Actually Theo Said:

"Yes, you’ve read it correctly – from -200 to +100, you can be certain that your Phenom will not fail. On-die sensors are tweaked up and they will not lock the part at -100 or -20C, and you can use dry ice or LN2 to crank it up to the max."

Not sure why you decided to leave out that part of the quote, but that would implie (at least to me) that it was a tweak made to the core. Not diasabled sensors...
