Pushing P4 to 5.25GHz with Liquid Nitrogen
SkywalkerOS8 writes "The folks at Tom's Hardware have an article up about their attempt to overclock a Pentium 4 over 5 GHz using liquid nitrogen as cooling. A DivX video is available along with pictures of the custom copper cooling head they made."
I think they should have splashed some nitrogen on some of those flash ads. Gives me a headcahe just looking at the main page.
Also makes my Thinkpad screech to a crawl.
Oh well, I bet it'll get really good time in Seti.
Treehugger? Treehugger... Treehugger!
reading things like these I'm reminded of the good old days where all you had to do was getting two 333MHz celerons, overclock them to 500MHz by upping the FSB, some socket-to-slot adaptors and *baddabing* you had a total of 1GHz for a bargain while using normals coolers. Was that only 3 or 4 years ago? *sigh*
In other news...
A rose achieved 3.7GHz and a segment of rubber hose was clocked to 7.5GHz. A red rubber ball, however was unable to surpass 300 MHz befor shattering.

The question is, how fast did it play solitaire once Windoze was booted?

I have an Athlon that seems to be growing warts. Will this take care of that as well?
Custom copper cooling head? That's a bong if I've ever seen one.
This is a amusing article, but kind of misses the point. So one problem with running processors faster is that they get too hot and we can get around that by cooling it with liquid nitrogen. Cool, but CPU heat is just one design element contributing to the effective speed of the computer.
This is like saying that I should cool my VW with liquid nitrogen so that I can run the engine faster. Sure, I'll pick up some speed, but honestly there are lots of other factors preventing my VW from running at a more productive speed than how fast I can get the engine spinning. The shape (like the bus on a PC), the steering (peripherals), and mostly that the cops don't appreciate me going 328mph through the school zone.

Heh, this looks like a lot of fun, but that board's not going to last long. Look at the picture on the first page. See the capacitors next to the socket with little ice crystals growing on them? Those are electrolytic caps; they use a liquid electrolyte which doesn't take kindly to being frozen solid. I'm amazed they didn't split open. Colder isn't always better; some components will simply fail at liquid-N2 temperatures. At least they took steps to deal with condensation.
"Wild" Bill Zollar, my Chem 140 professor told us the story about how ever couple or four years he'd do a liquid nitrogen demonstration. The common freeze it break it variety, which he personally didn't find exciting enough to suit his tastes. So he'd don two latex gloves having filled up the thumb of one with ground beef. He would then dunk the thumb of ground round into the liquid nitrogen while he was talking and then take it out and hit it with a hammer. Appearently, the last year he did it, a chuck of his flash frozen fake finger hit a girl in the head, causing her to pass out! Which in turn got HIM sent to the dean's office, and why he couldn't do it for us, and hasn't done it since.
Or so the story went (as I recall).
Its a true screenshot. What isn't true is the actual clock... I ran some ASM that had a typo in it, and it somehow accelerated the windows timer, thus making apps see my CPU as something faster.
Even more amazing is what 3D mark 03 sees. Yes, to that program, I have a 60.1Ghz processor (not a typo)

And I didn't even have to use any more cooling than the laptops normal fan.
Any Questions? ;)

Dear Slashdot Reader:
Thank you for pointing out to us the dangers of condensation. We have taken steps to address this problem.
Instead of simply dehumidifying the air, in true Tom's Hardware Style(tm), our next overclocking attempt will take place in the vacuumn of space.
Sincerely,
Tom's Hardware

Only one or two, mind you, but it still boggles the mind that this Pentium running 2.5x faster than the Athlon chip didn't utterly dominate all comers.
Given the history of THG and their decidedly negative (some might say Intel-funded) view of the Athlon 64 chips, it's not particularly surprising they'd choose to pull that page, but it does cast further doubt on the continued relevance of what was once a high-quality tech reporting site.
The few posts questioning this on the THG forums seem to have disappeared in the time it took me to write this. Strange...

Whoah, time to lay off the meds. What do you care if someone wants to get all they can out of a product they bought?
Your post is a fine foil to dissuade someone from spending $500-$100 on OC'ing equipment. It fails miserably to describe why its bad for the average $25 heatsink buying OC'er. Hell the average Intel overclocker usually just uses the stock HSF. Do you really think you have a case when its so easy to take for example a P4 1.8 and overclock it to 2.4 with no extra money and no ill effects?
Your right overclocked computer can be unreliable, but that's why benchmark programs exist. If you can save $50-$75 by buying the lower end model and speeding it up what's wrong with that? I also don't really think your entitled to make the call whether someone has enough computing power as well. Am I allowed to tell you that you only need a '83 Yugo because YOU don't need anything more than 80hp?
These posts against overclocking never hold up and I don't know why you thought yours would.

I wonder if you can attach quad monitors, quad mice and keyboards, and have a lanparty on once CPU. I know the radeon 9800 can go that far and already does miltiple monitors, I know of X projects to use multiple USB mice simultaneously and possibly multiple USB keyboards too.

Hmm. Safety gloves? Protective glasses?
You can definitely tell that these are computer geeks, and not chemistry geeks. Liquid nitrogen is remarkably safe stuff to play with, unless you're deeply stupid about it.
