More on Athlon Overclocking
The Tech Report is running an article concerning Athlon overclocking. With the 1Ghz+ chips coming down the line apparently soon, will things need to change? Or will it be just a documentation change? The other change is the issue of moving to on-die L2 cache - how will that affect things?
does anyone know the relation between a p3 mhz and a athlon mhz? (or, for that matter, a g4 mhz)?
Someone should send that link to Al Gore. HAHAHAHA!!!
Thanks for asking!
Can anyone confirm this? Either this dude is too intelligent to be on Slashdot or he's blowing smoke up our asses.
You're right. Only off by 20%. Not bad at all.
IMHO he's exaggerating the risk. I haven't seen anything like what he describes. The clock-monitor throwback on the Athlon is (a) very robust, and (b) far enough from the L2 that you're usually safe. Sure, it can happen, but only in really extreme cases. Of course I don't work for AMD and I'm not "in the loop", so don't take my words for gospel. Still, I am quite familiar with the issues of this design.

Just wanted to clarify that, thanks.
I have a few applications which could use the CPU (aside from running gcc), but they're not exactly typical. I have some perl programs which process very large data sets (mostly extracting certain relevant information from downloaded english text), which would be at the top of my list. I know I could get a 10x or more speedup rewriting my code in C, but I have a lot of other projects which I want to work on more than I want previous projects to run faster, and development times in perl are very short. I also use bzip2 to compress archived data, and bzip2 is a real hog. I understand it's also a cachebuster, which means I'd benefit more from an improved main memory system than from CPU power. I'm not working on anything else right now that takes a lot of CPU (outside of the office), but someday I'd like to develop software for SMT platforms, and until someone builds an SMT I can afford I'd have to test/profile my code under a simulator. Not having to wait forever for the simulator would be nice.

On a similar vein, one web site (MacOSrumors?) indicated that there might be some problems between Motorola and IBM with regard to the G4. IIRC, IBM may have the ability to produce the G4's with a faster clock speed than what Motorola can produce. This would not necessarily be surprising as IBM has some impressive chip production capabilities.
BTW, has anybody documented problems with these faster clock speeds and 900 MHz cordless phones? Just wondering.
And I'm still saving up for an Athlon 500mhz box..
You are at least as stupid as they are. Overclocking a cpu is stupid. Overclocking memory, OTOH, is the most brain-dead, idiotic, deadass dumbshit thing you can possibly do. You are essentially saying "I WANT random crashes." I hope you all burn up your crappy hardware.
Whats with these stories people? They're ALL crap! How about posting stuff that we really care about for a change???
... or the PS2 story?
/. fan
How about Tripwire story?
Pissed off
Moderate this up if you agree.
What is worth the risk of an unstable CPU? Or worse, a fried $700 CPU? ANd how does one "know: that your CPU is really stable at the faster rate or just teetering on the edge of insability? How can you live like this? You people must have some sort of death wish!
& how about chipset/mb's that can support more than 768mb of memory. wtf?! So much for trying for the high end. I've been asked to put together some systems & athlons are out of the running because of it. Large data sets(1-3.5gb) on a closed sourced app that runs under solaris or nt. alpha's out from nt being dropped. They wan't to do it with inexpensive pc's instead of ultra's(what it's running on now.) Going with gx based mb's that handle 2gb. Hell, can even plop celerons into the boards. 'low end' celeron more viable in high end market than athlon because amd screwed up with strategy on chipsets.
Hey buddy thanks for making my day. That was fucking hilarious. I can't imagine anyone believing you but it's a great laugh. Cheers!
(sigh) Yes indeed. Has it occurred to anyone that Seymour Cray has already been down this road? You know, the guy who holds more patents for cooling technologies than anything else? Unlike these pieces of junk, though, his machines were actually fast. I will never understand why people feel it's necessary to spend double the money on cooling for a 5% performance increase when spending an extra 20-40% and buying higher quality components and faster i/o subsystems can double or triple performance. I mean, a three-year-old workstation can be had on the used market for less than $4k depending on configuration of course and will usually give better performance than a peecee with the latest processor overclocked to the greatest degree possible with liquid helium and a cooling tower. Of course, the crux of the matter is that those systems won't run GameOS which all these wankers want so they can play their 31337 g4m3zzz!!!!@@!!$$!!!#!!!. Idiots.
I think CPUs ought to have some sort of internal fusable links that get blown at successive clock speeds, not to disable overclocking, but so that the buyer can determine the fastest rate at which the CPU was ever run at, thereby detecting overclocking attempts which may have subtly damaged the CPU.
Get a faster CPU, or a dual/quad/etc. motherboard and multiple CPUs. Can't afford that? Then tough noogies. Don't overclock shit and then sell it as a faster model. You people are worse than Hitler's toe-jam.
I want you to notice something: your post was moderated down before that JonKatz-Nazi thing, which was posted an hour before. Don't you get it? Just go away. If you're looking for a new home, try here.
Flame me and I'll release a 12oz can of R-12 (I've got cases of the stuff bought in 1985) into the air, in your honour.
What he meant was that the RF radiated emissions from the CPU is in millwatts. Radiated power is not the same as consumed power due to current drawn. By the way, I am not sure if a CPU can radiate in the tens of millwatts range. Probably if the PCB traces of the motherboard will act like a high gain antenna...

I'm a huge UCB fan. And the new season is really kicking ass so far. I watched my tape of the new "Spitty Splurpy" episode tonight. That episode was aired tonight, too, actually. They were *supposed* to air the "food" episode, or at least that's what the online schedule said, but they fucked up. I was pissed because I missed it last Monday and the Monday before. (I don't watch much TV besides UCB so it's hard to remember :-)
Be sure to tune in this Monday. "Ladies, I give you... the VIRBRATING BOOT!"
gameOS ? fuck off you jackass zealot. some people like to play games. dont blame us for the os they are written for.
cock.
Name 1 reason a non-technical user would have for a cpu running at 1Ghz?
Quake. Unreal Tournament. Oops, thats two.
I can't beleive they yanked it. Slashdot Censorship !!! This is truly lame. Slashdot can't even post the important stories that do come across their inbox. I can only imagine Taco thinking "too contreversial, I only do linux and star wars". Truly fucking lame of that young Republican fogey.
Same as 800 OC'd to 1GHz, except with better manufacturing which means they can run reliably air-cooled, unlike Kryotechs which has a huge refridgeration unit. This is not to say you can't find an 800 that can run reliably at 1Ghz air-cooled, but the 1Ghz from AMD will pass AMDs tougher tests at 1Ghz and won't require cooling options like peltier coolers etc.
Well, GameOS is the generic designator for an os that isn't good for anything else. It could be Lose98 but there's no specific requirement.
And let me tell you, there is a lot of purchasing power from the Gamers...
Yes indeed. Hopefully we will start to see some economic downturns soon, and then the kiddies won't get so much money from their parents. That ought to take the wind out of the gamez market and restore some sense of sanity to peecee design. I can't really blame the peecee vendors for making shitty products; they're making a profit. But I can blame the idiot consumers for buying them.
As well with greater than 768MB of memory.
Of course Quake III is a distorted benchmark for real world computing!
However, for peckerwood rich kids that spend lots of money on fancy video cards and top end CPUs it its important because it reflects the primary application base.
Moral of the story -- don't put too much faith into the SoNSo's Hardware sites - They are far too focused on gaming and Windows 98 to be of any real use for the typical Unix/NT workstation user.
I like games too. But not enough to run GameOS on my systems. I'm not "blaming" anybody for anything, because I don't care what OS you losers use. Far's I'm concerned you guys deserve winblows. GameOS is the proper name for any system that's not good enough for anything but games. That tag applies to more than one, FWIW, some of them intentionally designed that way.
What is more likely is that he has some inside info and the only way to get it out to the public is via this forum.
When the Athlon first came out they were .25 cores, now the're .18 mn
The original story that got cut
AMD, naturally, will never tell you of the risks you run in using their products, but you have a right to know.
The L2 cache design is really still experimental. The old L1 architecture is proven, but it's just about tapped out performance-wise, so AMD is moving on. Sadly, they're releasing designs that are not yet "production-ready" in a few crucial respects. Under certain circumstances (multiplying > 1k x > 1k matrices of doubles, for example) the L2 design will "underclock", or in engineering idiom "sprag". "Spragging" means, in layman's terms, that a lot goes in and nothing comes out. This happens when fast swapping cuts in during cache defragmentation with a mod zero byte block size in the under-storage. The result can be as small as a die melt ("burnhole"), which will require you to replace the unit (yes, that's "small", relatively speaking) to an extremely fast and sudden heat buildup: The L2 cache warms up only slightly, but it happens to be very near the clock-monitor throwback module. Yes, you heard me. You don't want your clock-monitor throwback to be soaking up any joules from a sprag, believe me. If the "glow-up" is fast, it'll throw a burnhole in the substrate and that's all she wrote. An expensive hassle, but not a major tragedy. Unfortunately, slow glow-ups do happen from time to time (larger byte blocks in the under-storage can cause this) and in that case the substrate won't burn-through before the clock-monitor throwback gets hosed. When that happens, look out, you've got the thing spinning out of control. Have you seen those cryonic supercooling rigs for seriously overclocked chips? Do you have any idea how much heat they're soaking up with all that liquid nitrogen and so forth? A hell of a lot of heat. Your computer under your desk doesn't have any liquid nitrogen. Fry your clock-monitor throwback and you'll wish it did. Here at AMD (that's why I'm an AC, duh) we do keep liquid nitrogen in the lab when we work on this bug. That's how serious it is. A couple of engineers have been very seriously burned, one so badly that he's on permanent disability.
Be safe, be careful, is all I'm saying. It's a rare, freak glitch, but it can happen, it has happened repeatedly in testing. And it can happen to you.
It's been covered up, obviously, with the connivance of the liberal media, but at least three moderate-to-severe head-explodings have been recorded in ordinary household usage of Athlons. Don't let this thing near your kids. It'll pop 'em like popcorn.
I actually do feel stupid; that story was never meant for the Slashdot front page. I meant to leave it as a joke to anyone going through the stories list tonight as a 'how long has it been since you've seen this' piece. :) Sorry for the mix-up. --Emmett

Additionally increasing the clock gives the charge carriers less time to move, if it cant make a difference to the far side of the active region of the semiconductor, it isnt working. Increasing the voltage increases the electron drift velocity. Increase it too much and theres a chance of electrolysing your chip ;)
You also dont want to reduce the temperature too far or kT will drop to below the bandgap, turning the semiconductor into an insulator.
The best way of increasing speed is to reduce the size of the active layer, but soon we'll start getting quantum effects, which in current designs, are unwanted.

Wow, such an enlightening site. This stuff really needs to be reigned in quickly. People are dieing because if our lack of action.
Their studies were very nice as well. The remind me of the UCB bit where they got signatures to stop Women's Suffrage.
The food one was very nice. You mustn't let these slip ups happen again. Get yourself a Tivo. That takes care of everything.
Boy lemme tell ya, if anyone is gonna spend the $1200 (or whatever) for a 1000 Mhz chip, and doesn't overclock it, they are downright fools. I mean, how can you look at yourself in your monitor's reflection every day with a measly 1000 Mhz machine? Sure you compile kernels in 5 seconds, but look at the guy down the road. He's running his at 1700 Mhz right now, pulling in about 738 fps in . Yeah, that's right, you non-overclockin weirdo, you.
Ladies and gentlemen. Do not let this scenario happen to you. The next time you remortgage your home to buy a CPU, remember, overclock that puppy to heck. Thank you.
This has been a paid advertisement from the Go Ahead and Fry that CPU Foundation.
Anyone know of a motherboard anywhere that supports two athlons, that was sposed to be a big technology benifit when they were introduces over pentium 3.
Of course they are. They're engineers. And the instant the marketdroids realize they can drop costs and increase profits by forgoing the shielding they will do so. And if past experience is any guide, people will buy it even though it interferes with their tv, radio, and other computer equipment, and cooks their brains. These are peecee buyers we're talking about, not intelligent human beings. If they'll buy aol, they'll buy anything. Now we just need to find a way to sell them a "computer" that is actually just a metal case connected to the appropriate line voltage. Pfffzzzzt, no more peecee luser.
Yes, but what about when your L2 cache goes into mod zero byte block mode and slags the hell out of your cpu? That could easily lead to multi-megawatt emissions of head-exposion-causing microwave radiation madness! Write to your congressman/MP now, before it's too late! Think of the children!!!
rated speed to avoid single-bit errors and the like
SBEs, eh? Well, that implies that you invested in ECC memory. Investing in higher quality components is highly unusual for an overclocker. I can assure you that most of them observe SBEs as a BSOD in their GameOS, because they spent all their cash on a higher-clocked processor and then bought Joe's Factory Thirds "PC92-1/2" Memory from the guy on the corner wearing a trench coat.
Fortunately for the engineers, there are FCC requirements for emissions and inteference, so they can tell the markedroids to shove it.

"L'IT c'est moi!"
Microwaves are optimized to produce microwave radiation and use a wave guide to concentrate the energy in an enclosed space. Faraday cages are very good at blocking high frequency radiation so not much leaves the box.
In CPU design, radiated power is minimized because it is required to get an FCC license of the device and because radiated power can cause interference within the box itself which is obviously a bad thing.

"L'IT c'est moi!"
But, according to this Anandtech article yhey will hopefully be available by the end of 2000.
Hell with that! *REAL* overclocking was desoldering one's 6809 CPU and replacing it with the 6309(?)!

Don't like it? Respond with words, not karma.
I'm sorry this has turned out to be a rant all, please forgive me. Theres nothing I get more passionate about then technology and the Average Joe who's going out to buy that top o the line CPU to run his wordpad. If it wasnt for Joe Average spending tons of cash buying the top of line CPUs, do you think these companies would have the money to develop better chips as quickly? Or the desire to? Just because you only drive 3 miles a day to work, and to church on sundays don't mean you shouldn't drive a BMW/Cadillac/(insert expensive car here) and look good doing it. I hate when elitist geeks spout superiority over your typical user. Get over yourself.
This message brought to you by the Council of People Who Are Sick of Seeing More People.
One difference between factory marked and overclocked chips is that the factory marked chips have been tested at their rated frequency by the manufacturer. This is an important difference for non-recreational users. A dealer or end user can not properly test an overclocked CPU. The manufacturer uses a very expensive chip test system with proprietary test vectors.
Mea navis aericumbens anguillis abundat
It does make sense for anyone, with the money, to buy at the top of the bell curve (750MHz PIII or Athlon) rather than several steps behind it (Celeron 333A, K-6 3D). In most cases the difference between the high end and low end is $1500 at most... In reality, for a machine that you expect to be functional for several years, that's not that much money.
So long as deevelopers know that faster CPU's are on the way, they'll continue to write programs that sap just about every available resource from the machine... Intel's salivating at the prospect that one day Win NT/2000 will be dumbed down enough to run the worlds desktops.
Windows is one example of code bloat... But there's also X, and especially the newer WM's, like Gnome and KDE... And as opensource developers try to match Microsofts applications in features, there's bound be more and more bloat on the way.
Remember, 10 years ago, what was the norm? 16 Mhz? maybe 25? or even 40 MHz AMD 386's? But regardless, for most apps, those were probably good enough, too. The person that says that 750 MHz is good enough for everyone can almost be compared to Bill Gate's (though i'm not 100% possitive it's his quote) "640K ought to be enough for anyone"
Hold up a bit there!
The real heyday of overclocking was the PC-AT, with the socketed crystal! No fancy-pants jumpers, DIP switches, BIOS settings, or anything!

I'm not so concerned about 1GHz CPUs anymore. I want to see supporting subsystems match the processor's performance, specifically video and memory. It would be very interesting to have a 500MHz memory subsystem and a 1GHz 256bit 3D video subsystem. By way of example, I have recently been able to extend the gaming life of a number of older P/PII systems by giving them Voodoo3 3000 PCI cards. How much more performance could we all get from a bleeding-edge CPU if everything else is running just as fast?
Am I the only one thinking we'll be seeing the BiAthlon and TriAthlon just like the P2 and P3 came along?
:-(
Possible, but personally I'm hoping they'll call the dual athlon a biathlon etc. Not much chance of a pentathlon that way though
According to this Electronics Weekly article, on non-graphics intensive applications like the LINPACK benchmark the Athlon 800 Mhz CPU performs twice as fast as a Pentium III 800Mhz. It goes on to mention that the Quake 3D test which is so widely used is in fact faulty. Underclocking both CPUs to 400Mhz (i.e. halving the speed) and using an nVidia GeForce caused the frame rate to drop by only 2 % at the highest resolution! There is some serious bottlenecks on the video card. Who needs a 1Ghz CPU then?!
I can't believe this. Slashdot is now repealing stories???? What happened to the Dihydrogen monoxide story! That stuff is dangerous, see The Dihydrogen Monoxide Website for the full story!
Yes, I know this is offtopic for this story, but the fact that Slashdot repealed such an important story is unbelievable!
Did anyone save the link to the story on Slashdot? If so, post a reply to this!
Hey, thanks dude.
Honestly how many of us are going to use a 1ghz processor for something other than RC5, Seti, and Quake 4? Thanks, but no thanks, i'll stick with my 266 and keep stacking on the ram and storage. I have yet to see a useful program that requires mor than a 266. Sure, maybe some new media device will come along soon, and it will be a must have, but right now I'm running netscape, mozilla, xchat, gaim, x, and enlightenment, and my processor is 97% idle.

Then Kryotech can overclock and cool the NEW cpu! that's what's great about them, upgradability!
I have an athlon 750 with the asus k7m motherboard. Overclocking is as easy as going to bios and selecting what I want the FSB set at. I havn't messed with the multiplier (its a jumper) but by changing the bus I can get it pretty high, not sure exactly how high, but well over 800mhz. I was running it over clocked for a while, but got paranoid that it was causing problems. Maybe, may have been flukes.

When I said the cache was helping the P3 in comparitive benchmarks, I wasn't referring strictly to fp/gaming, but to benchmarks as a whole. On-die cache could make the Athlon bench faster all around, not just on some benchmarks.

Full-speed cache is the only thing letting aluminummines approach or outperform Athlons, just look at the graphs and you'll see that the P3s get closer and closer as the speed increases, and the Athlon's cache gets slower and slower by comparison. With full-speed cache, AMD will be in a very good position as far as benchmarks go. If you think the Athlon is a good performer now, just wait. :)
Am I the only one thinking we'll be seeing the BiAthlon and TriAthlon just like the P2 and P3 came along?
-----------------------

Well, that's one view.
;-)
The other view is that more and more mainboards are using DIP switches instead of jumpers, making it easier. And of course ABIT brought BIOS-level clock setting changes, which (IMHO better)companies like ASUS now include.
I haven't had any athlon-overclocking experience, but I understand it is more difficult than changing a BIOS setting.
Power consumption of an Athlon and/or a PIII are on the order of 20-45 watts. No where near a kilowatt, but still considerably greater than milliwatts.
When information is power, privacy is freedom.
Instead, you'll need a device that sits between the chip and mobo
Has it struck anyone else that this needn't be a separate device, but could be a part of the mobo. Overclocker friendly mobo makers (hello ABIT, are you listening?) could include the circuitry in the board, and configure it from the bios... now that's easy overclocking!

Comment submitted. There will be a delay before you understand what you posted.
we have to assume that they are actually designed better.
As far as I know, these are the same K75 core, 0.18 micron die chips.
The difference is probably just in yield. When Kryotech released 1Ghz, there were to few chips capable of running at 1Ghz air-cooled. Now, the proccess has run longer, it is (probably) tuned somewhat, and AMD has had time to save the best chips for a while. Remember, neither Kryotech nor AMD need to sell huge quantities of the top chips... the prices are huge!

Ahem. CPUs are not cheap. :P My Athlon 750 cost me $550 when I bought it (would have paid $650 if I didn't have to wait for the next paycheck). Okay, I have to back up a little bit. High-performance CPUs are not cheap. The Athlon 650 actually costs less than the 600.
As I understand it, AMD stopped making 600's and 650's sometime late last year, and to keep up with the demand that was still in place for the lower-clocked Athlons, they actually underclocked 700's and 750's to keep up.
My very same CPU now costs about half as much as I paid for it with not even a month passed.
And to the guy that said Athlons are hard difficult to overclock? That is shenanegans. AMD made a little connector on the top of their PCB that lets you slip on a little (tiny) overclocking device and go to town. You can use it with the cartrige installed, but what the hey. You need to take off the cartridge anyway if you want to use a "decent" heat sink. (I bought an Arctic Cirlce cooler)
Uh, dont you think that companies would be smart enough to have shielding around the processor itself, rather than relying on the case? I think people think retards work in the R&D section of companies, they ARE aware of severe problems like THIS.
SpamMan
No, actually, Intel has said for quite a while now that they would be releasing one gigahertz at the end of the first quarter. Although, as you said, this will only be in small quantities (which is in fact true). Don't expect these in stores until the end of the year.
My whole feeling on the processor war, is that Intel/AMD could release the chips now, they just don't, to make their businesses thrive. Like, this way, you have to keep upgrading... and therefore they get more money. Well, I don't know about my reasoning, but I'm pretty sure that my hypothesis is true.
are they essentially just overclocked versions of earlier chips?Well, since they will not be using any Kryo-cooling technique on the chips, we have to assume that they are actually designed better. Otherwise why would Kryotech bother working on their cooling technology to get it to work if air-cooling did the same. Now, they might be slightly more overclocked than currently (perhaps the 1Ghz is a 900 overclocked or something) but for that, we'll have to wait until the chips come out for some good analysis.

** Evil Canadians are taking over the world. Learn about the conspiracy
Complete bullshit. I don't think I could have loaded one up any fuller than this. Man, It must have taken a while to come up with all that crap. What did you eat? Let's just say that, if you really work for AMD, I hope you keep the toilets clean, cause only a janitorial worker could pull up all that B.S.
OK, to set the record straight, the L2 cache is a proven mechanism for increasing the average access time for data in a computer system. On die L2 caches can be as simple as you like. The performance gain comes in the high bandwidth availability and the distance from the processor core. The only real problem with on die L2 caches is that they increase the size of the die, and the cost of the chip.
If I were to believe that AMD had such problems, then it would NOT be in the design of the L2 cache, but rather the implementation. And I don't think you could implement such a simple device in such a poor manner. I could build an L2 cache with tinker toys that worked better than something that had these kinds of problems (problems which, by the way, CANNOT physically exist in the way they are described here).
Ok, so like let me overclock my 1GHz to what? 1.1?that's not really neat... the percentage gained in performance by overclocking goes down as the speed increases, because the relationships between die size, speed, and heat are exponential not linear... The faster things get, the harder it will be to overclock, at least without cooling... I see a nice future for kryotech...

I am not a lawyer.
Yeah. There are CPU diagnostic programs for PCs, such as AMIDiag, but few users have them.
Well, being a former overclocker myself, the hey-day(-5 points for spelling) seems to be over to me. No longer is overclocking simply a dip switch or jumper change. With these new cartridge-afied CPUs, you hafta break into the things, and maybe even de-solder and then re-solder those miniscule eyeball straining resistors. With chips running as fast as they are nowdays, I opine that a modern-day overclocker is significantly more bleeding-edge than those of yesteryear, like me. I do admit that I miss it...

Water can boil at any RF frequency. When you radiate 1kw of power into a steel box its going to cook something. This has nothing to do with your computer. The cpu clock is running at 1Ghz, but at very minimal power, probably milliwatts. What takes so much current is the 40 million transistors on the cpu. If your athlon suddenly started radiating hundreds of watts of RF I would be worried.

Now I know you people want to overclock everything, but man, CPU's are CHEAP! Why even bother anymore? Now overclocking RAM is a different story... anyone have any luck running PC133 at 133 MHZ on a Microstar 6195 motherboard?

The article brings up the fact that, with Socket A (as opposed to Slot A) chips coming sometime in the not-too-distant future, the whole goldfinger card issue will be more or less moot. Instead, you'll need a device that sits between the chip and mobo, or a "slotket" type device that plugs into an older, Slot A, board. There are, however, pins on the chip die designated for these sorts of things, so it shouldn't be too hard.
I agree that the on-die cache is going to be the most important advance, performance-wise. The L2 cache was running at 1/2 clock, then got bumped down to 2/5 clock at around 700 MHz (due to problems with high-speed L2 cache chip suppliers, I believe). When this goes on-die, the cache will finally be able to run at the full clock frequency, which will make the difference between 800 MHz and 1 GHz look paltry by comparison.
On the whole, though, we may be getting to the sorts of CPU speeds where overclocking no longer serves any useful purpose. A 1 GHz chip (or even a 800 MHz one) can, for most tasks, outpace any other componant of the system. So is overclocking my chip to 1.3 GHz going to make a major difference in my Q3 frame rates? Probably not. The graphics card (yes, even a modern 3D card) became the major bottleneck about 400 MHz ago. Sure, that might let me compile software faster, but in this case, I'm going to go with the rated speed to avoid single-bit errors and the like. Heck, with a chip that fast, I might even underclock a bit, just for the added stability.

Most microwaves ovens operate above 2Ghz, but arent there some modes of water down around 1Ghz?
Also, metal cases for microwave shielding will cost money. What happens when people start skimping on the case, or putting the new 10000Ghz motherboards in their old plastic boxes.
Well, power and frequency are different things, I suppose. But one can still wish for a few exploding heads anyway....
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?
I used to do work with autonomous robotics, using a motorola 68HC11. One day, I needed a pulse at a certain frequency, higher than that of my 8Mhz processor, and I didn't want to use an external capacitor. So, I overclocked it to 50Mhz, slapped on a heat sink and it promptly crashed after 30 seconds, never to get up again. There is a moral to this story, I just can't remember what it is.
Good point. But I was emphasizing the difference between the prior Athlons and the newer ones. Still, you are correct.
I love competition!
I wanted a little more speed from my Columbia Data Products 50lb lugable, and swapped out the 8088 (@ 4.7mhz) for an NEC V20 (@ 8/10mhz?). It worked, and I was happy...for a week or so! (Yes, it's not overclocking...but a brain transplant. Cheap at the time too!)

You posted at #29. So at the time when you made your stupid comment, he was only off by ~3.4%.
Judging by the subject matter and day of the week, I predict that this story will receive at least 150 posts before it is moved off the main page. If my prediction proves correct, than said troll will be less than 1% off his mark.
Any statistician would commend an error rate so low, when applied to such an erratic and unpredictable subject as Slashdot Post-number Trolling. Let us have a round of cheers for our heroic AC, who showed remarkable courage in continuing to post in the face of such amazing odds. Huzzah! Huzzah! Long live the AC! Huzzah!

This Intel vs. AMD 1GHz race is really marketing positioning, or "mine is bigger than yours". Both will allegedly announce 1GHz chips this month, within days of each other (AMD first?), but they will not be available until 3Q. Intel has problems shipping 733 and 750 PIII's, and the latest available _engineering samples_ are "only" 866 MHz. And they were weeked to work. The 933's are not available even as engineering samples. NO ONE has a 1GHz PIII, not Dell, not anyone else. Oh, sure, they are coming, but don't have someone charge your credit card this month for one. ;-)
