Ummm no, we are not making fun of him. Its geared more toward Intel being vague about their SB chips.

Any updates to this, or should we still stay at 1.385v till then ?

Was there any real need to necro this?

And the maximum safe voltage IS* 1.38-1.39v.
I have proof now.

What's the maximum VID?

1.52v.
Now, set that in your BIOS, with a reasonable overclock (at least 4.5 ghz at the minimum), do NOT use loadline calibration, and then run Prime 95 small FFT's (not blend) or Linpack with AVX extensions (requires SP1), and then tell me what the vcore reads....

(Hint: The max VID assumes you are NOT using loadline calibration, which goes out of official specs).

I'm not taking credit for that--it was some other poster yesterday who mentioned this....but I can't find where it was...it was in one of the 2600k threads....

I guess its better to just start a new thread and ask the same question instead of just reviving an old thread for updated information, sorry I was such a bother and have offended you by upping your thread. I'll keep that in mind next time.

I've set my bios voltage to 1.5200v w/o LLC I get 1.500v idle and 1.404v loaded in both CPU-Z and DMM.

Thanks for the confirmation, that info was not really readily available anywhere to me.

As far as I know, it has nothing to do with voltage levels, but rather the byproduct of increased voltage, aka heat. Come on guys, this is basic physics 101. The only real VID range that would exist in the SB CPU's, particularly the unlocked "K" series chips, would be a min/max voltage limit that would be designed into the chip. If this is the case, then their K series processors were not technically "unlocked, so they falsely advertised that.

Like I said before, people think that too much voltage will cause some sort of failure purely because of the voltage, which is simply not true. Thus, these processors should have no problems running at any voltage level, granted they are able to keep temps within hardware-safe levels. So I'm confused why there is so much attention placed on voltage, rather than temp. Two Core i7 2600k processors in the same rig setups are nevertheless going to produce different temps at the same voltage levels, so I don't see how it would be feasible to gauge CPU capabilities based specifically and solely on voltage levels....

You didn't offend me. It's just better to start a new thread when topics are that old. Now if a forum is pretty inactive (e.g. a few posts each week), then that's different. Besides, I was clearly wrong in my original post anyway, and now it just makes me feel more wrong since i tried to sound like a genius in the OP, which clearly I am not. Since there I never took into account that LLC was NEVER intended to be used "officially", so 1.52v w/o LLC becomes around 1.4v'ish.

The person who is the real genius is the one who mentioned that Max VID Was supposed to be used with LLC to get the real voltage....

On mine, its 1.392v if I set 1.52v in BIOS at full load (which, since the vcore is read in 0.012v increments with the sensors, could be anywhere between 1.385v-1.398v of real vcore). It's 1.476v at idle. That's a MASSIVE vdroop, though....0.080v droop just from idle to load...
