Nvidia 55nm Parts Are Bad Too
JagsLive sends in a story (in somewhat inflammatory prose) from The Inquirer, which links to many others; they have been following developments in the alleged NVidia quality "fiasco" for some time. "Hot on the heels of its denials that anything is wrong with the G92 and G94s comes another PCN [Product Change Notification] that shows the G92s and G92b are being changed for no reason. Yup, the problems that are plaguing G84 and G86 are the same that affect seemingly all 65nm and now 55nm NVidia parts ... It is hard to overstate how bad this is. Basically every 65nm and 55nm NVidia part appears to be defective ... We are hearing of early failure rates in the teens percent for 8800GTs and far higher for 9600GTs ... To make matters worse, NVidia has a mound of unsold defective parts that they are going to bleed out into the channel along side of the (hopefully) fixed parts. As a buyer, you have no way of knowing which one you are getting ... Until NVidia comes fully clean on this fiasco, lists all the defective parts, and orders boxes clearly marked, you can't say anything other than just avoid them. Then again, since doing the right thing would likely bankrupt them, we wouldn't hold your breath for it to happen."
Sure, the GPU might be faulty but the rest of the components on their graphics cards (cooling fan, PCI-Express connector) are not showing any issues.
So let's not blow this out of proportion.
I'm a big tall mofo.
At risk or not?
Also, this sounds like a class-action waiting to happen.
This is the kind of story that can only end with somebody being fired for making pizza in the silicon fab oven.
No kidding!!! What do you say at this point?
But they are lead free, which is good for us.

...to buy Nvidia? Problem solved.
If you're a betting man, now's a good time to pick up on Nvidia stock.
The question is, do you feel lucky, punk?
It's been a long time.
I've always secretly been an ATI fanboy... and a traitor since the 6800GT.
Now, I've got ATI again but recommended everyone I know (up until 48XX by ATI) buy the 8800 or 9600....
I wanted ATI to regain some track to even the market... but this is a little much. Complete flops are not good for competition either.
Boot Windows, Linux, and ESX over the network for free.
Basically, the meat packing industry's favourite tactic is that when some contamination, like salmonella is found in the meat they will just sit on it. If the media gets wind of the story, they'll voluntarily recall a small fraction of the meat unfit for human consumption.
At least Nvidia by doing the same thing is not directly endangering human lives...
It takes a man to suffer ignorance and smile
Be yourself no matter what they say
I've got a two 8800 series cards (one 8800GT, one 8800GTS), and I live in a place with no air conditioning. If these cards were subject to heat failure the way the Inquirer has been hollering about - one or both would have died by now. Particularly the one in my wife's computer - it's a Shuttle box, which runs toasty. It's been rock solid, running 24/7 for more than a year now.
I'm not suggesting there is NO problem - but the Inquirer has been talking about this like all of these cards are just waiting to die. With no A/C, and temps in the house above 90F during the summer, they should be dead if the Inq is to be believed. Perhaps I'm just lucky, but I still aint buying the story.

I don't get people who show any sort of devotion to a GPU manufacturer. I just don't. The author of this article is one of them. That doesn't mean it's not true, but he's written a number of articles that later proved to be completely false in the past, for instance saying that the 8800 series would doom nV because of low performance and high power usage compared to the 1900 or 2900, whatever ATI was releasing at about the same time. I'd suggest you not take any article written by Charlie seriously until it's been confirmed (not just repeated, as often happens) elsewhere.

You know what, I think the article is pretty much right on. This is a disaster, and you can bet your ass faulty parts are still being pushed through to unsuspecting users.
I stopped reading when I got to "By Charlie Demerjian."
Seriously, this guy is to NVIDIA as Jack Thompson is to video games. It's just not as common knowledge that you shouldn't take him seriously.
has been proposed:
buy ati.
Good people go to bed earlier.
Why is NVidia using lead-based solders at this late date? The European RoHS deadline for lead-free components was back in 2005. The NForce and 8800 parts were RoHS compliant years ago. Are these NVidia parts even exportable to Europe?
Even though I am an ATI fan (obviously I want nVidia around to drive competition), and I have seen the Inquirer pull off great reports in the past, I still take this with a grain of salt.
First of all, I am not aware of any panic about failed products in the various fora. In cases such as the Red Ring of Death, the Deathstar etc you could not visit a tech forum without having hundreds of people complaining. So maybe the problem is not that big.
Also, the article centers around the fact that they switched from high-Pb solder to a non-lead one. Well, maybe they are switching to environment friendly?
Of course, switching materials a month after launch is highly suspicious. Also, maybe there are failures not at such an alarming rate and also still within warranty so users don't make a big fuss - which would be an indication that a couple of years down the road we might see more failures and out of warranty ones, so it really is a big deal...
Oh, well, we'll just wait and see.
Violence is the last refuge of the incompetent. Polar Scope Align for iOS
Yeah, because the Inquirer is such a steady and accurate news source.
I'll believe this when I see more proof.
The whole thing may well be pretty much balderdash. Then again, we shall see... What really is the point of speculating? Some guy's blog someplace doesn't particularly seem like the height of reliability, then again corps often try to hide dirty laundry. Who knows?
"Malo periculosam, libertatem quam quietam servitutem." -- Jefferson
Okay, i hear about supposedly deffective nvidia GPUs all the time now, but why are we not seeing forums crowded with people with these failed graphics cards? i believe this issue is being overblown substantionally out of it's actual proportions.
To make matters worse, NVidia has a mound of unsold defective parts that they are going to bleed out into the channel along side of the (hopefully) fixed parts.
This sounds very similar to what finally took down Weitek, back when there were a bunch of graphics chip companies competing hotly and being shaken out if they screwed up.
Weitek had built a very fast and powerful chip. But they had goofed: While it had the mandatory basic VGA mode for acquiring the Microsoft certification, there was a bug in it.
QA told management that the bug was there and would fail them. But Software told them a driver could work around it and people would want the chip because it was so fast on graphics rendering. (Of course it could not - because to get the cert it had to work with the stock bootstrap stuff, before a custom driver could be loaded.)
So they went to production with the bug. And the customers got their prototypes, found the bug, and demanded a fix. Eventually they did a fixed version - but had maybe a couple million of the buggy ones on hand and wouldn't sell the fixed ones unless the customer bought some buggy ones, too. So nobody bought and the company folded.

I'll be bookmarking this one, as I can use this information should my 8800GTS fail within it's first two years of life.
I have no idea how the warranty works in other countries, but here in little old Denmark the producer have the burden of proof the first 6 months (normal warranty) and the user the burden to prove that the unit was defective from the beginning the next 18 months after that. This story is pretty much a carte blance for a replacement on nVidia cards. if they fail in any way :-)
SHOULD bankrupt them.
---- Booth was a patriot ----
It is hard to overstate how bad this is.
This will end all life on earth.
That wasn't hard.
William of Ockham had no beard. The most likely explanation is that it was chewed off by squirrels every morning.
Quoting kdawson: "Until NVidia comes fully clean on this fiasco, lists all the defective parts, and orders boxes clearly marked, you can't say anything other than just avoid them. Then again, since doing the right thing would likely bankrupt them, we wouldn't hold your breath for it to happen." I don't suppose the fact that we are now warned of this will have any effect on NVidia's bottom line? I won't be in a hurry to buy an NVidia unit if: a.) there is a good chance it will fry, and... b.) there is a good chance the replacement will fry as well. They need to recall and fix the problem, or they will get bankrupted.
Based on personal experience with the 8800 GT boards, I think this problem is vastly overstated... Running 4 of them in my house, and three friends also running them in SLI config, and no failures. That's with the boards overclocked by a bit.
Additionally, failure rates based on NewEgg reviews seem very low (and we all know people love to post a nasty review if they get a bad one).
The cards do run nasty hot, at least until you set the fan to turn on at something under 180F.... who the hell came up with that turn-on temp?
...for duping the greatest number of people who missed a blatantly obvious joke.
Making a philosophy joke hardly qualifies as "promoting a religion"
No sig for the moment.
I would be willing to risk a card failure, IF Nvidia open source's the software.
If they open source the soft, I will STFU if my card blows up and even if it kills my Main Board as well. I don't want Nvidia bankrupt.
I am even willing to pay the full price.
I just want to NOT have to go through all the crap to install 3D support in debian. Go ahead and snicker ubuntu...
Let's look at 500GB drives, who hasn't been though the crap shoot on those? 500Gigs of data being lost means someone probably lost 300-400 Gigs of data (Who keeps their drive full) How many times have you had a new 500G drive fail in less than a year? For some reason the 120G's didn't have the same failure problem.
Anyway my 2cents
I'm on my second 8800GT now. On the first one, I started seeing lots of "stuck pixels" (actually sub-pixels, because they were only one color) ... but it wasn't the monitor. I was actually able to take screenshots of the pixels, so I figured it was the card and replaced it.
The second one? Same thing happened. Oddly enough, one of those programs that makes the screen blink endlessly actually fixed it up (except for a single green subpixel which I think is an actual monitor defect).
My system is on pretty much 24-7, but I think I have fairly decent cooling. But this would tend to explain the problems I've been having.
That's why I bought XFX cards with a lifetime warranty :)
The Intel 486SX was a defective 486DX who's numeric processor was dead or not working.
Most very very large scale integrated chips have defects. Depending on the nature of the defect, they simply categorize the part differently.
A chip is not fast enough for a high speed gaming system? Us it in an embedded device.
Buy it, if it fails, return it. Just because nVidia has issues you know about, don't think for an instant that ATI doesn't.
Changing solder does not prove a chip is faulty. The parts obviously work to the point that everyone testing them had one that functioned correctly.
There are plenty of reasons (e.g. cost, RoHS) that the change could be made.

Yeah, someday they might actually release the Glaze3D video cards now that they own BitBoys Oy. Hopefully just in time to be able to play DNF on them.
I am neither an NVidia or ATI fanboy (heck, my current GPU is an integrated Intel), but this article is a steaming pile of crap.
Somehow, he takes a report of a routine running change to the production process (a new kind of solder), and magically turns this into some wild tale of how NVidia is shipping thousands of defective parts that will remain in the field.
Completely lacking is how he corresponds the running change to some defect...

I'm not at all sure your criticism is based on the correct quotation source; cf: http://en.wikiquote.org/wiki/Friedrich_Nietzsche#The_Gay_Science_.281882.29 Now back to nvidia....
It appears that ROHS regulations require lead-free bumps, and Nvidia is transitioning the product to lead-free bumps. Where's the defect here?
My buddy was out looking for a Honda Prelude. He found one advertisement that was very much like this. Basically it had
Little to no rust (excellent body condition)
A cd/DVD player
4 LCD screens (headrests, mirror, and passenger)
High-end stereo (speakers/amps/etc)
A blown engine
The guy was selling it for a few grand, and had basically advertised it as "for the value of all the media equipment inside, but you'll need to buy a new engine"
My guess is that the seller "bling'ed" out his car, then drove it too hard and blew a cylinder or a few gaskets.
This is /. for crying out loud. We're all supposed to be geeks, right? This sounds like a solder problem; so, just re-solder the damn chip if it fails. Problem solved... or do we need to revoke a few geek cards?
Dell had high return stats because of the G84, G86. QA is dead and Quality is hard to find. I had to buy a freakin 30 year old vacuum to get a quality one that will basically suck up dirt. Did anyone mention Apple's QA problems...

If you cannot keep politics out of your moderation remove yourself from the Mod Lottery.. NOW!
But they are saying that all chips are bad from like a two year MFG life-span. I'm very surprised that from within that two years that they are saying that they are all bad now... Wheres the proof?... How do you get it to fail and show it fails consistently on every card based on those chips? A CPU/CHIP is very easy to replicate if they are ALL bad (Pentium FPU bug for example).
I mean really, the story came from Inquirer "moles"... Hardly the bastion of reliable information now is it?..
And the actual HP link on the said article (presented as "proof" no less - which made me LOL) is nothing to do with the GPU chip overheating.. its the Mainboard (which granted is nVidia based, but its not the GPU like they are making it out to be) that is overheating due to a bad BIOS profile being put into the notebook originally, if you don't have the issues (which I might add are Wi-Fi loss, total Power failiure and other things - Nothing GPU related except maybe the display issue) and flash to the new BIOS you dont get the issue. HP are replacing the motherboards on affected notebooks. It affects more than just the GPU it affects many things over the mainboard. My wife has one and her Wi-Fi card stopped working... due to overheating caused by a bad BIOS.. once its burned you cant get it back, but HP will swap the Mobo free of charge. It took less than a week for them to repair it and have it back at my house..
Granted I doubt I'll get a nvidia motherboard in a laptop again (I wont in a desktop either for that matter due to NF4 issues with Vista and nVidia's slowness to correct them and even acknowledge that they existed - But that's another story), but to run a story that ALL gpu's are bad with only conspiracy theories as proof, thats just borderline madness..
Its just typical Inquirer, We'll pull a hardware vendor out of the hat and find some minor crap and blow it out of proportion for great Justice and story telling malarky... I read the article, and they are just pulling straws because some "mole" told them some dirt.... They have no proof whatsoever that its the GPU causing any failures.. None... Zip... Nada...
Telling readers to go to the forums to check is stupid too.. Goto Asus's, Abit, DFI's, hell even ATI Forums.. there you will find hundreds and hundreds of users with problems with their boards. Perhaps they should run smear stories on them too, seeing that their products are obviously ALL defective too..??
Besides its currently cool to Diss Nvidia atm it seems.
If you are taking the Inquirer's as the reliable source then I'm sure you think the Daily Star or the National Enquirer are papers filled with facts that are totally true on a daily basis. Hell even The Onion is more truthful than the Inquirer to be quite honest... I'm amazed that some of you take it as gospel.
Once I see a statement from the OEM's supposedly affected by the so-called "GPU" Problem (Funny how it could be a Motherboard issue just like HP claim it is already) or I see some factual write up on it from Ars, or Anannd, or another more reputable site that knows what they are doing, then I'll believe it.. as it is I will take it with a pinch of salt personally. Remember they were SO RIGHT the DirectX10 for Windows XP story too..
j/k
I'll be keeping my tired old 7600 GT for awhile.

This is hardly Nvidia's only recent failure. Vista drivers come to mind. In fact, Nvida's failure to deliver on a key DirectX 10 memory feature (ATI had it running fine on lower performing cards at the time) caused MS to downgrade DirectX 10 such that you don't even need Vista to support it any longer.
And let's not even discuss tessellation in DirectX 10.1 (again ATI has theirs working) and how Crysis downgraded their game back to DX10 after the ATI cards started stomping Nvidia in that hugely difficult to render game with DX 10.1. Were there some payoffs somewhere along the way here?
Nvidia has also missed the boat short-term by betting against GDDR5 in the current timeframe.
A lot of Nvidia shortcomings have been overlooked lately. Hope you weren't any of the people to pay $649 for the first 280GTX cards.
"It's the height of ridiculousness to say for those 9 lines you get hundreds of millions."
Rethink that from a more basic perspective. Are you saying that if you have 10,000 cards, you have an 80% chance of none of them failing?
It is not, actually an independent event. If you are rolling dice, and are looking for a given number, as the number of rolls increases so does the probability of your number occurring in the set of results. Naturally this changes once you roll - but that's not what we're talking about.
[Ego]out
I've always stuck with ATI, even when nVidia is current benchmark champ. I've always found their cards to be rock-solid reliable. Hell the fan on the X800 in the rig I type on now was completely stopped for god knows how long before I noticed, but it's all good up in the hood.
Whether the quality will decline now that AMD's at the wheel, I cannot say.
Hopefully Intel gets into the GPU market in a real way, and soon. Say what you will, Intel parts are nearly always the gold standard of reliability at the consumer level.
Given the BIOS updates by HP and Dell that turn on the fan continuously on the subject notebooks, the reports of higher recalls of these models, Nvidia setting aside $191M in reserve to "deal with this issue", and Dell at least extending their notebook warranties on these notebooks specifically for an additional year, that's a lot of smoke with no fire underneath it somewhere.
"It's the height of ridiculousness to say for those 9 lines you get hundreds of millions."
Agreed, hardcore christians love that "joke" and Ive never really seen it represented without that context.
Could it be some disgruntled employee pissing *just enough* in the mixing vat? Parts get made, marginally pass inspection, then reluctantly are shipped, only to fail due to additional environmentally-related matters? (Just an idea.... once when I was a messing assistant, i watched to my horror a disgruntled sailor remove his shoe, skim it along a pot of soup, and grudgingly and slowly say, "F-U-C-K-I-N-G OFFICERS"...)

Charlie at The Inquirer has no credibility when it comes to nVidia.
From TFA, nVidia is changing from high lead to eutectic (tin) solder - for RoHS compliance - and has issues a PCN to that effect. Charlie has latched onto this as "proof" of his claim that all nVidia chips are faulty and overheat.
What Charlie doesn't explain is how switching from high-lead solder (5/95 Sn/Pb) to eutectic solder (63/37 Sn/Pb) - which has the lowest melting point of all tin-lead solders - is supposed to help if the chips are overheating. Nor does he explain how changing the solder material has any relationship to changing the underfill material on some mobile chips (other than they were both PCNs.) But hey, why let facts get in the way of a conspiracy theory/page hits?

Wow nice job on those 8700M... wait... they must be bad too but since they are sold by Dell they are "blessed" right?
Yeah right, I get all sorts of FPS issues on that card and SLI barely does anything. Time for an ATI.
I have 8800GTS 320MB SLIs. Like your 8600GT I think they are 90nm parts and hopefully are not affected. Other than acting like an effective space heater and sounding like industrial equipment my windows box with those 8800GTSs runs like a champ. It's actually an amazingly stable machine (yes even running windows (XP)) and spews out pixel very effectively. I run full 2560x1600 on many games with few hiccups. I never thought I'd be glad to have older graphics card(s)! But I do look forward to the day I can replace those beasts with one cool running card. I'll be waiting a while for a reliable one it seems.
Oh great. I got two 8800GT OC in SLI... What are the chances that they are both good?
I wonder if we'll ever see graphics card makers use socket GPU's (or maybe it's been done before).
Could be a useful thing if they start coming out with multi-GPU cards... if you can't afford a dual-GPU then add it in later.
Contrary to your belief that 'these kinds of problems are subtle and might be missed during a decent period of testing' it can be EXTREMELY difficult to find these kinds of problems. Beyond your wildest imaginings difficult.
Having worked on high performance hardware/software systems as an engineer I can tell you from first hand experience that the situation is more like there are 999,999,998 ways for things to go wrong and about 2 ways you can get it right, and those 2 ways are not AT ALL obvious. Usually the types of problems you encounter HAVE no obvious cause and no obvious solution and mostly can't be reliably replicated. They can stem from the very most subtle differences between two boards or systems. A cap that happens to be a bit out of spec and a slightly less than perfect solder joint can combine to create an error that happens 1 out of every 100 billion times an operation is performed.
Now, combine that with the fact that you have a dozen vendors slightly varying implementations of a given board design, PCs of all different types and quality levels running at different speeds with different CPUs in them, running a plethora of different versions and subversions of OS and drivers and applications, and the real miracle is you can make a board that works reliably at all.
Any attempt to make a really seriously bullet proof product that would virtually never have problems is simply infeasible. There is a law of diminishing returns involved. At a certain point you have to say "Well, we've tested it in 10 dozen different systems under 6 different OS versions with 128 different apps, and we get N number of crashes/malfunctions per hour of runtime." and then you call it a day. You could spend 10x more time and money on QA and reduce the failures to N/2, but you also won't sell much product when multiply your NRE by a factor of 10...
Plus such perfection will be for naught because MS will release BrokenOS patch "friday the 13th" 2 days later and you'll STILL be encountering the higher error rates. Same goes for new motherboards, games, etc. It is just a loosing proposition.
All you can realistically do is what they do now, test the heck out of it as best you can afford to, ship it out the door, and try to address any issues that come up later as quickly and painlessly as you can.
This is the kind of reason why military and aerospace grade hardware costs 2000x more than electronics with similar functionality with civilian retail/commercial specs. They REALLY do have to be certain things work exactly right or people die, and it is WAY expensive.
"Malo periculosam, libertatem quam quietam servitutem." -- Jefferson
I think you have no credibility when it comes to nVidia. I don't see a single mention of RoHS in the article. I'd also point out that eutectic solder is not RoHS complaint. RoHS complant solder is less then 0.1% lead (Outside of medical devices and monitoring equipment). Eutectic solder is 37% Lead. It seems to me you're just making stuff up.
Given the BIOS updates by HP and Dell that turn on the fan continuously on the subject notebooks, the reports of higher recalls of these models, Nvidia setting aside $191M in reserve to "deal with this issue", and Dell at least extending their notebook warranties on these notebooks specifically for an additional year, that's a lot of smoke with no fire underneath it somewhere.
The part of this article unrelated to the widely known evidence you cite, and the part that I will take a wait-and-see approach to, is the claim that every single nV 65 nm and 55 nm GPU is defective. On the other hand, net chatter makes them sound very stable, and there are far fewer complaints of broken 8800GTs than there are of 4870s (one of which I own, and mine is fine). I'm guessing that he's making a big overstatement with his claim that every single 55 or 65 nm nV GPU is defective.
"I zero-index my hamsters" - Willtor (147206)
I bought a nVidia 8600GT in December 2007 - no issues here... it hasn't failed and I haven't seen one graphics related BSoD on Vista (seen several BSoDs due to other things, like a corrupted registry, but never anything relating to the graphics). Does the failure suddenly appear, or is there any kind of early warning signs?
Multiple stories directly attacking consumer confidence and affecting purchasing decisions for your product?
If this story weren't true, nVidia would have sued The Inq right off the face of the Earth by now.
In this example, the chance of one card failing is 20%. But we are not interested in just one card. We have two cards, therefore there are four possibilities: the first card fails, the second card fails, neither fail, or both fail. If we are interested in at least 1 card failing and the only condition that doesn't include at least one card failing is "neither fails" then we can use the property 1 - P[neither fails] to make the calculation simpler. If neither card can fail, then the probability of neither failing is 0.8 * 0.8 = 0.64 and of course 1 - 0.64 = 0.36.
If you want to go the harder way you would need to calculate the P[1st card failing but not 2nd] + P[2nd card failing but not 1st] + P[both cards failing] = P[at least one card failing]. That calculation would be: (0.2 * 0.8) + (0.8 * 0.2) + (0.2 * 0.2) = 0.36.
If that doesn't make sense then let's take a step back and say we have two coins and each coin is equally weighted so the probability of a coin landing heads or tails is exactly 1/2. If we flip one coin the probability of at least one coin being heads is therefore 1/2. If we flip two coins, the probability of at least one coin turning heads isn't that simple. There are again four possibilities: the first coin can be heads, the second coin can be heads, neither is heads, or both are heads. Therefore if each is equally likely then the probability of the first coin being heads but not the second is 1/4, the probability of the second coin being heads but not the first is 1/4, and finally the probability of both being heads is 1/4. So the probability of at least one coin being heads is 1/4 + 1/4 + 1/4 = 3/4.
Still doesn't make sense? Draw it out on a chart:
coin 1 heads | coin 2 heads | probability of outcome
No 1/2 No 1/2 1/4
Yes 1/2 No 1/2 1/4
No 1/2 Yes 1/2 1/4
Yes 1/2 Yes 1/2 1/4
If that's better for you, then the chart for the graphics cards would be:
1st card fails | 2nd card fails | probability of outcome
No 0.8 No 0.8 0.64
Yes 0.2 No 0.8 0.16
No 0.8 Yes 0.2 0.16
Yes 0.2 Yes 0.2 0.04
nVidia needs to take a page from Intel's FDIV days (ca. 1993) and just do a no-questions-asked recall and replace.

Good.. I thought it was just me. And I'm definitely NOT a hardware guy. But I can't see, from his description of the PCN, how switching from high-lead to tin solder could be seen as a response to, well, anything except "let's use less lead".
I know that 63/37 has a lower melting point than 60/40, and a "sharper" one (no pasty phase), which is why I use it for audio repairs and cabling; I'm a klutz, and anything that makes my solder joints more stable is good. But I can't imagine that this matters as much on SMT, where your components are fixed in place.
That said... a quick Google shows that there are all sorts of considerations in what solder to use for PCB solder bumps: not just temperature, but the metals involved in the leads, and the PCB traces, and a bunch of other stuff that involves knowing more about electronics and metallurgy than my "the batteries go this way" brain can handle. So there may well be some stability advantages to eutectic solder for NVidia's solder bumps.
Anyone here actually know this stuff? I've got an 8800GT in my Mac Pro, which definitely runs hotter than your average PC...
I own two notebooks with Nvidia Chipsets in them. Both HP notebooks, one contains an 8400M the other an 8800m GTS. The 8400M notebook's cover broke at the hinge conection (a problem that was in no way related to circuit boards) last week and was sent back, just got it back today and checked on the repair slip was a note that they replaced the outside cover but they had also replaced the video circuit board. Surprise!
Just last week the Laptop with the 8800GTS started blue screening windows with a video subsystem problem before the login prompt. Ubuntu booted without error but would freeze every 30 seconds for 15 seconds or so if you moved the cursor on the screen. HP concluded the graphics system was malfunctioning and off to repair it went. I'll know in a couple weeks what was replaced but I bet the 8800GTS gets replaced.
This is a BIG deal people. Charlie is being a sensationalist but it's a BIG deal if HP extends the warranty on every laptop with the chips in them for an additional year. HP wouldn't do that unless they feared loss of customers or a class action lawsuit because the warranty extension costs them serious dollars. And I would also bet HP isn't going to eat every dollar. Nvidia will share the cost at a minimum. Even 10% bad parts could cost Nvidia hundreds of millions.
Charlie might go overboard in his complaints about Nvidia but he's right about this issue, it's really really big and Nvidia will eventually talk about it because of stories like this. Without Charlie's stories Nvidia would probably try to bury the issue and pretend it wasn't happening and if I was invested in NVDA I would want to know this information because it's a harbinger of a profit warning by NVDA.
Woooooooooooosh!
APK quotes people (including myself) without context and should not be trusted. Just thought you should know.
The CDC says 1.4 million americans are infected every year.
Deaths caused by salmonella in persons per million:
US: 0.0946797, which places #39 ;)
Norway is at 0.217723, #33
Luxemburg has more than 4 ppm (!) and gets first place
Denmark 1.4
Germany 0.8
Oh, and South Africa has 0.090. Slightly less than the US.
So it would seem that salmonella is more prevalent in Europe than in the US.
Stats from CDC/NationMaster
Purchased an eVGA 9800GTX+ from newegg few weeks back, and I have to say I'm anything but dissapointed. The card works fantastic, without overclocking, out of the box. I've never had it run more than 7 degrees warmer than it runs when windows loads, and even then the fan only kicked up to 75%, and the cooling took about a minute once I exited.
All in all, from my personal experience, the card is fantastic, and I'm not going to be concerned with this guy's fear-mongering. I was so pleased, in fact, that I turned around and bought a 22" widescreen just so I could get a higher resolution.
Don't worry if you're a kleptomaniac, you can always take something for it.
I've had an 8500GT (G86) since December. I'm now counting down the days until it goes kablooey. Yay.

Me !pass (english || boolean logic)? That !unpossible.
I have a PNY 9600GT. I basically can't play Unreal Tournament 2004 because I get the black screen of death every 5 minutes or so. PNY said they wouldn't do anything for me because I haven't seen the crashes in UT3.
I'd just like to take a moment to point out that citing a "x%" failure rate is a meaningless number.
Everything everywhere has a 100% failure rate - over a long enough timespan. At the opposite end, you've got the DoA rate, which is generally really low. So, over what time span are they claiming a 10-20% failure rate for nV chips? 1 month? 1 year? "lifetime" ( = product lifecycle)
I stand corrected. If not RoHS compliant, eutectic solder is a step towards adopting lead-free solder - and as stated, nothing to do with the alleged overheating problems.
There is a better article here:

Re inquirer articles - just cause the messenger wants them dead doesnt mean their message is incorrect.
The real problem is only going to show once the laptops are out of warranty as the customer will then have a choice of discarding the laptop or usually around $500 for a new motherboard. I imagine people will be quite angry.
TFA and /. summary are possibly grossly unfair. There *are* two sides to every story, and apparently the article author has a chip on his shoulder for Nvidia, no pun intended. (Personally, I don't have a dog in this fight, but in the interest of fairness...) Check out the comments, like this one which would seem to be from someone at Nvidia:
Answer this... As you know Charlie has a history of severe bias against NVIDIA. Our July announcement of the problem with notebook GPU failures (link) has given him lots to rant about. This new story is the latest in a series of articles in which he continues to stretch the truth in order to spread FUD. In it he asserts he paints the notebook chip failures as if it were a widespread epidemic affecting every single NVIDIA GPU in existence including desktop. Here is a list of BS and the truth.
Myth 1 - NVIDIA has denied responsibility for the failures and is blaming suppliers and partners.
In our announcements accept responsibility for the failures. We DO call out the material failure but we also acknowledge that our suppliers and notebook designs because this is true and we need to disclose this in our official statements to the SEC. We would not go on record with the SEC making such bold claims if they weren't true. See our Form 8-K statement below.
Myth 2 - There is an "official story" that the problems were limited a batch of a few bad parts for HP.
We have never issued a stated this. See our public statements below.
Where is source for that?
Myth 3 - NVIDIA is forcing a fix on notebook makers
The idea that a supplier like NVIDIA can dictate a fix to the world's largest PC makers is preposterous.
The truth is the notebook makers determining their own course of action and we are supporting them.
Where is source for that?
Myth 4 - NVIDIA is trying to cuts our financial liability.
We put aside $200M to help partners solve this problem for consumers. As far as we know NVIDIA is the first and only chip maker to help fund the cost for repairs.
Myth 5 - This affects desktop chips, G92, G94, etc.
We have only seen this problem on notebooks. We just reiterated this during an official financial call. Once again we would not say this if it wasn't true. Note we have not disclosed the specific GPUs but we have stated this impact previous generation GPUs and that current gen GPUs are not in production.
Fact Charlie has an obvious bias against NVIDIA and he has no sources to back up his claims. Out of all of the hundreds upon hundreds of notebooks models designed with NVIDIA chips in the last few years, only a small number of these have experienced the problem. Within this small number of models, only a small percentage actually experiences the chip failure. It is highly unlike a notebook user will experience the problem. And we have never seen this problem on desktop.

"Separately, NVIDIA plans to take a one-time charge from $150 million to $200 million against cost of revenue for the second quarter to cover anticipated warranty, repair, return, replacement and other costs and expenses, arising from a weak die/packaging material set in certain versions of its previous generation GPU and MCP products used in notebook systems. Certain notebook configurations with GPUs and MCPs manufactured with a certain die/packaging material set are failing in the field at higher than normal rates. To date, abnormal failure rates with systems other than certain notebook systems have not been seen. NVIDIA has initiated discussions with its supply chain regarding this material set issue and the Company will also seek to access insurance coverage for this matter."

So, whichever way it breaks, I do hope that what *is* the truth WRT this issue gets out...
"...there are some things that can beat smartness and foresight. Awkwardness and stupidity can." ~ Mark Twain
Considering the limited number of cards I will own in my life (say no more than a 100), I have had 1.5 fail on me this month from NVIDIA, and I have never had any video card fail on me in my life.

We're at an impasse here, maybe we can compromise.
Eh... I have been running my 8800GTS G92 for the last 8 months, cycling every day (sometimes multiple times per day... I try to save power whenever possible) and I've had zero issues...
The card goes from 70C (at peak) down to 15C at night and back up in the morning. (My computer room has an open window and has gone through Winter, Spring, Summer and now into Fall)
So far no issues... besides, it has a lifetime warranty and I'll be buying a replacement mid '09 ANYWAY.
How do we know for sure this report is correct, and not an attempt to try to bankrupt Nvidia by some 3rd party.. All we have to go on is hearsay and no real facts. That's the problem with internet, a lot of people actually believe everything that is posted on it, which ofcourse a lot of times is just wrong information..
Or just do the right thing by making it expensive to not have it anything but military/aerospace quality.

Which do you want? A $3000 perfectly reliable video card or a $150 video card that is 99% reliable? You probably don't have $3000 to spend on a video card. I know I don't. If you do, then chances are you can get what you want, but also be prepared for it to be 5 years out of date, because no amount of NRE will make such a product come out of the pipeline fast.
Beyond that it is really a false choice, because the hypothetical $3000 card will only BE 100% reliable if you also buy only the motherboard, power supply, etc that it can be guaranteed to BE 100% reliable with, and only run the OS and apps it is guaranteed to work reliably with. Even then nothing is 100% reliable. Eventually your perfect card will drift out of spec just a bit and 1 time out of a billion some edge of some signal won't hit the bus inside some timing window in some obscure condition and you'll have a crash.
I helped design, test, and verify avionics systems on practically all major commercial airliners put in service in the '90s. The systems we designed and built are safety of flight critical systems. Those systems are designed, verified, built, and tested to literally the highest standards known to engineering, every bit as stringent as anything you'd find inside a nuclear reactor. Yet STILL we occasionally ran into scenarios with equipment in use in the field where the function of the system was compromised by failure scenarios which simply could not be fully anticipated. The cost of those systems was enormous. No retail grade product could ever conceivably achieve even that level of reliability and still be worth the cost.
So really, what you're effectively saying is 'if we can't have a perfect video card, we should have none at all'.

The general reckoning seems to be that the issue is thermal expansion rates, not melting point - see, for example this article which someone linked elsewhere in the thread.
After seeing a decent size of hardware go my way, I'm not sure 99% is even reachable. For $500-700, that card had better last 2-3 years and still be at least a middle-of-the-road performer.
What we get now are mostly cards that are built towards (versus against) failure. It'd be time to take a page from Korea and make it too good to want to return(by making electronics returnable for about any reason). That is how quality can be turned around.
There is the occasional nod to hardware reliability, it is seen in companies that have largely gone under(SGI, pre-acquisition 3dfx, NCR before they went to clones, and DEC to name a few). Perhaps some would want to know that swapping out hardware does take time and money.

Is to not buy cutting edge hardware. Any time you go out and buy the latest super duper brand new shiny high performance stuff you're a lot more likely to get something unstable or potentially defective than if you go for the middle of the road stuff.
The high end stuff is always by its very nature pushing the hairy edge of the power, thermal, process, etc envelope. Thinking back I've purchased 5 video cards in the last 12 years or so. All of them worked flawlessly. For that matter I still own 4 of the 5 and 3 of them are still in service and working fine. None of them ever failed.
Seems to me I never had really serious driver issues either. Certainly the drivers always steadily improved to the point of being pretty near 100% reliable. The NVIDIA Quattro card I'm using now works great. I had maybe a half dozen crashes really early on. Nothing since then.
I think hardware manufacturers are certainly obliged to TRY their best to make a reliable product, but if people want to be able to play really demanding 3D games at high res then they're also going to have to be willing to deal with the fact that cards required to do that are going to be less stable. It is a tradeoff. Nobody forces people to buy a 9800 GTX, they could settle for a lower end card if they wanted better stability. That being said obviously it isn't either good business practice nor good ethics to sell a product which is useless or known to be seriously defective.
Sounds to me like NVIDIA ran into an engineering problem with certain products which I am guessing was pretty difficult to uncover before the fact, and now they're doing the right thing and backing those products. I guess it remains to be seen as to how well they do that.
