Are you saying that 1.38 is the absolut max vcore where the chip won't see any degradation?

From what I understand degradation even happens at stock voltages but they happen so slow that either the platform is totally obsolete or other parts just die out first ( multiple times ).

1.380v is some sort of an acceptable voltage that should keep your processor running w/o much of a trouble maybe for 5yrs or so?

I had my Q6600 at 1.475 24/7 for 3yrs and 3 months and never had any degradation but all chips are different.

I guess if you plan to upgrade every 3yrs or so 1.380~1.460 should be your max limit, if you plan to upgrade every generation. 1.500v all day long!

If your processor degrades with in 3yrs or less Intel should be able to replace it but thats like scamming intel for the misuse of your processor.

65nm chip vs 32nm chip.

Big difference.

You may have missed the last part, take it has a whole and not just a select line.

I did read the whole post.

The way it reads implies that the voltages that can be used on a 65 nm chip should be extended to a 32 nm chip. Just because you can pump 1.47 volts into a 65 nm quad without issues for years doesn't mean you can pump 1.46 into a 32 nm quad and expect it to hold up the same, lol.

Irrelevent 1..475v is still above intels max recommended limit for 65nm

People are still pumping more vcore than intel's max on 65nm with no problems.

As people are doing on 32nm, and will again on 22nm. Given the max voltage gets lower each time the manufacturing process gets lower people still cross the safe limits everytime regardless of manufacturing process

Meh. I'll fold on my chip till it dies. Then I'll get another one and see if it'll clock any higher

I cant see how this is missed.

Pretty much means 65 and 32 are different.

The fact is nobody knows the vcore when the chips starts to get degraded. Asus was the only throwing a possible max for 24/7, that was in the range 1.4-1.427.
But other sources claim not to climb up after 1.38.
I don't know. Maybe we are chasing ghost here.

That's generally used when talking about two of the same chip. IE. comparing two Q6600's. It's obvious that two differently designed CPUs on a different fab process are different.

Still, that doesn't mean that 1.46 is long term safe for a 2500K.
