Any ideas how what vcore for i7 980X would cause it to degrade - when applied in couple hours benching sessions (mostly Futuremarks)?

Example:
Vcore: 1.56v (as reported in CPU-Z under load, done through offset so dropping to ~1.27 under light load)
QPI: 1.35
DRAM: 1.64(or 1.66)
PLL: 1.90

With LLC on at 1000mv, on water temps well under the safe margin.

Any thoughts? I realise that every cpu is different etc. but I reckon who else can have some first hand experience
I know I and others who have had 45nm i7s like the 920s who ran them on phase or cascade at 5ghz high voltages through futuremark benches for over a year all the time. Sometimes after a while the chip will wear down and you'll have to lower the clocks a little bit(maybe 50-100mhz) with the same voltages to get stable again. I don't think its bad though.
If you beat it hard it for 5 years though it would probably degrade a lot. But considering, most people upgrade before then and that will not be there top end benching system anymore.
