Besides some early 32nm's/gulftowns that died at 1.5+V, the only chips that ever died from being moderately overvolted were those pentium 4 northwoods; some degraded severely, some died. (I had one that used to do 3.9 ghz at 1.7v, degraded badly to the point where it only did 3.4 ghz at stock, and would freeze in POST at 3.6 ghz).
As far as newer chips, it's hard to say.
Some chips degrade slightly (0.025-0.05v) then work continuously from there. It seems that low vid, high leakage chips (higher heat?) respond more favorably to vcore than cool, high vid chips. I don't think anyone has tested it yet, but I wonder if cool high vid chips degrade more than hot, low vid "leaky" chips, since the cool high vid chips don't respond as well to voltage? No idea about cool low vid chips...
