A DOCUMENT HAS COME TO LIGHT that details the lengths to which Nvidia has gone to cover up the problems it has been having with its graphics chips.
The most recent lawsuit against it by the National Union Fire Insurance Company (NUFI) claims the company has withheld information on the nature of its bad bumps. The very same information it has withheld from us or any other nosy hack or awkward analysts.
The story was broken by a certain Mike Magee at TG Daily on Friday, and it has a lot of juicy bits. The short story is that the list of defective chips shipped by Nvidia goes back to the NV4x generation, and the list of OEMs affected counts ten and basically includes every Nvidia customer.
NUFI complains bitterly that Nvidia has been covering up essential information it is entitled to receive as Nvidia's insurer by refusing to disclose even the most basic facts about the company's GPU chip failures.
We had the same complaint. Let's go back over what happened so you can see the depths of this debacle.
On July 2, 2008, Nvidia issued an 8-K report that essentially said: "We have a big problem." But then it got really vague. Its 8-K mentioned devices "in certain versions of our previous generation MCP and GPU products used in notebook systems." Nvidia also claimed that it didn't know why the problems were happening, saying, "We have not been able to determine a root cause for these failures." But was sure that it had fixed them. No, really, it said so quite explicitly. "All newly manufactured products and all products currently shipping in volume have a different and more robust material set," it stated.

Nvidia chips show underfill problems
**************************EXCERPT*****************************
Bumpgate Electron microscopes reveal a lot
WHEN WE TOLD YOU about the 'bad bumps' in the Apple Macbook Pro 15-inch models the other day, we expected it to end there.
But as luck would have it, Nvidia pointed us to a much deeper problem that not only affects at least some of the Macbook Pro notebooks, but likely every other high Temperature of Glassification (Tg) underfill chip Nvidia makes.
Technical Background
To understand this article, you really need to understand the problem, so please read the technical three part series (Part 1, Part 2 and Part 3) explaining what the problem is and where it occurs.
Nvidia's current problem stems from its half-hearted response to its earlier problem by only changing the underfill. Nvidia said that's what it did, both near the end of our initial Macbook article and in a later Cnet article here.
In that, Nvidia's Mike Hara said, "Intel has shipped hundreds of millions of chipsets that use the same material-set combo. We're using virtually the same materials that Intel uses in its chipsets." Note the word 'virtually'. The problem with this statement - other than his analogy being misleading and not addressing Nvidia's chip design problem - is that 'virtually' in this case means Nvidia missed a key coating component in its revised chip engineering design. It is NOT the same material-set technology as Intel, AMD, ATI and everyone else we talked with uses. Unfortunately for Nvidia, the coating material it left out is critical for the life of the chip.
Before we break out the electron microscope again, we feel the need to point out some of the things that Nvidia managed not to talk about in its purported explanation of the fix. It is sad to have to point this out, but underfill does not crack, bumps do. The bumps that cracked did so for a long chain of reasons that are explained in my earlier three-part article linked above.
Earlier article:
Why Nvidia's chips are defective
**************************EXCERPT******************************
Part One A long and complex story
This the first part of a series of three articles getting to the nub of Nvidia's graphics chip woes. The series is the result of months of research conducted by diligent INQhack Charlie Demerjian, despite an in-box stuffed full of abuse. Part two can be found here and Part Three is here.
NVIDIA HAS RECENTLY been saying a lot about how it's chips are not bad, and giving people reasons about why the problem is contained. Unfortunately, these disingenuous half-truths don't stand up to an explanation of why this problem is happening.
Sounds like a design rule violation on the passivation layer or lack there of.
Nvidia continues to have problems with its fab vendor and/or communication.
And another article:
Nvidia recommends not buying its defective chips
And they call this bumpgate
****************************EXCERPT***************************
Bumpgate Told ya so
IT LOOKS LIKE Nvidia finally has a solution to the defective chips fiasco that it keeps covering up. The short story according to documents seen by VR-Zone is to not buy them, just buy the newer ones.
No, really, we're not kidding. To quote some of the latest memo, ".....NVIDIA strongly recommends that customers transition to this latest revision of the NB8E-SET GPUs as soon as possible. These latest revision units utilize "Hitachi" underfill packaging material that improves product quality and enhances operating life by improved thermal cycling reliability." We know what you are thinking, there is no problem with the chips, they said so. Many times. With a straight face.
Then again, we did say we believed otherwise. And then Nvidia denied it. And so we printed copies of the technical docs on the problem that we saw, note the part about Hitachi underfill and the date. And once again Nvidia denied it. We publicly mocked them, and so Nvidia spun harder. Whee, look! The shreds of the company's credibility are twitching!
My HP Laptop does have an Nvidia card but doesn't get much usage.
Got to figure out what is in it....since this is the first I have heard of this problem...
[Rumour] AMD to release Evergreen Mobile chips in January 2010
******************************EXCERPT***************************

Following Nvidia's leaks of its "next-gen" GT 300M series, Nordichardware reports that ATI's DX11 mobile cards are arriving in January 2010.
Quite honestly, I think this is really all about their insurance company not wanting to pay up. It is, afterall, solely based on claims made by them, and no one else, released to the media, and then made public.
nVidia gave them all of the information they requested, and now, the insurance company, National Union puts out a statement saying nVidia “flooded National Union with technical data”, and now they want different information. Information nVidia doesn’t have access to, and so they can’t give it to them.
They have been maneuvering and positioning themselves into a position of being able to get a court to exempt them from any liability.
Which is, exactly, what they’ve done.
“So National Union doesn’t want to pay up. It wants the court to declare it has no duty to indemnify Nvidia because Nvidia has breached the terms of the agreement.”
This isn’t about chips, it’s about money. Typical of insurance companies, they want their premiums, but they sure as heck don’t want to pay out on policies.
I live by the old Jamaican saying...”stick to da evil wot you know best, mon”. I’ve had problems with ATI, and I’ve not had any problems with nVidia. For me, the decision is clear.
Please do note that nVidia has stepped up and replaced all of the alleged cards, it’s money that the OEM’s want for lost business, labor, and suffered reputation, that’s in question now.
I have a hp tx1200 notebook, was a beautiful, good laptop, 8 months into ownership, it dropped wireless then it dropped video. HP replaced the motherboard underwarranty, that fix lasted 8 months or so and did it again. I barely got 2 years of service out of this laptop and I swore off hp for ever. I usta buy only hp’s. I know its not totally their fault but they should replace/fix these issues not say that you are reading blogs and they never heard of an issue with the tx1200. they cant help it when their suppliers screw them over but they sure as hell could help out their customers. I have bought to Asus’s now to replace my hp’s
I wanted to add both of my asus laptops have nvdia graphics cards but they are asus mxm, removable so if they do crap out you can replace them. even tho one of them is a gaming laptop it gets very hot but supposedly it was designed to run 100c and it gets very close to it during gaming. these have been out about a year and half I hadnt heard of them failing just lots of complaints about it being a scorcher.
I’ve had a string of GTX-280 cards just go purple screen of death.
No idea if it’s the same problem or not, but the new generation of ATI cards is better anyway.
Acute for laptop products.

Reading thru the papers,...sounds like to me there was a real engineering problem.
No argument about that.
But, IMO, the insurance company is making it out to be a major catastrophe. Tell me, which manufacturer hasn’t had their own issues and had to replace tons of stuff?
As a consumer, I really don’t care who pays, as long as it’s not me. What’s important is that the consumer doesn’t pay, and is not brought into their internal machinations. Yet the insurance company chose to do exactly that.
This is bad for everyone.
Our other choice is ATI grapics chips and what I’ve seen is that drivers/support with those guys isn’t nearly as good as the luck I’ve had with NVIDIA.
Any other opinions here on NVIDIA/ATI?
