:S
Auto = ON when Mobo detects OC.

1.4v is WAY too much!
You should need around 1.30v in CPUz under load.
That rise in Vcore from idle to load is not good for stability, if you need 1.3v to be stable, you need it at idle too, so you have to raise Vcore if you leave LLC On after finding the stable Vcore, like i showed in my examples. But that means excess Vcore and Heat at full load conditions.

vCore: LLC ON -
BISO = 1.387
Idle = 1.392
100% Load = 1.408

I ran a troture test for 30 mins and there were no problems, vCore is stable at this voltage but anything lower causes a BSOD...

Im going to leave the setup as it is as it is stable, the only way I could get a lower voltage would be to lower the FSB and I want to keep it at 4GHz

read carefully
That rise in Vcore from idle to load is not good for stability, if you need 1.3v to be stable, you need it at idle too, so you have to raise Vcore if you leave LLC On after finding the stable Vcore, like i showed in my examples. But that means excess Vcore and Heat at full load conditions.

You said "vCore is stable at this voltage", what voltage? I assume 1.408v.
Now let me ask you, Whats your idle Voltage? I assume less as you use LLC.
Are you stable when the CPu is under less intensive load but at the same frequency and the extra Voltage boost has not occured? No, You said "vCore is stable at this voltage" that is 1.408v, not 1.39v.

So raise Vcore until you have 1.408v at Idle in CPUz.

And afaik you have the worst i7 chip ever! 1.4v for 4Ghz is crazy.

ARGH! this makes no sence... norcaljason, a guy who posted earlier in theis thread, had 4GHz with the i7 870 and his vCore is at 1.28v
why the hell do I need 1.4v for my vCore to be stable???
anyway im set at 1.4v for idle, thnx for ur help jasjeet

Try lowering your Vcore and tell us what you get.

Yep, all chips are different.

My specific chip doesn't need much voltage to be stable. BUT, it's very hot.

Running LinX after 10 mins I peak at 90deg.

I'm not voltage limited, I'm heat limited.
