So what you're saying is that if I find a good enough cooling solution, I can push 10V through my chip and set a world record at 15GHz without any damage?!?!
Sweet, I'm off to find liquid nitrogen. /sarcasm
No but seriously, voltage can damage a chip, it's not all due to heat. I'm pretty sure if you had a chip running at stock settings, and suddenly the voltage on it spiked to 10V for even one cycle, that chip would be flat out fried regardless of the cooling solution.
Also I have first-hand experience in the matter. My chip used to run at 4.8GHz @ 1.35V. However I was using a very old (over 6 years) 1000W PSU. The PSU started getting iffy and was throwing out voltage fluctuations. Eventually it degraded my CPU to the point that it started getting unstable. By the time I had tracked down the problem, it was too late, the damage was done. I ordered a new PSU, but now I have to push 1.381V to be stable. Odds are, that constant voltage spikes are the cause. They weren't sky high like the OP's 1.9, usually fluctuating within .3V that CPUZ could catch, but I don't doubt there were possibly worse, larger spikes that really helped it along.
Based on this, yes the OP's CPU may have been damaged a bit by excessive voltage, and like my chip is more power hungry as a result.
