fixed

this is why we use dice and ln2 to achive higher overclocks, you try to run 1.7v through a chip on air cooling it will kill it within hours, same 1.7V with dice or ln2 cooling will be just fine after 8+hours under the cold.

Voltage kills much faster than heat. CPUs typically throttle if they get too hot. And if it gets past a certain temperature, they actually shut down to prevent damage.

On the other hand, if you're running on LN2 and pump 2v into a 2600k, well I think you would have a dead chip very very fast.

For 24/7 usage both heat and voltage can degrade/kill the chip eventually. If you are doing bench tests you can use higher voltages for a few hours, but not too often or it most likely will degrade the chip. The point is low vcore and temps for 24/7 and push as much as you can for benches.

No... Or you dind´t explain yourself well enough.
Actually the right answer, is that it isnt no right answer.

1st-How high you can go depends on making Processe 65nm,45nm or 32nm(susciptable to less voltage)
2nd-Time you Pretend to keep it up.
3rd-Overclocking ins't a exact Science. it dependes in a lot of variables.

Judging from first impression is that you have no problem keeping a 45nm Proc with 1,7v with Load Temps ~65C.Or 1,9v with Nitrogen(cold), has you said that will make it degradate ,loosing OC capabilities.

We, use it because we can't get system stable at those kind of voltages with any AirCooler or Wc in the market. It just gets too damn hot, too fast!

Anyway keep withing "safe" range for Voltages and Temps AMD or Intel indicated max , and you should be fine , has long has your temps don´t go too high (80's).
