Stock voltage for E6400?

My E6400 does 3.2GHz (8x400) with no problem. (Pretty standard these days, I know).

CPUZ shows the VID as 1.320, the bios shows "normal voltage" as the same 1.320.

So, I went into the bios, disabled all the automatic voltage regulation settings, hard set the voltage to 1.320 and here I am.

I just started Priming (we'll see what happens over the next 24 hours).

I want to know if 1.320v is the normal, stock voltage for an E6400? Assuming it passes Prime, I assume I should I set the voltage LOWER if possible, right?
 
There's no set stock vcore.

Intel's whitepapers specify that stock is anywhere from below 1V to max 1.3625V at defaults.

That's precisely the kind of answer I was looking for. I actually searched on Intel's main page for "E6400 voltage" and got a bunch of crap answers. When will these multi-billion dollar corporations actually have a search function that works? :roll:

Thanks, N7. We'll see what happens w/Prime95 overnight.
 
My e6400 defaults to 1.325v so you're in the same ballpark. I have mine set to 1.350v in the bios (actual reads 1.335v) and it too is stable at 3.2Ghz. I could probably lower the vcore to default, but since loaded temps are in the low 40's (42c & 43c) I don't really see much need to mess with it.
 
Thanks acruxksa. Are you measuring your CPU temps with the EasyTune5 program or are you using Intel TAT or CoreTemp (same thing, essentially?)

I'm using TAT, and I have an AC Freezer7 HSF and I get 57C load temps. EasyTune reports 47C, but that's the CPU socket temp and not the on-die temp.
 
Intel doesn't list a stock voltage because voltage and CPU frequency are adjusted on the fly when you have speed step enabled.
