I have to agree with movieman.
I myself wasted hundreds of dollars degrading P4's (which were KNOWN to be very, very fragile), even running them as low as 1.625v on air. And everyone and their momma was saying that as long as you don't go higher than 1.7v (on air), you're fine. Yet just because *some* overclockers had no problems, many others had chips die or refuse to even work properly at stock or had degrading overclocks, even though the intel docs said ABSOLUTE MAXIMUM was 1.75v. So many people took absolute maximum to mean the same as max 24/7 air voltage...

And I remember how a few members on these forums (who don't post here anymore) mercilessly flamed and insulted me for being incompetent and stupid (when 1: I'm older than them, 2: I've been involved in this industry since 1994). And to make things worse, not only was I using high end air cooling (for the time) but also was not using any sort of vdroop mod.
People simply assume that just because THEY have no problems, that NO ONE ELSE will have problems either, and that's a common logical fallicy (That you usually learn about in school).

None of the people who insulted my "incompetence" offered to buy me another CPU. And it's very ironic that as the months went on, I was proven right by many other people who had these chips...others experienced degradation to various degrees as soon as they went over 1.55v.

I remember all too well what happened with the Yorkies. Dead chips, chips not stable at 3 ghz, refusing to POST in one board but posting in another...various things....and it always starts with 1 person claiming "omg it's safe", then another person trying the same settings and his chip dies...

I remember Benchzoner running yorks at 1.5vcore and 1.4 VTT 24/7 and not having them degrade or die, but that doens't mean that YOURS won't degrade or die...it's always YMMV, the instant you go out of specs.

And Movieman:
There were also people killing 980X's by treating them the same as D0 i7 920's...pumping 1.45v-1.5v into them and having them die...not many, of course..but it did happen...
