NVidia Puts the Kibosh On Overclocking of GTX 900M Series 138

An anonymous reader writes Nvidia surprised members of the overclocking community this week when it pulled OC support from drivers for its 900M series mobile graphics cards. Many users (particularly those who bought laptops with higher-end cards like the 980m) were overclocking – until the latest driver update. Now, Nvidia is telling customers not to expect OC capabilities to return. “Unfortunately GeForce Notebooks were not designed to support overclocking,” wrote Nvidia’s Manuel Guzman. “Overclocking is by no means a trivial feature, and depends on thoughtful design of thermal, electrical, and other considerations. By overclocking a notebook, a user risks serious damage to the system that could result in non-functional systems, reduced notebook life, or many other effects.”

      because quite often it takes a lot of effort to identify that the cause was user overclocking, by then the customer has complained to the store, many stores have policies of replacement or money back in first X days. While it definitely should be a try it at your own risk situation, the reality is people will basically lie to the retailers face saying they did nothing and expect a refund/replacement.

        NVidia are merely doing what Intel did with clock locking. And for the same reason: they don't want people getting a cheaper card and overclocking it, they want people to buy the most expensive card.

        OC doesn't lead to catastrophic failure in the first year unless the system already has a fault that would appear in a few years of normal use. This is how they test MTBF: stress test and see failures, scale back to the rate of normal use to get the mean time before failure.

        However, that means that without OCing, the system would last on average longer than the manufacturers' warranty,which they scale so that they don't have many failing during that time. Add in that most won't have the receipts more than a couple of months and their fear is that OCing would get some warranty returns within the period they have kept the receipts for.

          The real problem with OCing and failure, is that when a failure does occur sometimes you can't tell it has occurred. Part of the chip just stops working that might not be critical to the system. It's near impossible to tell this has happened without a lot of analysis that the average person overclocking is simply not capable of. Just because it happens to "work" when you first do it does not mean you aren't causing irreparable damage.

        • Except that these are an "M" (for Mobile) series, not a card, but a chip. Also not something you buy individually, but rather what comes with the laptop, and makes the entire thing useless if it burns out.
          For desktops, you can add cooling to support the OC, and if you do burn out the card it can be replaced. Few laptops support hardware upgrades or replacements for GPU.

        • If that were the case they'd limit it on everything, not just mobile GPUs. Clock speed is just one of the ways Nvidia differentiates cards, and is usually the one with the least overall effect. It's far easier and more effective to disable pipelines in the card's firmware. Plus it gives the added benefit of binning parts that have faulty hardware (you just turn off the faulty parts instead of throwing out the whole GPU). This isn't about "making people buy the most expensive card".

            It takes the offender out of normal society and and puts them into a society full of criminals. It gives them a record to make it more difficult for them to integrate into normal society. it makes the best possible effort to ensure that they reoffend.

            The only reason for locking someone away is if they are a danger to society. Since most people locked away in the US are not a danger to society, we have a nation of sadists. And, as the prison system is privatised, an industry of businesses profiting from sadism.

              That's a good reason but it's not the only reason. Punishment also acts as a deterrent to those who would commit crime and helps to balance the scales of justice by ensuring that there are consequences for bad action. Currently we use imprisonment way too frequently and the system is poorly designed but that doesn't mean there is no appropriate use for it.

And don't even get me started on so-called "white-collar crimes, which are as a rule *far* more damaging, and in practice carry few if any penalties.

Unless, of course, you are planning on them just rejecting warranty claims because it is 'unlikely' that it is their fault. OIn which case they might as well not include such a charade and just claim that it is 'unlikely' any problem is their fault and reject all warranty claims.

                You're thinking of an overcurrent protection fuse. An eFUSE, however, could probably be used for exactly this situation (permanently marks that the device has been overclocked) without the risk of accidentally triggering.

                  My point is that EVERY legitimate warranty claim is the result of something happening that should not have happened. So here we have a proposal to deny someone's warranty claim based on the fact that an eFUSE or whatever said they overclocked the chip, when in fact the state of the eFUSE itself could be a defect. That makes no sense at all.

                    I don't know... I see your point, but I'd wager that the likelihood of a false positive on the eFUSE is less likely than the user actually overclocked it to trigger it. It's kind of like those 'water damage' stickers they have in phones. Maybe it's possible that it claims damage when there wasn't any, but it's sure a good indication that something happened that wasn't supposed to, and it makes it harder to lie your way into a warranty replacement.

      • This is basically the reason. And also, in my opinion, overclocking a laptop is dumb anyway. Laptops do not have the cooling necessary for this type of thing - they typically run really hot as is. If you have a huge full ATX tower case and a video card with 3 extra fans on it, sure overclock.

      While people like to claim of course they did nothing wrong, I am sure people who cook their laptops overclocking them will always try and point the finger back at NVidia...
      Hence, they are playing it safe.

      Desktops have MUCH better cooling systems, and hence are much less likely to suffer from extreme temperature problems...

      I suspect it is also a sign they are pushing the limits harder - remember, new generation GPUs have built in 'overclocking' in the form of dynamic clocks already,
      so they are using up the headroom they had more effectively. This means you are more likely to be pushing past a limit, and less likely to notice (until too late).

      They will always wear the fallout from such peoples actions.. so they have obviously decided right now the risk is not worth the reward.

      • NVidia was even hammered when they released a chip on HP and Lenovo Thinkpads that was overheating and resulted in a significant reduction of the lifetime of the laptop and never took responsability for it. So, this is half bullshit since NVidia never replaced all the chips and never paid the cost of replacement to HP and Lenovo for selling these chips to them. The customers did complain to HP and Lenovo, and only a bunch of them got a replacement. They used the serial number and expiration date of the warr

        The Quadro FX1500 and some other chips had a die bonding problem. nVidia failed and they knew it, and what's more, the downstream OEMs knew it. I had an HP Elitebook with FX1500 graphics, which died the death of a thousand dogs amen. It took me literally over 24 hours of phone time to get a replacement because fuck you, HP, that's a name for a sauce, not a computer company. But what really clinched the deal was that I found out during the course of the problem that this was actually a known problem, techs inside HP (the high-end ones, not just phone monkeys) actually knew of the problem. And this was a laptop with an MXM video card, so they could have replaced them. But since this is HP, they didn't do that. And no manufacturer will, which is why paying extra for your notebook's video card to have an MXM connector is a boondoggle. In theory, they can replace just the video card. In practice, that costs too much, they will just replace the whole machine if you can get them to admit that they made you a lemon.

        So yes, nVidia just fucked up. No, I never OC'd my mobile Quadro. Yes, that's the part of the PC that died, before the HP "tech" came out and killed it the rest of the way (it would work until it heated up, before that) with static, days after I called. That's what your on-site three-year warranty from HP gets you. Fucked.

      It does apply to desktops, but there are several significant differences... like: 1. Desktop users have control of over ways to manage heat that they can't with laptops 2. If a desktop user fries their graphics card, they only have to replace their graphics card. In comparison, integrated graphics cards are permanently attached to the motherboard which typically also has a BGA processor soldered on. That is three components needing to be swapped out if the user screws up the graphics card from using a feature that has no use case. 3.

      if Nvidia provided the capability and it caused the damage they might wind up liable for the damage, wether from a suit or a manufacturer making them cover repairs.

Under US law at least, there are implied warranties for "fitness for a particular purpose", which a company cannot always disclaim once that company has implied them (this varies by state to some extent). A good example is a pickup truck that comes with a ball hitch and is shown in the TV

        • I have a friend who has basically killed two laptops overclocking them, he then takes them back and demands they are faulty

          Your friend is kind of a selfish dick.

          yes he is. But that is hardly a rare condition. He justifies it by saying they wouldn't put the feature in their if it wasn't meant to be used, therefore it is their fault.

          He has a point; absent the manufacturer saying not to overlock or the warranty is void. Is it any different, in principle, than a manufacturer letting you run the CPU at a higher clock rater in "Turbo" mode and if it fails saying "tough luck?" I can see why Nvidia pulled 2015-02-16he capability since they probably never intended for it to be used because it can cause problems and leave them open to repair claims.

        After NVIDIA's refusal to step up to the line and assume their financial responsibility for causing so many laptops to die of thermal stress in previous generations, I feel no empathy for them. I DO have empathy for the rest of the people in the supply line that are getting dicked over by your friend, just not NVIDIA.

    I can see why they are removing the overclock feature on graphics hardware in very tight spaces with little in the way of cooling options so I really don't understand why this is a story.

      The 980M in my Clevo P650SG overclocks by 125MHz with ease - and it won't even hit 70C while playing games in that overclocked state either. When you're playing at 3K (there's also a 4K screen available), that extra 125MHz makes a noticeable difference.

      Removal of overclocking from the drivers is irritating at best.

        Yes but what about that cheap and nasty Acer or similar shit brand which is already pushing the limits of it's cooling instead of having a safety factor in the design. BBQ!

          The cheap and nasty Acer will throttle when it gets to 70C, overclocked or not.

          The water outside here isn't frozen. I'm in the southeast of the UK, where we've had a generally mild, largely snowless winter - it's 8C as I write this, for example. Not that that matters, as most of us have central heating and the temperature indoors won't be anywhere near as cold as it is outside!

            That would almost make sense if we were talking about desktops, where the user can replace the GPU. That's typically not an option in a laptop; even if the GPU is designed to be replaceable, it's oft not designed to be upgradeable, or the manufacturer doesn't make parts available. And I say almost because anyone who cares about having the fastest laptop GPU on the block enough that they overclock their laptop GPU will run out and buy one of the new models that has a GPU that comes from the factory running a

              FWIW, the sort of laptops for which this is an issue (ie high-end gaming laptops) typically have graphics cards on MXM modules, they're designed to be upgradeable to the latest and greatest.

              The *price* of those modules, however, means it's not something most owners will ever do...

      It would be fine if they were simply removing OC support on new cards. The problem is that they are removing a feature from a product that has already been sold, and even used as an advertising point by some manufacturers. This is no different to Sony removing OtherOS from the PS3.

    Those notebooks were not meant to produce that performance, it may be capable, but: - NVidia does not want to deal with fried GPUs, to decide/prove if it was because of the overclocking or some manufacturing problems - Suffer the negative PR on the market if too many of their systems seem to die ahead of time or suffer from heat/related issues.. Apart from some rare exceptions notebooks were never meant to be in the same performance category as desktop configurations, this should be taken into consideration this when buying one.

    This is all about warranty repairs.

    Less than bright people overclock their laptops to unsafe levels, laptop dies after 6-12 months and ends up on the laptop manufacturer's repair table. No way to conclusively prove it was overclocked, so they end up picking the tab for the hardware abuse.

    Laptop drivers have allowed overclocking for a good while, so it must be that some recent generation NV chip had unusually tight margins and there is a noticeable spike in warranty claims, or just some big laptop manufacturer not wanting to deal with the headaches of overclocking-related support/warranty incidents is suddenly pushing NV to solve he issue on the driver level or lose business.

    High end GPUs have always had fairly tight thermal margins. Even more so on laptops. The age old problem of packing really high performance silicon into laptop form factor with tiny heatsinks and small fans. Sure, they could just downclock the chip by 20% and have a nice, cool laptop that... would lose to the competitor GPU and really mess up the sales of the chip. So they push it as far as they possibly can... and the tight margins on laptops just can't do any meaningful overclocking without completely replacing the cooling - which is not really doable in a laptop.

    At least on NV side you generally can always install the "generic" laptop driver and get the latest driver bits. On AMD side there are many laptop manufacturers that outright block the generic AMD graphics drivers for ~reasons~ and you end up with a piece of hardware that has effectively an unsupported GPU - laptop manufacturer cannot be assed to update the GPU driver and generic drivers do not install (unless modded).

    Does no-one remember the 8800M GT?
    Damn fools used low melting point solder on them and they failed worse than Windows ME.
    They never have and never will specify decent cooling.

      The problem was not the melting point of the solder. It was fatigue cracking. The switch to a different type of solder has tradeoffs, everything always does. The same solder was used by both Nvidia and AMD at the time. In Nvidia's design of a series of GPUs of the same age someone got

  • You can't control the power supply or heat dissipation on a laptop. So yes, you'd be a complete idiot to overclock one. You'd almost have to not even know how overclocking works to even attempt it.

    I had a dell XPS15 model with a manufacturing defect that made the computer crash when running games, the only way to solve it was to underclock the GPU. No it was not overheating, it was a manufacturing problem, there are several accounts of this problem on the net.

  • I am sure this is based on some analysis of failure data. Regardless, this is a bad move when people are already cooling off on discrete graphics, especially on laptops. Intel integrated graphics will now run many games adequately on small screens and there are obvious cost/form factor/battery life advantages. If you don't cater to hardcore gamer/technology enthusiast market that is most interested in overclocking, just who is going to buy your chips and cards?

      I would guess that market is small enough not to worry about any impact on sales. If including discrete graphic chips is important for mainstream sales manufacturers will use them in some higher end systems; if not then they are on the way out wether or not they can be overlocked.

  • From a technical standpoint, it seems like the ideal solution is to have some programmable ROM that users can blow to indicate that they have accepted any harm that comes from clocking it beyond what the design (heat/voltage/lifetime) allows. That ROM would have to be queryable via a tamper-proof BIOS or EFI hook so that stores could verify that it is intact before accepting returns.
