Yeah I'm sure it is correct, probably using Ln2 or something, I have seen a CPU-Z with someone having one stable at 7.1 GHz on Ln2.

JacobF recent upgraded his system with an Ivy and using a "phase change" cooler, got it as high as 5.7GHz (see Z77/Z75 subform).  Most of those units cool between -30 and -50 Centigrade (of course they can cost $1000).  There is no need for the -190 range of liquid nitrogen (which barely last a couple hours by the time the liquid evaporates).
 
If hobby, be practical on what you can achieve.  A liquid chiller should be able to reach upper 5GHz too, assuming you had a good FPO batch to begin with.

You are incorrect there Lehpron, Ivy Bridge scales very very well with cold and voltage. Ivy for the most part has no cold bug, so it is really opened up when below 100C.

In that bold, I wasn't talking about Ivy Bridge, I was talking about the cryogenic liquid's ability to last.
 
That said, if JacobF can approach 6GHz within phase, then once someone reaches similar temperature range, that frequency range is within reach.
 
As for how Ivy scales at extreme low temps, I'm not too convinced we're looking at a capability of the process lithography or architecture.  I detailed it out a while ago, but 32nm Westmere Clarkdales and Gulftowns have reached 7GHz before.  Therefore, 32nm Sandy Bridge quads should have also been able to, but castrated due to Intel's 57x multiplier maximum and sensitive 100MHz strap, most had a hard time approaching 6GHz.  All record runs of Ivy Bridge happen to have higher straps of around 110MHz (since clock generator is in the southbridge chipset) and Intel bothered to raise the max multi to 63x, therefore 110 x 63 = 6.9GHz-- making 7GHz a matter of raising the sensitive strap frequency.
 
In otherwords the supposed scalability is artificial (it's fake); we're only looking at Intel relaxing restrictions with Ivy versus Sandy.  I'm sure the Ivy Bridge processors are capable of 8GHz, but Intel won't let it happen.
 
It is odd that while LGA2011 can boot with the 125MHz strap at relatively lower frequencies that air/water can reach, not at much higher frequencies.  At least all record runs keep the range of 100-105Mhz while running into the max multiplier restriction.  Of course sometimes I wonder, since the clock generator is in the southbridge, why not chill it too with the CPU?  Then LGA2011 may finally reach 7GHz too if 125Mhz was stable (125 x 57 = 7.1GHz).  Gulftown did it, so it isn't a TDP issue or lithography issue.
 
It's the southbridge; at least I'm certain every record run depends on its ability to raise beyond 100MHz and I have no doubt in my mind the processor can take the maximum multiplier.

I'm not arguing the limitations, because I agree with you, in that both Sandy and Ivy Bridge have been castrated.
 
I was trying to get at, that Ivy Bridge scales frequency to temperatures very well, otherwise there could be record runs at only dry ice temperatures, or ~-78C. At around 0C, expected frequency should be ~5000-5500MHz. At -50C, expect ~5500-5900, at -100C and below, then the 6GHz plus range is wide open. This is what I was getting at when I said they scale very well with cold, meaning they have much more potential at -196C for example, compared to say, -50C.
 
Whereas Sandy Bridge chips could do anywhere from 5000-5500 on just water, and 5500-6000 on something as warm as a -50C phase unit. I should have said "Ivy scales much better with cold than Sandy", but alas. 
 
That is also a very good thought with the southbridge.. If I had a LGA 2011 board, CPU and RAM I would spend the money to get some pots and LN2 to test it for you. I've been thinking hard about getting LN2 gear and benching my 1366 stuff, then selling the 1366 and getting an Ivy Bridge setup, so if that were to happen I'll try cooling the southbridge as well.
