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.

Copid (137416) | more than 10 years ago | (#7840421)

There sure is. You're limited by how fast your signal can propagate through the gates and by how much heat your dissipate (power is proportional to clock frequency for any given IC, IIRC). Liquid nitrogen sure helps, but something will give eventually. If nothing else, you can't get around the fact that electrons can only move so fast.

Kind of off topic BUT since you brought it up you don't need liquid nitrogen to do that - we were able to use a really nice spectrum analyzer to downconvert (mixer output) the 2.4 GHz RF signal to baseband and then decoded it with a pretty modest A/D converter (11 Mb/s aint that fast). But even that was overkill we just wanted to be able to see the bits flipping :-)

BWJones (18351) | more than 10 years ago | (#7840358)

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?

Dual Xeon, Quad Opteron, Much Better Sense (1)

meehawl (73285) | more than 10 years ago | (#7840362)

Dualies or Quaddies would be a much better approach than this kind of nonsense. Why have a single (admittedly fast) CPU bottleneck?

Racing for higher MHz is a mug's game - that's why Intel, IBM, Sony, AMD, etc are moving to multi-core chips.

Re:Dual Xeon, Quad Opteron, Much Better Sense (1)

Indy1 (99447) | more than 10 years ago | (#7840453)

several problems with your approach.

First: a lot of programs either dont make use of smp or use it very poorly for any number of reasons

Second: the P4 (and its derivatives) make for a shoddy smp platform because they all share the same memory bus. Amd's dedicated memory bus per processor (with the opteron) gives far better smp performance, and benchmarks of the xeon vs opteron confirm this.

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.

Like trying to overclock a VW (5, Interesting)

xC0000005 (715810) | more than 10 years ago | (#7840406)

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.

Do they really need liquid nitrogen? (0)

Anonymous Coward | more than 10 years ago | (#7840417)

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?

Re:Do they really need liquid nitrogen? (2, Interesting)

Spam.B.gone (682244) | more than 10 years ago | (#7840584)

although -190 Celcius is indeed somewhat on the chilly side, I think N2 would be a sound choise: You need something with a boiling point somewhere below 0 celcius (so you have a nice temperature gradient to work with) and you don't want to worry about the environment too much when your liquid boils away. N2 fits, it is easily available and has the bonus benefit that it will nicely extinguish the small fires where the graphics card is trying to keep up with the CPU

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.

with that amount of ice crystals, I'm surprised it didn't short? I know it's distilled water but you figure minerals from the metallic elements on the silicon would contaiminate it and cause shorts?

I've done better than that! (5, Interesting)

Yes, I got 6.58Ghz out of my 1.2Ghz Intel Celeron. Image1 [geocities.com]

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? ;)

Eh, they are only there because I took them last year when I used my account to archive images and other documents. I'm now self hosting on a server in my room.

Yeah, could you move your site out of geocities before posting its links on friggin slashdot?

Overclocking is stupid--No, make that "insane" (3, Insightful)

shanen (462549) | more than 10 years ago | (#7840615)

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.

you're missing the point... (1)

TheCoop1984 (704458) | more than 10 years ago | (#7840636)

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.

Talk about journalistic integrity! (4, Insightful)

Hobophile (602318) | more than 10 years ago | (#7840687)

I saw this article over lunch today, and when I checked back just now I noticed they'd removed the page of benchmarks. One of the interesting results shown was that the Athlon 64 FX-51 managed to beat this overclocked behemoth in a couple tests.

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...

Benchmarks? (2, Insightful)

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.

Why Why Why??? (0)

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....
