Lawsuit Claims Nvidia Execs Concealed Serious Flaw 219

snydeq writes "A lawsuit filed in a California court on Tuesday alleges Nvidia concealed the existence of a serious defect in its graphics-chip line for at least eight months 'in a series of false and misleading statements made to the investing public.' The lawsuit contends that Nvidia CEO Jen-Hsun Huang and CFO Marvin Burkett knew as early as November 2007 about a flaw that exists in the packaging used with some of the company's graphics chips that caused them to fail at unusually high rates. Nvidia publicly acknowledged the flaw on July 2, when it announced plans to take a one-time charge of up to $200 million to cover warranty costs related to the problem. That announcement caused Nvidia's stock price to fall by 31 percent to $12.98 and reduced the company's market capitalization by $3 billion, the lawsuit said. The lawsuit seeks class-action status against Nvidia and unspecified damages."

    I had an nVidia 8800GT card fail prematurely early this summer. I was pleased with its performance, other than the failure, so I picked up the newer version of the same card, from a different manufacturer. Unfortunately that was the middle of June :(

    So odds are high that this card is going to die early too. And of course I don't have receipts for either card at this point, but if there's a chance at recouping some of my investment, I'd sign up.

        Sorry, this is the law suit for duped stock buyers, not duped product buyers. The duped product lawsuit is in room 12.
        Past the joke, if it makes it past the warranty period you have little regress as a customer. While it's illegal to say "we're doing great" while knowing your main product line is failing from a security law point of view, unless the failing parts are in a safety critical application (e. g. child car seats) there is no law mandating a recall/replacement/settlement for selling a crappy product.

          $1200?

          There is your price of "portability".

          As a former mechanic, it always pissed me off when auto manufacturers tried to force customers to dealerships for repairs by making the components so difficult to repair that even independent mechanics could not fix them.

          The dirty sekret is that the dealerships couldn't either. They simply resorted to part-swapping to confirm their half-assed diagnosis(manufacturer flow charts(Step 14: Replace with known good part), NOT actual testing).

          The end result was that the independents were made to look like bumbling idiots("Your gunna have to take it to the Dealer...") after actually trying to find the problem, while the Dealership makes the money just by throwing parts at the problem (at customer expense).

          I HIGHLY suspect that your a victim of that same process. One good reason to AUTOMATICALLY suspect your bill when there is more then one component replaced. If there was, more then likely, the first part didn't fix it, but the second did, and they want to get paid for the time it took to install the first part, so they simply tell you one part "took out" the other.

          This is one of the reasons I am a FORMER mechanic. From a moral standpoint, I simply could not be a party to the deception that is all too prevalent in the business, and quit.

      So odds are high that this card is going to die early too.

      Did you buy a card with a lifetime warranty? Both EVGA [evga.com] and XFX [xfxforce.com] offer lifetime warranties on 8800GTs. Personally, I won't buy RAM or video cards from a company that doesn't offer a lifetime warranty, as there are more than enough manufacturers for both products offering these warranties. My current 8800GT is an EVGA, and it's nice knowing they're on the hook for this flaw if it happens to strike me. The card manufacturer has probably spent millions on Nvidia silicon, so they have clout to extract some compensation from Nvidia, whereas I do not.

They also offer a step up program for like 3 months. This means if you buy a card, and then a new model comes out, or you buy a lower end card and decide you need more power, you send back your old card, pay them the difference, and they'll give you the new one.

      which specific chips are effected?

      No one knows for sure, and Nvidia isn't telling. The Inquirer says practically [theinquirer.net] all [theinquirer.net] of them, but their author has a history with Nvidia so there's quite a potential for bias there. The running theory is that the problem is due to thermal properties of a substrate material. This substrate material supposedly expands and contracts at a different rate than surrounding material in the chip package. Over time, this stresses the silicon or solder points, eventually causing a failure of the part. Laptop parts are definitely affected, you only need to look in notebook manufacturers forums and you'll see an incredible number of posts from owner of notebooks with, for example, 8600 GT mobile parts.

      Desktop parts may also be affected, since they're all based on the same core silicon with (supposedly) the same substrate materials. It's possible that the problems aren't as apparent (at least not yet) due to the different thermal conditions you'd see in a tower chassis compared to a notebook. The very popular 8800GTs out there may start failing en masse in three months, six months, a year's time, or maybe never. Because Nvidia won't specifically say which parts are affected, whether it's all the parts or only certain manufacturing runs, etc., we have only speculation and rumor to go on.

      • If you never shut off the machine would you be safe from this? If it's a problem with some things expanding quicker than others when things heat up, it seems that leaving the machine on all the time, thereby keeping everything at relatively the same temp, would help to mitigate any effect this might have on the parts. I have ATI cards in both of my machines so I'm not worried about this either way but my desktop machine is on 24/7 unless the power goes out which is very ra^@$%$%@$#@

        1. A dirty little secret of all governments, the USA included, is that they _can't_ get rid of unemployment or inflation, and they're actually trying to keep both where they want them. There's this funny little hyperbolic-looking curve called the Phillips Curve [wikipedia.org], which ties inflation to unemployment. If you even tried to push one to zero, the other rises sky-high.

        So the best any government can do is to keep both at a point they can live with. Exactly what that point is, that's a matter of political debate and position, but everyone tries to do that. A mean most used is the interest rate. That's what the federal reserve does in the USA, but other countries have their own similar institutions.

        (The corolary being that any politician which harps on unemployment and inflation as proof that his opponents are evil, or worse yet, promises to really solve either or both, is himself a liar and has no scruples telling you lies to gain power.)

        So, yes, a bunch of people without jobs _are_ what makes the economy work. (A capitalist economy included.) Because without those, you'd get a hyperinflation comparable to interwar Germany. (Just as a comparison point, not saying that that's the same cause.) And conversely, if anyone actually managed to eliminate inflation, like some idiots demand, most of you would be out of job.

        2. Well, actually, the reluctance to make people change jobs was arguably one of the (several) reasons the Soviet economy colapsed. They were very reluctant to kick people out of a job, since the whole theory was that everyone should be given a job in communism. So if they made a hammer manufacturing company, and 20 years later there would be more of a need for wrenches, they'd still keep a bunch of people there making hammers, just so they don't kick them out and tell them to find another job. It's not the only factor, of course, but worth thinking about.

        Or seen at another level, they wanted to eliminate both the unemployment _and_ inflation (via price controls) which had the same devastating results as when it had been attempted before. If both can't take their natural positions on that curve, something else has to give. In their case, productivity went down instead, and corruption went out of hand. Which effectively is another way to get inflation, only in a much more destructive way.

        3. The whole thing about capitalism and the free market is that it's an optimization algorithm. It's really a genetic algorithm, based on semi-uninformed trial and error. The "genes" (processes, ideas, products) which are closer to optimal survive and are copied by others, and the process repeats, moving it all closer to the optimum. The genes which lost, and the companies which bet on them, die. Sometimes spectacularly, leaving a bunch of people temporarily unemployed.

        That's how it's supposed to work. Bit wasteful, no doubt, and stressful for those who end up looking for a new job. Scott Adams of Dilbert fame (who, I might add, is actually trained as an economist, so he might understand these things) claimed in a blog post that it's "harnessing the power of stupidity" and that at any given moment, 80% of society's resources are pushed off a cliff by idiots. But somehow it seems to work better than anything else we've tried. Trying to prevent that optimization cycle from happening, deviates from optimum very quickly, and produces even worse results.

        It _is_ what makes capitalism work.

I've yet to even hear about any campaign along the lines of, "ok, we'll create more jobs, but you'll pay them for them out of your savings, which will depreciate quite a bit faster." Nor, "ok, this inflation sucks, we'll must fix it! Oh, by the way, a bunch of you will lose your job for that." ;)

    Now I'm no electrical engineer but when you take a working chip and put it in a machine it seems a little odd to blame the packaging it came out of for higher than normal failure rates if it works initially.

    Maybe "packaging" refers to the way the actual chips are placed into the material around them? Although it seems like a very odd way of wording it as to me packaging implies something that is discarded.

        However, the shielding causes the boards to overheat when in use. If the end-users would actually RTFM, they would clearly see that they are supposed to scrape off the top 0.01" on all ICs after disca

      An actual microchip is absolutely miniscule. The ceramic(or plastic, or meta) that holds it and contains the pins that get soldered to the board is called packaging.

      Chip packaging refers to the part around the silicon. In your stereotypical chip, it's the gray 'body' that the pins emerge from.
    • Each chip is actually just a really thin slice of silicon with extra impurities added in important places. This small slice of silicon is quite fragile and doesn't really have an interface that you can easily connect to. So they put this slice in a "package" which is usually plastic or ceramic but occasionally metal. Then they use very thin gold wires to connect points on the silicon slice to pins that come out of the package. Then the package is sealed. The package exists to protect the fragile silicon sli
    • The slice of silicon wafer that makes up the guts are the 'chip'. The black piece you can see with the wires sticking out of it, and with the wires inside that connect to the actual chip is the packaging.
    • For a while now, chip packaging has referred to the material around the chip. Also the packaging can be used as a name for the board interface to the chip as the pin assembly is considered part of the package. One current Intel desktop chip packaging for Core 2 Duo is LGA775 [wikipedia.org] or Socket T. Package is sometimes overlooked as a factor of chips but it is important. For the MacBook Air, Apple worked with Intel to shrink the package 60% to fit into the very small motherboard.

      nobody else caught your request for 'non-layman's terms' so here goes:

      Chip Scale Packaging (CSP) Technology
      The information presented in this chapter has been collected from a number of sources describing CSP
      activities, both nationally at IVF and reported elsewhere in the literature. The most important of the former
      being the Chip Scale Packaging Task Force, an international multi-client programme carried out between
      1996 and 1997 and a project work carried out by two students at Chalmers University of Technology..
      D1. Introduction to CSP Technology
      D1.1
      Definition of CSP
      Originally, CSP was the acronym for Chip Size Packaging but very few packages are of true chip size.
      Therefore, the acronym is today usually used for Chip Scale Packaging. According to IPC's standard J-STD-
      012, "Implementation of Flip Chip and Chip Scale Technology", a CSP shall have an area of
      no more than 1.2X the area of the original die size and is direct surface mountable [D1].
      D1.2
      Description of various types of CSPs
      In contrast to most other package types, the name of the package type, "Chip Scale Packaging", contains no
      information about how the package is constructed, except for that it shall have approximately the same size
      as the chip. Therefore, CSPs include component types with probably more dissimilar characteristics than
      any two other IC package types clearly manifesting the inaccuracy to look at CSPs as a homogenous group.
      Some packages look like miniaturised BGAs which names like miniBGA and BGA indicate. Others have
      leads which give them properties similar to conventional leaded packages such as PLCCs. For this reason,
      CSPs are often classified based on their structure. At least four major categories have been proposed [D2].
      These are: flex circuit interposer, rigid substrate interposer, custom lead frame, and wafer-level assembly.
      Examples of packages of these categories are given in Figure D1.

      D1.3
      Driving Forces for using CSPs
      The main driving forces for using CSPs are:
      Improvement in performance
      Size and weight reduction
      Easier assembly process (compared to bare die attach)
      Lower overall production costs.
      Of these, reduction of size and weight are probably the most important factors for initial adoption of CSP
      technology. Consequently, consumer products like camcorders, mobile phones, and laptops are among the
      products that have been first to utilise CSPs.
      D1.4
      Advantages and disadvantages using CSPs
      Chip Scale Packaging combines the best of flip chip assembly and surface mount technology. It gives
      almost the size and performance benefits as bare die chip assembly, at the same time as it offer the
      advantages of a encapsulated package. CSPs can be standardised, tested, surface mounted, and reworked.
      So far most CSPs have been produced for applications with rather low number of I/Os but many types of
      CSPs can be produced with large number of interconnections. However, before CSPs with large number of
      I/Os will find widespread use, techniques for producing reliable low-cost high-density printed boards must be
      developed.
      The advantages and disadvantages of CSPs depend on what one compare with, standard surface mount or
      bare die assembly. Due to the large spread of characteristics for various CSPs, it also depend on the type of

      No, you certainly are not. Packaging is all the stuff around the silicon. It's not the wrapping paper and the big red bow on the gifts under the christmas tree.

  • If nVidia is spending $200 million to cover these faulty items under the warranty, then why file a law suit? If your card is out of warranty, then nVidia has no legal obligation to fix it. That's what a warranty means. It might be frusrating, but if they warrant the item for 1 year and it fails in 3 years then I don't see why they are liable.

    Of course, I have one of these bad chips in my MacBook Pro, so hopefully it will fail within the 2 and a half years I have left and they will fix it. If not, I'll b

Yeah Nvidia can and has cut prices to be competitive, and bye bye profits since you are, at best, now selling those cards at cost.
