Nevermind, I was thinking maybe because it is talking about liquid nitrogen and stuff that you were saying 'really cool' as some kind of joke... guess only I think of jokes that lame :smile:

Oh probably, those clever Intel monkeys :smile: The point is that 3GHz is no kind of limit.

perhaps some calming of downs is in order. to be honest, at this point, who really cares about them 3+Ghz computers.

OK, so you are saying they lied on that link I posted? Either you accept it as being representative, or you don't. I posted a link which showed that the CPU makes a big diifference, and you made out like it was somehow not valid and not relevant for no reason, proceeding to make up a limit that doesn't exist, before inserting a load of irrelevant information about itanium? It doesn't make sense.

Surely if that was clear in the first place then you wouldn't need to outline in such detail and "explictness" ? :razz:

First off I'm no ones master, except maybe to my dog.
I must appologize about my last post. As my idea's still stand I think that my remarks came off a little harshly, even as I just read it I can't believe I wrote some of that in the way I wrote it, if that makes sense. I appologize to you, Jeff. I must say I can almost guarentee that you know more then I do on the overall harware performance issues, but I was merely going off of what I know. And into further researching I did, today actually, It looks as if the Athlon 64 FX is a nice addition to the x86 gaming world :smile:
The main addition being the pipeline and extrodanarily large L2 cache, seriously, 1 meg . . . . Jesus. I think that is my personal next upgrade, so I wont have to upgrade for some time as it would work with 32 and 64 applications (unlike the Itanium). By the way, I don't really support Itanium, I just think its a pretty cool way to go about getting around the bottleneck. However, it's a son of a bitch to program. But nothing close to IBM360 . . . That's a suicide machine.
Anyway, again, I apologize for my ahem behaivor. :smile:

Would that even work? (The liquid Helium thing)... I thought semiconductors don't...er...semiconduct below a certain temperature. They just insulate. So unless you generate enough heat that it actually requires super-cooling, I think it won't work.

Normally a substances resistance decreases with decreasing temperature.

Heh, and turn your computer into a steaming pile of Bose-Einstein condensate or something and lose it up the walls. Good idea :wink:

hmm, yes this doesn't make sense then does it. If a semiconductor is an insulator at 0K (or has very high resistance at near 0K), how do computers work if cooled to these levels, given that their functionality is based on semiconductors conducting some of the time?

I asked some guy at a fair who was supplying liquid nitrogen coolers for multi-processor systems or something, and he said the temperatures generated are high enough to require this kind of cooling. Still, it's pretty surprising :/ Maybe someone else has more authentic info?

liquid nitro is cold as f**k. Hense when I said cool, jeff commented. I meant cool as in... well... cool. But Jeff decided to take it as cool = cold.

I doubt even liquid helium would be cold enough to stop conduction in most semi conductors, and it's certainly not cold enough for bose-einstein condensates. think mili kelvins there.
Semi conductors depend on a small energy gap between the valence and conduction bands typicalybetween 2 and 0.5 eV. Think of these as two seperate energy levels which electrons can occupy. Applying a small voltage to the material overcomes this gap and promotes electrons to the conduction band allowing electricity to flow. If the thermal energy was high enough to to promote the electrons without an applied voltage, then the material would be a conductor, not a semi conductor. You can calculate the thermal energy by the furmula E=kT where k is boltzmans constant and T is the temperature in kelvins. Hence you can find for yourself that at room temperature tha magnitude of thermal energy is only 0.026 eV, Hence thermal energy is NOT required for semiconduction.
Resistivity decreases with decreasing temperature due to the decreasing entropy of the system. Basicly this means, that if the atoms in the crystal are vibrateing less electrons are less likely to collide with them.
Conduction drops to zero at zero kelvin, yes. This is because all of the electrons are locked into the valence band. however I expect that by applying a voltage you are putting energy into the system and will heat it up just enough for cunduction. I'm not really sure what the actual behavior would be at 0 K, but that is a moot point as it is theoreticaly impossible to obtain absolute zero.
Edit Okay, I just read fraggard's link. I think that is all pretty reliable information, but it doesn't adress my question of how the applied potential comes into play. I stand by what I said.

I'm a chemistry major with a minor in physics WC. I've spent four years learning about all this stuff, although my solid-state physics knowledge is somewhat spotty.

I've been kind of pissed about the lack of a propper solid state calss at my school. the closest I've gotten is Inorganic Chemistry, and band theory was only really a very small section in that class. of course since it's just a natural extension of MO theory I have a pretty solid base for understanding the bits and pieces I do see. I am however quite disgusted that the physics department does not offer a calss in solid-state physics, particularly in this day and age!!
Anyway WC. I get my bachelors in just a few months, so don't worry if I know a bit more about some things :smile: .
I should certainly hope I would!

Don't think of it that way WC. I cannot begin to coprehend how much I have learned in my time at the University. It's like you go wandering through school for the first 20 years of your life before you reach true understanding of anything. even the first two years at University are very turbid. Everery thing seems disconnected and not very usefull, but at some point you reach a "moment". You suddenly see how everything fits into a larger picture, and be able to understand things you never imagined being able to wrap you mind around.
This happend for me in the middle of my Junior year here. it's an increidble feeling.

Ok, I bought the AMD Athlon 2500+ and a second stick of Crucial 256mb DDR 2700. Question, lol. When putting a new CPU, do I need to reformat? Cause I would think so, but nowhere does it mention it.

I highly doubt you need to reformat. However, I know very little about building computers.

Gave you a hefty answer in a pm, wc. Just kidding it's not that long.
Tracer, where are you graduating from?
My problem with most of the Physics, I don't have to take much of it, is with the way they introduce most of the subjects. It's kind of like, you sit there and learn it, in a terrible fasion (through work, not the -U kind though.) When they could have told you percicly what to use and when and why. In a very straight forward manner, I would understand, more so, of what I was actually doing. f**king PCC. lol Anyway.
I know the feeling you're describing. It started happening for me when I took my second Computer Architecture class. It was just kind of like "OH!" then connect whatever dots/light bulbs you'd like form there :smile:

Pacific University. Out in Forest Grove.
It sounds like you are suffering through a "workshop" physics class. A class where there is no lecture and you are suposed to muddle through the lab doing stupid experiments that teach you absolutly nothing.
Pacific uses the same format for gerneral physics. it is a horrible educational format, it makes it simply impossible to cover a reasonable ammount of material. the classes are just a painfull waste of time! Fortunatly the upper division physics classes are much better, and the Chemistry department is absolutly fantastic!

No, there's a lecture, a four hour one actually. Its just the way the book is set up. And the instructor, as cool and nice of a guy he is, just restates whats in the book. Do you see the infiite loop? (sorry, I had a Computer Science final today) On that note, I had an interesting conversation with a class-mate about how a CS student is essencially the human equivilent to the program stack lol.

I really know nothing of CS.
When I transfered from PCC I was undecided as to whether I wanted to major in Chemistry or CS. Well, they assigned my a chemistry professor as my advisor, so... I'm a chem major and have never had a single CS class. I think it was a good "decision" though. honestly I'm quite unimpressed by most of the other departments at this school.

You won't acheive anything by reinstalling windows just because you bought new memory and CPU. You don't gain much if it was a completely new PC apart from the hard drive.
That's assuming you have windows 2k/xp though. 9x and me are a lot less tolerant of things like that.
