i have an E8400 and im starting to overclock it, i was just wondering what the max voltage that should be put through a 45nm chip? my stock voltage is at 1.192v

And another question, if you overclock but get a decent cooler that keeps the temps down, the chip should last just as long, if you keep it at stock temps right, its the heat that screws them up isnt it, or high voltage?

Thanks

Personally on a chip that expensive (it's a high price for me), and considering what I've read so far, I wouldn't put it far over stock volts really.
A little, but not much.
 
Looking at the other thread about degradation looks like <1.4V should be safe but no one knows for sure. I'd try to see how much it will clock on stock first then decide how much volt you gonna put through it.
 
well, i put the fsb up to 350 on stock volts and it was stable, then i put it up to 355, when i booted into windows the voltage had gone from 1.192 to 1.3, it was still on Auto in the bios so i went back in there and manually set it to 1.19375 which was the closest to my stock volts, now i run cpu z and get the following:

355 fsb

3.2 GHZ clock speed

1.16 volts

Its gone down even tho i set it to 1.19, why is this?
 
cool, so my cpu is overclocked, under volted, and so performance gain and temperature decrease, excellent! im 2 degreess cooler at idle now :p

Its temperatures as well as volts remember.

Current is what damages processors AFAIK.

Eg.
40C @ 1.4V
50C @ 1.35V
60C @ 1.3V
Etc.

Yes, it isn't exactly like that.

But if someone can work out by how much CPU resistance changes during load states/increased V/temps etc.. but I think that would take a lot of time and effort :p

Personally, when I get one, 1.4V will be my max. (90nm = 1.6, 65 = 1.5, 45 = 1.4)
