Max voltage i7 860

At 3.8ghz its 1.272 volts. For 4ghz its 1.4 volts. Max is up to you, Kabooooom!
a general rule of thumb is no higher than 1.4 with pretty much all CPU's unless you plan using some pretty extreme cooling
1.4V is this highest stock voltage Intel are prepared to sell one at. As such many people consider this the safe limit.
Note that the actual voltage limit for a given lifespan depends on temperatures and your particular processors' current draw as a function of voltage. No idea what entireweb is going on about.

What do you mean "no idea". I gave the exact voltages required for a given overclock on i7 860. I also said there is no maximum voltage. You can apply what ever you want.
Also pray tell, what has temperature, current draw and voltage got to do with lifespan? I presume you are confused with another technology known as the lightbulb!
Are you telling me LOL, that you are going to wear away your processor by increasing the voltage and current draw (within spec)?
Oh yes, prey tell your technical thesis on this. And BTW no WIKI quotes on alleged electron migration etc.

At best you gave the voltages your processor requires. Every processor is different, what your chip needs means very little with regards to what other ones need. All you've done is demonstrate that you don't understand this.
Lifespan is a function of temperature and current, current is a function of voltage. That you fail to understand Black's equation does not make it incorrect.

Voltages are never a standard setting on any setup, ive often seen people asking for overclock settings from others to try and clock their own rigs. Im of the school of thought of starting at a low clock, get it stable and then work from that basis, it takes a bit longer but its worth it in the end, its a great way of finding lower voltages you can run at with your own kit.
Jon, do you mind if i ask, whats the max voltage youve run on your corsair ram, and does the gigabyte x58 boards offer votage increases in single steps, ie 1.64-1.65, my asus p6t only offers increases of 0.02v per key stroke in the bios, curious to know if other boards do it differently?
My ud5 offers the same increments, so it's either 1.64 or 1.66V. However I believe this voltage droops, and when measured under load 1.66V actually comes out at 1.65V. I don't remember which board this applied to specifically, and haven't taken a multimeter to mine yet.
I think, though I'm quite hungover and can't remember the source, that triple channel ddr3 can be used at 1.8V in a dual channel board. The 1.65V limit is for fear of hurting the imc. I'm running at 1.66V at present, the extent to which exceeding this is wise probably depends on temperature. If the ram clocks higher with more voltage I'll go up to 1.7, perhaps 1.75. However I've not got around to lapping the processor/block yet so it's hotter than I hope it will be.
Wonder if there's a thread on xs about this, I think there's a qpi graveyard but not sure if there's a vdimm one. Here, suggests that the chips will cope with just about anything, though this is in the opinion of XS.
Cheers

There's no such thing as an exact voltage for an overclock, as every chip is not the same and have different VIDs. Many people are getting stable 4GHz clocks at less than 1.4v.
I also think you need to calm it down a little bit matey, before you get a holiday, there really is no need for the angry childish outbursts
