My argument has nothing to do with whether or not a processor can be overclocked. Of course it can. My argument is that you cannot have dye temperatures at -40C. Sheesh. If I write too much, you sure do read to much.

This has been done before. It was posted on Makezine or slahsdot awhile back. Though it is possible to use Dry Ice for cooling, it is not recommended. Another example of using other things for cooling that were not meant for it is this link:

Here are some guys that did something similar.

How did you start overclocking?

I started because I was using a crappy nVidia 5200 to play a resource hungry game (HALO for the PC). I couldn't get it to work even with the graphics down, so I found out about overclocking and started me experiance by busting my card.

Echo, reading your other posts, I concede that you know more about overclocking than I do when it comes down to application. I'm just giving a purely physical interpretation under a certain set of conditions. Anyways, what that means is that the junctions at the semiconductor level in the transistors cannot handle 2.8GHz of oscillation because they were not designed for it. That is, the physical structure of the material was not designed for it.

kg_lildude1 · Nov 08, 2005, 11:07 PM // 23:07

have you ever overclocked it so much that the chip just smelts to the side of the casing?

yea uh... don't do it >_>

My parents always said to get the best stuff so you won't have to upgrade it for another year or two....
Too bad all of my computer stuff is expensive.

That's cool! The oil part... hehe that's great. As far as the method with the ice, he didn't directly use it to contact the packaging of the dye.. as I thought the OP had done.

I'll just let this one rest, as I'm tired and don't care to drag it out.

Sir Skullcrasher · Nov 09, 2005, 12:20 AM // 00:20

Are you pumping dry ice directly into the system? And how it is possible to overclock a Pentium 3 into a 2.8GHz?

And someone (zehly and others) answer this..is it even possible to use dry ice into your computer without freezing all the parts in it?

The dry ice (apparantly) does not have direct contact with the computer; rather, the gaseous form (that which has been sublimated) is used to absorb heat. PCB will become brittle at -100C. I'm not sure exactly of the effects of putting dry ice directly into a running system. I will try it tomorrow with a ghetto system in the lab. I've been meaning to get rid of that stupid P4.

is rarely used in conjunction with electrical components. Liquid nitrogen works better.

The presence of carbon dioxide gas is normally around .05% of the atmosphere that we breathe in; we breathe out around 4-5%. Inhaling more than 5% of carbon dioxide gas is hazardous. Excess carbon-dioxide changes the pH of our blood and causes hemoglobin to function adversely.

Silicon-based microprocessors:

T-Junctions as well as other parts inside transistors react to change in temperature.
Change in temperature will affect the resistance across a circuit.
If a processor gets too cold, it conducts more electricity (resistance falls), and will eventually lead to a short/spike in electrical activity.
If a processor gets too hot, it conducts less electricity (resistance rises), and will eventually melt the dye, causing a short, and then fire.
Room temperature is relatively ideal for semiconductors in home-computing.
The Pentium III processor CANNOT EVER reach a temperature under -40C without destroying it. This is either powered on OR off.
You would not have a deficiency in voltage; you would have had too much!
The P3 CPU does not support 2.8GHz of oscillation. Period

So, all in all, what you did cannot be done. Oh, and this was proven too; I had my students try it in the lab using PROPER EQUIPMENT! The die shorted, sparked, and fizzled.

I'm not posting this as a flame, though, just as a minor correction.

Ok let me point out a few things.

1. It is not in a CLOSED container. It is in an aluminum container which is covered with neoprene.

2. The electric current can be discharged with material such as to say, RUBBER? Oh wait, that is what covers the HSF on the CPU.

3. I did say there was a slight burn mark. Note it was at -52C for a very short period of time.

4. I also stated that voltage was a problem as well.

That last part was definately uncalled for. She did say that she wasn't trying to insult you.

Plus I hope this thread is closed. Flame wars are pointless.

unienaule · Nov 09, 2005, 05:18 AM // 05:18

Um, some people dont like it when other people randomly accuse them of lying, and pretend to know everything about a topic. As Zehly should know, sometimes electronics does random stuff that you would never expect to happen. Ehxibit B: I have a battery-operated device that has batteries which expired under the first Bush administration. It still works, and I played with it almost every day as a kid. Logical? No. But I'm staring at it.

Lord Weevil · Nov 09, 2005, 06:15 AM // 06:15

I am very, very familiar with overclocking of processors.

Yes, dry ice can be used, and is used somewhat frequently in the hardcore overclocking enthusiast community.

Processors CAN and DO operate at -50c temperatures (although some dies are more susceptible than others to the effects of subzero temperatures).

All that said, I cannot possibly believe a Pentium III hitting 2.8ghz. Not due to the limits of silicon necessarily, but the fact that there is no motherboard compatible with a P3 that would be capable of hitting such a high front side bus.

Now, if you were talking about a Pentium M, which is based off the P3 architecture, that becomes more likely and, indeed, quite believable.

However, given the stated conditions, I'm more inclined to believe you're lying.

By the way, if anyone would like to read more about extreme cooling options, I would recommend the www.xtremesystems.org forums. You will get to read about all sorts of fun cooling suggestions.

Also, I don't post every day, and I don't make claims.

Graduate level....physicist?

That does not mean Physicist does it?

Techie · Nov 09, 2005, 12:01 PM // 12:01

No it is not stated as a flame and not meant to start a flame war, I do not appreciate [insert name here] thinking I am lying because of what he/she knows about OC'ing. And if I have to say it 1 more time someone is going to get thrown off of a cliff:

IT WAS VERY UNSTABLE

I didn't say I had it running games and benchs, just that I got it to load Windows.

zehly · Nov 09, 2005, 01:19 PM // 13:19

I regret even posting in this thread. Such a shame what's happening to this site

Omega_2005 · Nov 09, 2005, 02:38 PM // 14:38

I'd only accept it up to 100% of it's processing power, so it was very close to blowing up at 5.6x the original processor!? Very risky but I salute your experiment

DUDE UR MY HERO .... i just posted sumthing like that days ago and no on e velibed ne ... LOL .... r u a computer sicnce teacher .. man ... i jsut tougth that that sounds IMPOSIBLE ... my intel burned a year agfo when i set it to a 0.2 overdrive ..... and sides the bios wont let u overdrive that much ...
