How 'Hardcore' Can you get with Liquid Nitrogen overclocking?

[Vanguarde]

What is the most absurd overclocking you guys have heard of? I assume it is running on liquid nitrogen, and perhaps is overclocked to 4ghz or more?

Links or pics would be awesome

Has that ever been tried? Sounds pretty crazy to me. Wouldn't that just wreck the cooling device?

I have heard rumors that some insane guy in Asia has claimed to have gotten the P4 2.53ghz northwood 'B' to over 5ghz with Liquid Nitrogen. Has anyone heard of this? ??

Yeah there's all sorts of good stuff like that - I don't have the link to the japanese site but my favorite is overclocking a system that is suspended/submerged in a non-conducting liquid:

LOL INSANE! 3M makes some crazy things

I love this stuff, anyone else have some more?

I believe it has been tried. (Can't remember where I saw it; too lazy to check Google right now.)

Big problem: different coefficients of thermal expansion for the metal (copper, gold, solder) and nonmetal (epoxy, ceramic, silicon) parts set up enormous stresses that can break connections and even the components themselves.

Secondary problem (but still big): condensation! I don't care whether you're living in Arizona, liquid N2 is waaay below the dew point.

Trivial problem: keeping yourself supplied with liquid N2 isn't easy, unless you're just going for a record.

I've seen it before. The websites are usually in japanese though....
