Sandy Bridge maximum vcore for 24/7 use

[Movieman]

Listen to the manufacturers. It's funny how people just come out with all sort of "max number" for each voltages without any proof. It was CPU PPL for 65nm and 45nm CPUs and the next was max i7 vCore and so on. Many experienced OCers proved them wrong by going really high values for months with any degradation with countless setups. Each major manufacturer has their lab and they have far better grasp and knowledge than average joes who blindly state numbers such as 1.35 as "max". Asus and Intel said if you go over 1.55, you'll start to see some degradation.

It's your choice to be over-cautious but just remember this, between 65nm, 45nm, and 32nm, there aren't any differences in max vCore recommendation from Intel. nm differences can't be measured by mere .01 volt.

I would respectfully disagree. I remember well when the first 45nm Yorkies came out and people treated then the same as the 65nm Kentsfields and we had a rash of dead chips on the forum.
1.4vcore with 1.45VTT killed those chips.
It wasn't one or the other but a combination of both.
The numbers I post are yes, suggestions but they are safe ones and for air cooling. The last thing I want to do is to give info to some guy and see him lose a chip or anything else.
Yes, I'm conservative but the numbers I posted will give you a solid 4600+MHz for 100% load 24/7 use and he did ask for 24/7 numbers.

Is that BIOS or load in windows?

Bios settings..
