(as long as temps are under control) That's not to say pumping voltage to the limits is practical at all, increasing clock speed will increase heat and power consumption in a linear fashion. However, increasing voltage usually increases the two in an exponential fashion, so it's simply more practical to run at the lowest stable voltage for your target overclock.
Not quite linearly actually, as when you increase the amount of voltage going through the chip, you increase the amount of parasitic capacitance and inductance with the chip and its external pins (what we see). You get too much build up of this and it can kill a chip or cause clocks to be unstable.. That said its typically low enough that it's not noticeable unless its mapped over years of the chip, just saying that's the other reason.

Someone send me the the hardware and I'll make it fold for the team at whatever voltage we would agree on.....

The thing is though, with pushing the voltage so high you get diminishing returns on your overclock. To the point where 1.4 vs 1.53 will net you no appriciated gain giving the cooling sceme. Plus the higher the thermal load that isn't disipated (using the Noctua) the more electrical resistance. You start having to push beyond 1.53 on the board side to actually get 1.53 on the chip side , and that will stress any board out. Sure, the chip might not fail. But I bet you will start killing all the boards for no good reason.

I won't run my PSU beyond 80%, I would push my voltage to that threshold either out of personal preference.

Seconded! Send your hardware to Peri.........

only 1.4v lol

my cpu needs 1.42v for 5.0 24/7

its not just the juice its in combination with the speed
some people been runing 1.5 for 6 months no degradation n some 1.4 n have degradation


i seen people pump in over 1.7v+ n the cpu still alive
i'm chicken i only pumped in 1.6v for some tests

if you cant keep her cool dont pump the volts

Voltage wussy? I was putting 1.49v through a e8600 back in the day.

Thing is now with chips like the Sandybridge using a lot of voltage is really unecessary unless your TRYING to blow up your chip or see its max potential. But most of us around here know that there is only so much benefit to overclocking before there isn't any more gains and that is when most of us stop.

There are a couple of other forums where this has been done, more than once. Suicide runs, peltier cooling, etc. Lots of reports of degradation, as in, 'my chip would run 5.1 (or 5.2 or 5.3) then I went for more and now it will only run 4.X'. It seems pretty rare that they run at 5.0 24/7, whether that is due to lack of cooling hardware or lack of how to knowledge. 4.8 24/7 is a lot more common, and a kazillion are being run at 4.5. The biggest source of data (that I have found) is overclock.net.

This. As will all things overclocking, YMMV.

BTW, I *loved* the thread title!

yup lol

personally i go subzero for over 1.5v

so many of my cpus are good for 5.0+ stable i wonder how high op clockin lol
and how much gear he blew up lol
