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.
Liquid Nitrogen? Compressors? Huge heatsinks? Wouldn't it have been cheaper just to beowulf cluster a few systems together?
Then again, I guess that wouldn't be as 1337, and we wouldn't have this slashdot story over it.
they should have pored it on good ol' Tom and then put a hammer to him to see if he'd break into little pieces.
relax im kidding.
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*
Surley there is a limit here? Plus, doesn't this remind you of that /. article about the person who put four compressor coolers in his computer?
:D
I wonder what they could OC a Graphics card to if they cooled that down with Liquid Nitrogen...

What's their excuse?!
When did overclocking become a sport? I thought it was just a way to save a few bucks on a processor. Or rather, waste a few bucks if you're unlucky.

Sounds like it could hurt you and your equipment pretty easily. Better not spring a leak!
cool... *drools*
but.... uhhh... how many people have liquid nitrogen at their house, and what exactly the cost of keeping this baby going?
i dunno, i just don't see a point in having this much processing power in a home computer, and there are much better (safer, surer) ways of cooling mission-critical computers. I know that at Nasa Ames they use some type of nonconductive liquid and immerse the whole CPU in it, forgot what it was called though...

I would like to see the same thing done with an Analog-to-Digital converter. It would be fun to be able to direct sample a 2.4GHz WLAN signal!
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.
Looks like Slashdot has discovered Tom's Hardware Guide today.

Nice to see my two favorite sites (besides Google) linking to each other
Because it's not there.
The experiment to see if it can be done is always fun, but I wonder what practicality can come out of this? It's expensive as can be and equipment lifetime costs are high due to frequent failures. I've done some overclocking in my time, but it has always been sort of a hobby thing to see if I could do it. Several years ago I was impressed when I actually got to visit a couple of Cray clusters we had been submitting work to. They had little windows on the ends where you could see liquid (fluorocarbons) flowing over the components to keep things cool, but this was a multi-million dollar facility doing classified work.
I guess I am wondering if there are there any users seriously pushing the limits of commodity hardware by overclocking to extremes?

I wonder if this would be cheaper for short render work than purchasing a faster CPU.
It would be neat if they had blade servers that had a liquid nitrogen tanks. When a work order is recieved, a truck comes in and fills a liquid nitrogen storage tank. Then it's fed into the blade cabinet. Once all the cpu's in the blade are at running overclock tempature turn the whole thing on.
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.

...a liquid oxygen cooler is smoking!
It seems like liquid nitrogen is overkill. If the processor was running at -190 Celcius, it means that there was a lot of room for the processor to go. If the processor's normal operating range was something like 40 Celcius, then couldn't they have used something else less drastic, that would cool the processor down to just around 40? It seems like they didn't need to get the processor down to -190 or was nitrogen used just for the theatrical value?
This has been done before though along other lines: http://www.muropaketti.com/artikkelit/cooling/r300 _ln2/
imagine a beowulf cluster of those...
(sorry i just had to)
This is cool, the old CRAY used to use something like this but I think it was freon , What I want to know is what would happen if you cooled the ENTIRE MB ? Memory and all ? Could you pull 10+ gHz ?
FP!
hmm, maybe i should get one of these. My processor is kinda slow...

some fool will try to rig this at home, as clumbsy as we all are, not to mention how painful it is to work inside a system, and will end up spilling liquid nitro and breaking a couple of fingers into pretty little frozen shards...I won't touch this one with a ten foot stick.
I'm not sure, but a better use of industrial gases might be this and probably would provide more perceived results.
(speaking as an ex LOX, LH2 and LN2 piping designer, of course, YMMV)
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).
I love how all they are wearing in those pictures are goggles. And are they performing this "record breaking" over clock on the walkway in an apartment complex? Toms crew though of everything to get it to 5ghz but very little on safety.
Looks like they're half way to an X-Prize.
...even something that powerful cannot withstand the almighty slashdotting forever
they suffocate. Natural selection, I really don't foresee a problem.
With all that fancy talk about tolerances and only one company in the world that could make the aparatus, you'd think it would be bit fancier... Nope, just a coper plate with a copper tube sticking up off of it that you fill with nitrogen, and it cools via evaperation. I could build it with some 2-inch copper pipe, a torch, and some soldier... 5 GHz is cool and all, but come on, is there really the need to make it sound so difficult?
If they're going to push the limit and using liquid nitrogen anyway, might as well do something potentially useful.

This overclocking stuff is REALLY stupid to the point of insanity. My conclusion is that it's a weird fantasy about the lone DIY (do-it-yourself) tinkerer.
First, consider the economic side. For all of the special efforts and costs needed to cool down, test, and monitor an overclocked CPU, you could just buy a couple more for the same speedup effect. No special anything required. At the same time, there is no real need for all those cycles--we have a glut of cycles now. If it were really cost-effective to overclock and use special cooling systems, then the very few people who actually do need lots and lots of cycles would be using overclocking for their supercomputers--and they don't. They just buy more CPUs and run them the way they were designed.
The design question leads to the second point. Building a modern CPU is not a hobby for amateurs. It is an incredibly complicated device involving the efforts of large teams of very clever people using very fancy design tools. No one person could even know all the details of a modern CPU. Far too many details. They may know some of the higher level features, or know a lot of detail about a tiny section, but no one really understands all of it. However, they are doing the best they can to insure that it will work reliably, and that includes MANY design considerations that are related to the clock speed.
So back to my main conclusion: Overclocking is a fantasy of the DIY tinkerer "beating" the experts. Actually, it's nice when it happens, but overclocking is NOT one of those cases. The overclockers fantacize about some form of "delivering more bang for the buck", but they are competing directly against professionals with the same goal. The pros win, especially in Intel's case where their development costs per CPU are almost negligible. As the joke goes, "The race is not always to the swift, nor the battle to the strong, but that's the way to bet." The overclockers already lost. (By the way, I think this is also an expecially American fantasy, a kind of "independence" thing, and that there are very few non-American overclockers.)
One more technical aspect as a fairly concrete example. Overclocked computers can become unreliable. Many overclockers limit their testing to "Does it boot and seem to run the OS properly?" However, the OS is not using the floating point resources the same way that true numeric applications do. The machine may seem okay as far as the OS is concerned, but actually be producing gibberish results. (There was actually a probable example of this published by seti@home. I'm tempted to diverge into the psychological relationships there...)
Ergo, I've never heard of Intel hiring someone for their expertise in overclocking, and I don't expect to.
Freedom = (Meaningful - Coerced) Choice != (Speech | Beer^2), and sad sock puppets' bad mods avail them naught.
The point of this is to see how fast you can overclock a normal processor using any means necessary. Says nothing about survivability of components, only the maximum stable (over ~6 hours) overclock reached. Think of it as a practical exercise.

Dear Slashdot Reader:
Thank you for pointing out to us the dangers of condensation. We have taken steps to address this problem.

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...
Where are the usual pretty Tom's Hardware graphs? What the hell is a 5.25 GHz processor good for, if we can't awe over benchmarks like "time it takes to process a SETI unit" or its score in Sandra 2004?
That is the stupidest way to use liquid nitrogen. all you would need to do is use a small dropping utility. (very thin pipe and drop it onto a copper heatsink the nitrogen will vaporize and remove the proper heat, if you need more cooling then you give it a larger amount of nitrogen. it looks like they way over cooled the thing and they probably destroyed the mother board, its freaks like this that give geeks a bad name. but my real question is, why did they use a crappy Intel processor. why not a power 4 or a p970, or spark processor. those processor's are designed to scale and are built better. you could probably get 6 or 7 GHZ on a p970.
I keep finding myself wondering whether such extreme temperatures won't cause motherboards, surface mount components, and the like, to crack?
But more than that, I find myself wondering about the futility of it all. Why do people devote so much time to overclocking, building replicas of things that are obsolete, or making things from scratch that whole R&D firms have worked on perfecting for less money. There's plenty of new things to invent / develop. Show some creativity, guys.
Could it be that there's some practical point in overclocking? Maybe the mathematicians will tell us that there are some problems that can only really be solved by a really fast processor (i.e. can't readily be broken down into a task that multiple processors can tackle). If the Army secretly overclocks in order to break codes faster, I'd be interested. Otherwise....

According to a mechanic I once knew, the tranny on a VW beetle will bolt directly up to the engine from a Porsche 928. He claimed to have done this once, and the vehicle made it 50 whole miles before all the oil came out the bottom (but it ran like a bat out of hell for those 50 miles, since a VW beetle weighs ~1500 lb compared to ~4500 lb for a Porsche 928). Oh, and it was a *bit* hard on the suspension, and they had to cut a hole in the rear hood for the engine to stick out...

It was not the intent of the people when they built roads to be driven on at speeds exceeding 55MPH.
In other words, stop being lame, it's a hobby, people like to tinker see what their gadgets can do.
They're not using these in serious scientific research so why do you care so much what they do?
I had a science teacher do this once, but with breakfast sausage links in the fingers of the latex glove. A very effective demonstration! I thought something was strange when he turned around and had his back face the students when he put on the glove.
I can't wait for the posters:
"Yeah but why would anyone need 5GHz??? That's way too much, I get by with my 286/386/PentiumI/II/III/IBM PCjr and anyone who gets something faster is wasting their money."

Less Talk, More Beer.
a lot of programs either dont make use of smp or use it very poorly for any number of reasons
I'm well aware of that. I've been enjoying personal homebrew SMP rigs since the days of the P1. My approach has always been if you want it done properly do it yourself. Support has been improving, especially of late.
Even without programs that intelligently distribute load across the CPUs, you can still use processor affinity to restrict one of the SMP-unaware processes to a single CPU, maxing it out, while you enjoy gaming (or whatever) on the other CPU(s).
Really, no matter how fast you think your current CPU is, in a multitasking modern OS you would probably get abetter computing experience (less lag, reduced thrashing, smoother playback) with two (or more) slower CPUs taking up the slack.
I have an old dual P3 1GHz that still gives me a smoother ride than my P4 3.2 GHz in work. If I was single-tasking, like running a demanding game exclusively, then that newer P4 is probably going to win out - but in that case I'd rather use a console, frankly. YMMV.

So they couldn't get the last 15% out of it, because memory had to run in asynchronous mode, because the (bus?) clock multiplier wouldn't work with the actual memory speed?
Do you have to be careful about this when you are building your own system? How many systems out there are running 15% under spec, just because some multiplier is wrong?
Can someone please explain how to choose speeds for DDR memory, FSB, and CPU, so this doesn't happen?
They also mentioned that it was because the memory was running at a latency of 3T. What difference does that make to having to run in asynch mode?
How do you even know if you're running in asynch mode?
Thanks for any info...
Didn't a group of people push processor limits to the max a while ago with liquid nitrogen too?
Pelé!
Overclocking is nice, my Cyrix running at 233 is overclocked to 266 Mhz, too. But with the money spend in things like Liquid Nitrogen, and the older CPU, they can buy a SMP motherboard and 2 P4 at 2 Ghz or more. Almost it is the case in The Argentina. But, it's c00l to overclock for testing, or if you don't have the money to buy a new CPU

That was the genius of Zollar's setup. There was a waist high table in the front of the lecture hall for doing the demonstrations. So for him to be behind there and fiddeling with stuff with his hands where no one could see them, would have been totally natural.
This is basically dumping liquid nitrogen onto processors outside and clocking them up. There's not much of an achivement there. You can soak LEDs in liquid nitrogen and make them do all sorts of interesting tricks too. Whoop.
Why not wait until someone comes up with a indoor version, properly vented and pumped, with a compressor cycle that you can actually use on a long-term basis? That would be an achivement I'd like to see. Of course, it's orders of magnitude more difficult and dangerous, too.
..don't panic
jsut thought id point out that at the end of the article, in one line, it states that the system was only fully stable at 4700MHz. 5.25GHz crashed all over the place this isnt all that remarkable.
I remember years ago it was always talked about using Liquid Nitrogen to cool CPUs and it was like the one thing that a person could do that would be considered by the entire community as "wow." I mean if you could overclock that little 233mhz AMD up to 500 or so by sticking some liquid nitrogen AND figure out a way to keep all of the condensation problems away it was pretty cool. Now a days thoes problems have all been solved and Liquid Nitrogen is cheap. Now on to Beowulf, the term beowulf means very little, and it would be more accurate to just call it a cluster rather than a "beowulf cluster". At least thats from my experience in clustering.

When they figure out how to overclock the human brain, let me know.
It is well known that single crystal, isotopically pure diamond makes the best heatsink material, as this substance has the highest thermal conductivity of any known material. Engagement cpu anyone ?
A lot of people have asked about the relevance of this: Basically, there is none. But that's all right. It's a nice story to entertain their readers, and I'm willing to bet it was a lot of fun for them, too. Not everything needs to have a point, you know.
That said, there's one thing that would still interest me: Now that we've seen them overclock that wimpy Pentium 4 (I hate that architecture! How can anyone build a 20-step pipeline?), let's have some real techno-porn: Liquid Nitrogen-cooled 2x2.0GHz G5 Powermac! That would be quite a sight to behold. Especially with that nifty 1Ghz FSB.
Divide et impera!
You must never have read Tom's Hardware before. *EVERYTHING* they do is played up to man-on-the-moon levels, regardless of how trivial. You can either get used to it, or do like me and simply avoid Tom's as much as possible. :)
Another blah blah blah article. Anyway, I sometime spend time on blah blah blah things, and noticed that the CPU-Z 'screenshot' in the video, had the original P4 GHz-rating ghosted out. I don't understand- what's so secret about the GHz it was rated for by Intel?
Since it's Tom's Hardware, I have a tendency to believe that something fishy is going on.
I overclocked for two years on Ritalin.
Pull my finger for my public key.
So are these commercially available, for the cost of a regular CPU (eg Athlon 2500+), have warranties and take up the same size in general?
If not then who fscking cares really? Sure its cool they have that much power. But then again look at those big G5 clusters.
Good one. The only other professor grosses-out students tale I know of is licking pee from a finger.
Liquid Nitrogen is cold when it's evaporating. You want it to be cold? Give it a flat surface to evaporate on, and keep pouring on the Nitrogen.
Basically, if you lay a piece of Saran Wrap on your motherboard, then let the LN2 drip on the CPU constantly, you can cool that bastard to -195.798C.
Making a big, tall tower just looks like a stupid Freudian mistake.
Sorry Germans. No wonder they've lost every war they ever started.
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.

"Give orange me give eat orange me eat orange give me eat orange give me you." -Nim Chimpsky
and why the copper pipe? If all you are really concerned with is putting LN2 on the cpu, just use a plastic pipe and seal it well at the bottom. It seems counterproductive to have good thermal conductivity through the thickness of the pipe...
Unless maybe their pipe has a bottom to it, but that seems wrong as well. Seems to me that the heat would cause N2 cavitation at the bottom of the bath and reduce the efficiency of the cooling. I am not a refrigeration engineer, but this seems like it is hillbilly engineering to me.

How did they prevent condensation from forming on the hardware? It sounds like the air would be humid enough.
The blocked-out part you mention is where the model of the processor would normally live (i.e. the Mhz for intel cpus and the rating for AMDs). See here
The article does raise an interesting point in my eyes.. Modern Processors put out too much heat!
I'm wondering when Intel and AMD will stop concentrating on speed (as at some point it may become less relevent, but not quite yet I guess) and start concentrating on lessening the heat generation.
I for one pray for the day that even passive cooling becomes enough to run a pentium....
As a side note to that, Via has managed to make processors that can be passively cooled, but they're much slower and equivalent to a P3.

That he used way too much thermal grease.
Hell, i bet you he could've dropped the temperature even more by making that layer not as thick.
I'm adding this to my pr0n playlist. J/K, I don't have one but this is so awsome. I can't help but wondering how much it would cost to maintain that speed/temp with liquid nitrogen. It's kinda like the nuke-sub movies where the core reactor needs to be cooled but it leaks and over heats. Are we going to be seeing the same thing is super computing soon?

"People who do stupid things with hazardous materials often die." -- Jim Davidson on alt.folklore.urban
umm... So they are claiming a 5,25 GHz overclock, but it wasnt stable at that speed? Then i'd hardly call it a real overclock, I could propably clock my P4 to 5GHz too but it wouldn't work for more than a few microseconds. If they want to claim that kind of results they better show some long running stresstest/benchmark results too. And why is the stock clockspeed of the CPU covered in all the pics?
I never thought I'd see the day that shit would run faster when you froze it.
YES!!! I DONT EVEN HAVE TO FINISH! You already know!
abcdeghjijklamenessfiltersuxyz
All that work to go from 4 to 5 Ghz? Just seems a complete waste of time. They'll be comeing out with the 10Ghz in a few months. Besides, will you really see any speed difference? You not likely to say, "OH my God! My computer is just blazing now! Its the greatest mod ever accomplished!" Double the speeds, otherwise its just sillyness.
After seeing the clock rate they got, I really wanted to see the benchmark results. Do the numbers scale linearly from 3GHz?
Just an FYI, the boys in Japan have had a 5+ghz stable p4 since March.
http://son.t-next.com/
THG likes to say they do everything first, when in fact their p4 wasn't even stable at 5ghz. only 4.7ghz.
And yes. It is excessive.

What does this mean:
Before we got down to our actual record attempt, we checked the loading capacity of the materials and individual components. To do this, we placed the entire test construction in a polystyrene shell and installed it. ( source)
I don't get the part about testing the loading capacity. What is that? And how do you test it by placing in in polystyrene?

Yeah, never improve on any existing design. Just scrap it and buy something new. God forbid you ever upgrade your video card...
;0). German cars have been coasting on reputation for years now. There really hasn't been much inovation there.
The gearhead crowd is much maligined here (think primitive geek), and perhaps they deserve it (C-West wing on an Accord? oh puleeze), but some also race (err, SCCA). That rice burner may fit race restrictions better than a Beemer (not to mention the early Civics had a wishbone suspension. Something a BMW could only dream of in that price range).
Better car as determined by whom? Yup, the NSX, WRX, Lancer, Skyline, RX-7, and 300Z were all just crap
When I had to commute through a moutain pass, I would regularly pass Porsches, BMWs, and a few Audis. My car was a fairly stock Subaru GL. I doubt the Porsches ever saw 60MPH in their lifetime. Not that I was going very fast, but I didn't have a year's salary swishing through the countryside. It's nice when you can actually enjoy the car.
Can I assume you are fairly ignorant about automobiles or just shallow?
From the article: > In plain English: 84 watts on a surface of 1.12 > square centimeters - the size of a fingertip! > Extrapolated to square meters that make 840,000 > watts or 840 kW. Not exactly true. The true number is 10000 / 1.12 * 84 = 750 KW
Have you even read the benchmarks THG between the P4 and the Athlon XP 64/64 FX they did after it was released? They show how well the Athlon 64 chips do against the higher-clocked P4's, and consistenly recommend AMD's as more bang for your buck.
Are you talking about this article?: AMD's Athlon 64 Has Arrived: the Athlon 64 FX and Athlon 64 (and Intel's P4 Extreme) Reviewed
First, there's no mention of "more bang for your buck" in said article.
And while they do "show how well the Athlon 64 chips do against the higher-clocked P4's", they summarize it as such:
"Summary: The P4 3.2 EE wins 32 times, the Athlon 64 FX-51 15 times - an uncertain 64-bit future for AMD"
It reads like they're heralding AMD's demise!
This gag was done on St. Elsewhere. Doctor Ehrlich (Ed Begley, Jr.) demonstrates the taste test by dipping his finger in a sample. Then the senior Doctor Craig (Mark Daniels) says "nonsense!" and grabs the flask and dips his finger in the sample, tasting it himself.
Then Doctor Ehrlich, horrified by the result of his prank, admits, "Whoa! I switched fingers. I thought you knew."
That was a funny scene, but then most of the Ehrlich/Craig scenes were pretty funny.

So you never rip DVDs, convert DIVXs (or other CPU-intensive tasks), convert music files from mp3 into something else, do transcoding to fit mp3s onto smaller devices, or play games that want to grab an entire CPU?

Awesome effort by the THG folks! The equipment used by Sun and Intel for engineering characterization of these die is similar, but uses 3M Floronet and only goes to -40C. If they go use Liquid Helium, they would get closer to absolute zero, but Liquid Helium is more expensive (Helium is a rarer gas than N2). If only we had some Bose Einstein Condensate from Boulder Colorado (The Nobel Prize winner is there), we could cool the processor down to a few nano-Kelvin. -- Ross

I read a bit about him a few different sites. Sounds like an interesting guy.
Don't anthropomorphize computers, they don't like it.
