Intel's Anti-Overclocking Technology Simplified

John Thorensen writes "Found a fantastic article on Intel's recent Anti-Overclocking patent at Fastsilicon.com. Worth the read, as it also explains some of the technical and ethical issues of overclocking. Good to see that some tech journalists can still write material understandable by an average person."

      Eventually, with all these profit-guarentee laws, its going to be illegal to purchase a competitor's items.

      Sounds depressingly familiar... In the UK, until around 1984, it was illegal to obtain telephone service from anyone other than the (government owned) British Telecom (Kingston Communications in Hull) - governments don't like competition! It still is illegal not to subscribe to the state TV company, if you own a TV: you're free to subscribe to other channels as well, but you have to subscribe to the BBC as well - even if you're in a transmission blackspot and don't receive it! For that matter, until not that many years ago, there were still state monopolies or near-monopolies on everything from milk to steel - and you even had a limit on how much money you could take with you on holiday. Of course, in these days of credit cards, that kind of control would be almost impossible to maintain effectively, but back when moving money meant taking cash or travellers' checks, it was much easier.

      It's always been a reflex of such governments: if "your side" is losing in a market, instead of competing, just tax, restrict or outright prohibit the competitors. In the UK, taxis, pubs (bars) and farm production are all subject to quotas and often price-fixing - no competition allowed! I'm all in favor of proper regulation - food safety, roadworthy taxis driven by non-axe-murderers and non-toxic drinks - but when the government tries to push prices up artificially, or ban competition to bow to political lobbying from taxi-drivers, farmers or bar owners, it's gone WAAAAAAAAY too far. Who can actually say, honestly, that there can be too much choice for our own good?

    What ethical issues are there relating to overclocking? Overclocking a chip, and selling it at a higher speed is already called "fraud". There's nothing ethical or unethical about overclocking. Is redlining your car's engine unethical? Stupid maybe, but that's about it...

This dealer advertised and sold a machine of a specific speed, they didn't sell a system DESGINED for that speed. I know someone who got taken by buying some overclocked machines, when this small buisness owner attempted to sue the computer dealer, the judge threw it out, sayign there was no fraud. If he had said it was a system DESIGNED for that speed it would have been fraud.

  6. How about overclocking detection? by elwinc · · Score: 5, Interesting
    Maybe the fairest thing for Intel to do is find some way to dectect and record if a chip is ever overclocked. The basic problem with overclocking is those unscrupulous folks who drive a chip to it's death, then try and take it in for a refund. If the chip could detect and record warranty-voiding settings, then overclockers wouldn't be able to void the warranty.

    Personally, I'd like to be able to underclock better so it would be easier to built a really quiet PC. Although there are a few articles about it, silent PCs are an underserved area of the market.

  8. Embedding an oscillator by wowbagger · · Score: 4, Insightful

    This technique is nothing more than embedding an oscillator on-chip, and using that to monitor the main clock.

    Since most CPUs internally multiply their clock (you don't feed a 3.0 GHz P4 a 3.0 GHz clock, you feed it a much slower clock and it multiplies it up), why then don't manufacturer's just use an embedded clock and do away with all this?

    Simple - it is very hard to have an accurate clock embedded in the CPU. External clocks can use a quartz crystal to vibrate and make the clock - an embedded oscillator would have to use an on-chip delay line or RC network, which will drift over time, temperature, and voltage.

    So all they can do with a system like this is catch you if you are overclocking by a fairly large amount - were they to try to trap you at a 10% overclock they would have false trips due to process variation.

    To extend the analogy the article used: you will get a speeding ticket if you are going 20 over the speed limit. Keep it less than 10 over and you will be fine.

    NOTE: this is not advice condoning overclocking or speeding! This is just an analysis of the technology involved.

  9. civil disobediance? by SHEENmaster · · Score: 4, Interesting

    Let's start overclocking, enhancing, and reverse engineering EVERYTHING to protest these laws.

    Preventing overclocking is just corportate bs. Remember the liminal messaging of Brave New World, "I'm tired of old things. I want new things. If it's broken, don't fix it. Throw old things away."

    In all honesty, people probably break as many chips as they enhance and overclocking helps profits for chip makers. Anyways, you can use this code, compared against the time/date clock to determine if a chip is overclocked. Software/electronic patents are a bunch of bullcrap for things like this because it's so damn simple to recreate the effect.

      Do you really believe that a product you've purchased should be under the control of the guy who sold it to you? Maybe your car should limit you to the speed limit of the state you bought it in. Maybe women's underwear should have a license forbidding men from wearing them. Maybe when you buy fresh meat it can come with a contract forbidding you from freezing it "to preserve freshness." Maybe Microsoft Press programming books can come with a license prohibiting you from using the knowledge to create competing products.

      Maybe everything should be licensed and nothing sold. Maybe every "manufacturer" should tell you everything you shouldn't do with their product and then warn you in the warranty that they're claiming "no fitness for a particular use or purpose."

      Maybe when your car is leased, all your consumer products are licensed, your food is consumed on the spot at restaurants and your clothes are bought on credit you will really be free. You will be living in the very model of freedom for all the world to see. God bless America.

  13. Too Much Effort, could satisfy everyone: by rkent · · Score: 5, Insightful

    ... An over-clock deterrent mechanism of a chipset which comprises an over-clock detection circuit for detecting over-clocking of a system ... and an over-clock prevention (thwarting) circuit.

    Okay, to implement this, they're including a reference clock on the chip, which means that processors of different (marketed) speeds will have to be made with a different process (which has maybe been true for a long time, but I was lead to believe that, eg in the pIII days, the wafers that failed 1Ghz just got sold as 833MHz, etc).

    So instead of doing all these calculations to decide if you're "speeding," and then doing even *more* calculations to penalize you, why don't they just expose this reference clock speed in a special interrupt call? And maybe even the relation to the operating speed (eg, "you are overclocked by 10%")? Then, they could release an app that would tell you how fast your computer was SUPPOSED to be, and how fast it IS.

    Then, OC'ers could have their cake, and no one else could be taken advantage of by unscrupulous OEMs who overclock to bump up their margins. I concede the point that "most average people will never check anyway," but just having the information *available* should protect Intel from liability, which seems to be the essential idea. Plus, the threat of having the practice exposed at any time should stop at least some of the overclock-resellers.
