I think this is a questionable technology to invest money in. Why spend however many hundreds of thousands of dollars this must have cost to alienate a very small but dedicated chunk of your userbase?

I doubt overclocking causes a substantial loss of profits through people doing it in lieu of an upgrade. The very few people I know that overclock processors regularly do it on old boxes that they use as playthings. They always have a very up-to-date computer that they aren't overclocking, they just take their old ones and see what they can do with them. These people wouldn't have gone out to buy a new processor for these old boxes if they couldn't overclock, they'd have just used them as-is. So by preventing them from overclocking, you're just making them more likely to buy a competitor's chip for their new boxes. I doubt sales would show any significant decrease from these hobbyists buying other chips but why turn away even one sale without financial benefit elsewhere?

Certainly manufacturers aren't regularly overclocking processors. It was Kryotech's main business when they started and they don't even sell an overclocked PC anymore.

The only reason I could possibly see for this would be to prevent accidental overclocking and I can't imagine that being a significant problem. Very few novices go out and roll their own PC's. Certainly not enough that there's a widespread problem with people damaging their hardware.

Don't get me wrong, I don't bother to overclock my machines so I don't mind them putting this into their chips. I just don't understand what would make this technology worth investing in.

Kryotech used to have a product that provided vapor phase cooling for Athlons. They sold barebones systems with case, motherboard, and refrigeration, and you provided the rest. They were achieving clock rates of about 20% higher than you could get with traditional cooling techniques at the time. Plus, they were officially sanctioned by AMD in the sense that using the Kryotech cooling system didn't invalidate your processor warranty.

Using Kyrotech cooling, you could get a system running at 1 GHz when the fastest official parts from Intel and AMD were topping out at 700-800 MHz.

Then AMD and Intel increased clock speed like crazy, nobody wanted to pay $2000 for a small bit of clock rate improvement, and Kryotech decided to stop selling consumer stuff.

This set up reminds me of kryotech. They broke the 1GHz barrier if i remember right. I wonder what they are working on nowdays...

this is the "hack" solution - one part cheaper components, one part coolness, many parts your time. If you just want something to work, listen to one of the other posters and buy something that's designed for this task.

1 - power - grab an old UPS. Most UPSs run off a 12V battery inside. It's trivial to mod this to run off your boat battery. In other words, old UPS == cheap AC inverter.

2 - case - buy a liquid cooled system (e.g. KryoTech) and spend some time with silicon sealant hermeti-cizing the case.

3 -

Vapochill did this over 2 years ago. Check out cpu bongs or Kryotech for real cpu cooling! This chills it down to -40 degrees C.

Or at least similar...

KryoTech Inc had/has a product that is basically a refridgerator for your PC. Been around for at least 2 years( the first 1gig athlon i saw.. months before the 900's were out was an overclocked 850 with their cooling system)

Looks like Kryo's a little more expensive, but a much more 'professional' looking system...

They use refridgeration units to cool the cpu.

When will we see intel and AMD pushing refrigeration units for their systems?

Ever hear of KryoTech? Their website is pretty much content-free at the moment, but they sell refrigeration systems for overclockers. They also sell prebuilt Athlon-based systems...they had Athlons running at 1.0 GHz months before AMD shipped true 1.0-GHz Athlons. Last time I heard, their equipment, combined with the latest processors, was supposed to enable speeds up to 1.5-1.6 GHz. If a 1.2-GHz Athlon is an even match for a 1.5-GHz P4 in most tasks, imagine how an Athlon @ 1.5 GHz would compare to a 1.5-GHz P4.

There are other companies out there in this business...KryoTech is the one that popped to mind first. I think Tom's Hardware did a review of a similar product from another company, and continues to use a system built around that product as its reference "absolute fastest you can get" system.

the country really needs to be run by the people who exist in the information age, not the agrigatian age.

We got som' a dem horseless carriages last year! Yee haw! I get up to 15 mph in my Edsel!

Heh. OK, now reality: I get over 2 Mbps on my cable modem here in the deep south. There are dozens of dot-com companies ( Kryotech ring a bell?) and ISPs in this solid-Bush Southern state. I work at one. Info-geeks and agrarians live here together in harmony, which is a Good Thing. No farmers, no food.

They say the country is split down the middle. Should we SECEDE ?

Does anyone know if Kryotech will attempt a 1.5GHz machine or something with these? I would assume you woule be looking at about $4000 for whatever they put together...

considering that I could already get a 1Ghz Athlon from Kryotech here kind of blunts the excitement for me. Admittedly, it was spendy, and they had to chill the thing to like -40C, but it was shipping. I wonder why AMD didn't flaunt this little gem more while they had the chance?

I recall back in December reading an article about AMD's initial announcement for that 1Ghz chip and the article pointed to a link here for a company that makes cases with a cooling compressor for the chip. &nbsp And according to the company, this case is for the "home user"!

Should be interesting to see Intel's 3.5 - 4.5Ghz chips soon and the liquid nitrogen coolant I seem to keep hearing about (no lie - I have heard that)... &nbsp ;-)

Is there any difference between the new 1Ghz chip about to be released and the 800's overclocked to 1Ghz that are already avaliable at places like Kryotech? Are the new retail chips actually designed better (ie smaller die, better cooling, new layout...), or are they essentially just overclocked versions of earlier chips?

Kryotech is selling the Super G, a 1000mhz Athlon running at a temperature of -40C.

However, your problem is not the chip speed, but the surrounding bus speed and RAM speed. The chip runs at 1000mhz, but the Front Side Bus is only 200mhz and the RAM runs at 100mhz. YUCK! Talk about your kinks in the hose!

The things you'll want to address before you improve your cpu speed are:
1) RAM speed. You'll theoretically wanna blast open that blockage in the pipeline with 800mhz RDRAM, although it has been shown that this does not deliver anywhere near the astronomical improvement that it is meant to deliver.
2) Cache speed. It runs at half the speed of the cpu - or, almost half. This needs to be rectified ASAP.
3) AGP support. This is very important in games. I predict AGP4x will really unleash the speed demon in every computer.

Is it any wonder that with all these bandwidth limitations, the Super Bypass only yields a 2-5% increase in performance over a non Super Bypass board?

Kryotech's 1GHz Athlon system, "SuperG", is already shipping. Tom's hardware reviewed it more than a month ago, and it was very stable, and very, very fast. To quote Tom's:

Price and size aside, this unit will go down in the record books as the first consumer PC to hit the streets at the magical 1 GHz. Although 1 GHz doesn't really do anything special, it has been a number that most of us have thought to be a leap beyond. I can only imagine what we'll do when get our hands on a .18 Athlon to slap into the SuperG. If you've got the cash floating around and you want the best, Kryotech is undoubtedly your source one for the fastest PC in the world.

1Ghz Althon (granted its overclocked. but safely and guarunteed for 1 year).

been out for a month. Super G from Kryotech.

TomsHardwareGuide has reported on the easy of overclocking Althons and the problems getting a PIII to just go 50Mhz faster.

-Z

I'm the kind of user who doesn't give a crap about who makes the chip, or how much it costs, just as long as it's the fastest mainstream consumer chip available. And as the basis of that, I'm still going with the Athlon for two reasons. It beat the new PIII in just about every test. Second, I haven't seen any super cooled PIII chips that are like what Kryotech has done. Can you say 1 GHz Athlons by December? Mmmm

We are pleased to report, however, that our recently acquired redundant parallel storage system has gone a long way to help buffer this crisis.

We do have a special request for Slashdot readers: we would greatly appreciate it if you would restrict your postings to original questions, rather than material cut&pasted from our home page or from other sources. Repetitive, unoriginal input text tends to cause numerical instability in our NLP algorithms (performance of the FPUs in our Kryotech Athlon 900s seems to be particularly sensitive to divides by near-zero numbers)

Thank you!

Yes, Celerons are easy to overclock. However, later model PII's and PIII's are impossible to overclock without modification as Intel locked their clock speeds. I should imagine that the next generations of Intel chips will be exactly the same.

How much heat can you seriously expect to suck away from the processor core? Well, as an example Kryotech manage to suck away enough heat to allow them to run a regular Athlon processor at 900MHz.

Actually, there is a VERY VERY nice HOWTO on how to overclock your Athlon to 1050 Mhz here . I do find it silly that you can clock it up to 750 with no additional cooling and that extra 50 Mhz requires a portable super-freezer. My guess is using the cooler (which is available seperate on kryotech's site.. The Kryotech Renegade) you could slap an Athlon 1050 in the box and have no stability problems whatsoever.

I was just looking around, (KryoTech's product page) and while I was there, they updated their products page to include a 1Ghz AMD Athlon (K7) machine. It has links to a press release that they gave at a shareholder's meeting, and a Q&A session. Pretty cool stuff. It won't come out until the end of the year, but it will probably beat Intel to market. db48x@yahoo.com

Another note (even though I haven't read the other replies...) 900Mhz cordless phones just have a radio transmitter that is tuned to 900Mhz. Its compleatly analog for all I know. It really has very little to do with creating digital things at the same frequency. (There was an article on the AirPort for Macs, at 2.4 Ghz... same deal. It doesn't actually use a 2400Mhz chip, just a radio transmitter tuned to that freq.)

Not only has Kryotech been making -40 degree systems available for some time, they now sell empty cases with refrigeration units. You can buy one for 350-400 bucks US.

Kryotech Renegade

here's the link for 1 GHz Athlons: Kryotech Super G

Electromigration is supposedly one of the damaging factors of running a cpu overclocked. The electromigration will shorten the chip's lifespan by making weak spots in the "wires". Cooling of the chip helps make the aluminium less resistive. Does this also lower the amount of electromigration? I believe it does. Perhaps all chips in the future will have to be built like Kryotech's computers.

Kryotech is gonna sell a 1 Ghz AMD K7 by like this fall....

It's only those extreme cases of people with Kryotech systems or people who submerge their mobos in mineral oil that you ever hear about.

Q13: Will the Super-G be used as a workstation, or as a small server, or as a very high performance personal computer?

A13: Yes(!) The Super-G is a very high-performance uniprocessor computer system. KryoTech expects it will be used in many computing environments where a very fast uniprocessor system is needed.

Looks like not even Kryotech can get a hold of a dual K7 (and you know that if they could make a dual GHz machine, they would -- wouldn't you?). At least if they had a demo of a cooled SMP K7, we'd know if such a thing even exists. I personally can't wait to get a K7, and I'll probably get one the day they come out. But if AMD will have dual CPU setups coming out later, I'll have to wait. Does anyone have any info about a the dual K7 rumors? I haven't been able to find out anything.

Also, you might want to get Kryotech into the next century and tell them to ship with Linux pre-installed. I already mailed them about it and you can to. Kathy Hemby is the person you want to talk to. Maybe if we /. them, they'll wake up.

For some _real_ cooling, check out www.kryotech.com.
That stuff is awesome. Can we say "500 MHz K6?" Heh, heh.

You're possibly thinking of Kryotech. They retail overclocked Alpha and AMD-powered boxes, with their patented refrigeration system built into the case.

The trouble with frosty heatsinks is: I go outta town for the weekend, the power to my apartment dies. My UPS is only good for about 15 minutes, so in a half an hour, this thing stops cooling my CPU. Then the frost melts. This is a bad thing(tm). A much better solution, having not actually gottten to this slooooooww site, would be the Kryotech system. Check out Kryotech. They cool the CPU down to -40C with no frost. They actually have little heaters in the heatsink to prevent that, but still cools the chip!
