.
That's all I'm saying.
