Gráfica Nvidia Reports Problem With Laptop Chips

Bom, vamos lá limpar a confusão:


- Os chips afectados são parte de um lote específico de 8500M GT/8400M GT -bus de 128bit, GDDR3, 16 sp's-, vendidos a certos OEM's de Taiwan (os 8400M G e 8400M GS, 8600M GS, 8600M GT e 8700M GT, 8800M GTS e 8800M GTX não foram afectados).

- O problema está no "packaging" que foi fabricado com solder points defeituosos pela TSMC -manifesta-se pelo elevado consumo eléctrico, resultando em calor excessivo-, não na die do chip gráfico propriamente dito.

- O "write-off" de entre 150 e 200 milhões de dólares para compensar os fabricantes OEM pelos RMA's a curto prazo está coberto pelo seguro de fabrico, pelo que a Nvidia será re-embolsada a médio prazo.

Que eu saiba eles n deram detalhes quais foram os modelos que foram afectados.

Assim como o que dizes está errado na parte do reembolso dos 150 milhoes a 200. Eles vão TENTAR colocar sobre o seguro, mas não dão certezas se ira ser aceite.

Well, duh...
O seguro já existia. Não podes fazer um seguro sobre alguma coisa e receber a indemnização depois do problema ter ocorrido, ou podes ?
Quanto aos modelos afectados, a notícia do Digitimes, embora incompleta, também tem o essencial.
 
NVIDIA: Let’s spread the blame far and wide
Last week I blogged about a problem that had emerged relating to a ”significant quantities” of older mobile GPUs suffering premature death due to heat exhaustion. Well, since then the company’s stock has taken a serious battering, and the company doesn’t seem to be willing to talk about the problems with its GPUs publicly. Instead NVIDIA has resorted to blaming the suppliers, blaming the OEMs and also blaming the customers for actually using the GPUs.

Here’s the current official line from NVIDIA:

“While we have not been able to determine a root cause for these failures, testing suggests a weak material set of die/package combination, system thermal management designs, and customer use patterns are contributing factors.”

OK, check it out:

* “… testing suggests a weak material set of die/package combination …” - Blame the suppliers
* “… system thermal management designs …” - Blame the OEMs
* “… and customer use patterns …” - Blame the customers

Oh, and NVIDIA is in the clear … or is it? See, I find it hard to accept that this issue has anything to do with the suppliers. Why? Well, are you hearing other stories of defective components coming out of TSMC (Taiwan Semiconductor Manufacturing Company)? Any mass recalls? No, which is why I’m certain that this isn’t a supplier issue. If it were a supplier issue, the problem would extend well beyond NVIDIA.

But what about the OEMs? Did they screw up? After all, the thermal management design of notebooks (that is the cooling) is down to the OEMs, right? Well, yes and no. OEMs build notebook cooling systems based on the specs that they get from the CPU and GPU makers. If this were a design issue then you’d expect a few models to be affected and the damage to be limited. What we are in fact seeing are OEMs such as HP releasing BIOS updates for a whole raft of models, such as this one which covers HP Pavilion dv2000/dv6000/dv9000 and Compaq Presario v3000/v6000 series notebook PCs. What’s this BIOS update do?

The new BIOS release for your notebook PC is preventative in nature to reduce the likelihood of future system issues. The BIOS updates the fan control algorithm of the system, and turns the fan on at low volume while your notebook PC is operational. If you are currently experiencing any symptoms on your notebook PC, please contact HP for support.

So what about customers, are they to blame? No. In fact, this is purely preposterous and shows the lengths that NVIDIA are willing to go to to dodge the blame. Without some third party application the end user has little control over the running of the cooling fan in a notebook. Sure, someone might block off the air vents by running the notebook on a bed or put it away in a notebook case while still running, but these would be isolated issues and certainly wouldn’t require NVIDIA to take a charge of up to $200 million to fix.

NVIDIA, it’s time to come clean about this issue.

All Nvidia G84 and G86s are bad

Comment No word on MCPs yet


THE BURNING QUESTION on everyone's mind is what Nvidia parts are failing in the field? No GT200 jokes here, NV personnel are still quite sensitive about that, but our moles have told us about the bum GPUs.

The short story is that all the G84 and G86 parts are bad. Period. No exceptions. All of them, mobile and desktop, use the exact same ASIC, so expect them to go south in inordinate numbers as well. There are caveats however, and we will detail those in a bit.

Both of these ASICs have a rather terminal problem with unnamed substrate or bumping material, and it is heat related. If you ask Nvidia officially, you will get no reason why this happened, and no list of parts affected, we tried. Unofficially, they will blame everyone under the sun, and trash their suppliers in very colourful language.

The press is totally stonewalled, but analysts are quite another story. If you call up with Wall Street credentials, they will tell you what is going on, but unfortunately it doesn't seem to be entirely accurate. What analysts tell me they were officially told is that it is a specific batch of parts that only HP got.

The official story is that it was a batch of end-of-life parts that used a different bonding/substrate process for only that batch. Once again, the trusty INQUIRER bullshit detectors went off so loudly that the phone almost vibrated out of my hand. More than enough people tell us both the G84 and G86 use the same ASIC across the board, and no changes were made during their lives.

When the process engineers pinged by the INQ picked themselves off the floor from laughing, they politely said that there is about zero chance that NV would change the assembly process or material set for a batch, much less an EOL part.

On the less technical side, multiple analysts also told us that NV specifically told them that this problem is confined only to HP. I wonder why Dell is having failures in huge numbers for their XPS lines and replacing them with ATI parts? Why is Asus having similar problems? Go check the message boards, any notebooks that came with G84s and G86s have boards filled with dead machine problems. Most of these, especially on the NV forums are being quashed and removed by admins, so act quickly and take screenshots of your posts.

Basically, NV seems to have told each analyst a highly personalised version of the story, and stonewalls everyone else who asks. Why? The magnitude of the problem is huge. If Dell and HP hold their feet to the fire, anyone want to bet that $200 million won't cover it? This has all the hallmarks of things the SEC used to investigate in a time before government was purchasable.

The other problem is the long tail. Failures occur due to heat cycling, cold -> hot -> cold for the non-engineers out there. If you remember, we said all G84s and G86s are affected, and all are the same ASIC, so why aren't the desktop parts dying? They are, you are just low enough on the bell curve that you don't see it in number that set off alarm bells publicly yet.

Laptops get turned on and off many times in a day, and due to the power management, throttle down much more than desktops. This has them going through the heat cycle multiple times in a day, whereas desktops typically get turned on and off once a day, sometimes left on for weeks at a time. Failures like this are typically on a bell curve, so they start out slow, build up, then tail off.

Since laptops and desktops have a different "customer use patterns", they are at different points on the bell curve. Laptops have got to the, "we can't bury this anymore" point, desktops haven't, but they will - guaranteed. The biggest question is whether or not they will be under warranty at that point, not whether or not they are defective. They are.

If you look at the HP page, the prophylactic fix they offer is to more or less run the fan all the time. Once again, for the non-engineers out there, fan running eats a lot of power, so this destroys the battery life of notebooks.
Basically, people bought a machine with a battery life of X, and now it is Y to prevent meltdown from a bum part. It doesn't fix anything, it just makes the failures take longer, hopefully past the warranty period, at a huge battery life cost. Fire up your class actions people, you got shafted.

Back to the engineering, we intoned that this was a cover-up of engineering failures by Nvidia. We also said that they probably knew what was happening. Think we were kidding? Read this, twice, linked again here for those that can't move their mouse to the left, it is that important.

If we knew a year and change ago that these exact parts had heat problems, think Nvidia did? Think the voltage difference between A02 and A03 is coincidence? This is a classic example of not meeting engineering goals and overclocking through brute force (voltage bump in engineering terms) to compensate.

HP and the others were blindsided by this, it happened far too late in the design cycle to compensate, and it looks to have been covered up hastily, badly, and eventually fatally. Blaming suppliers, OEMs and users is completely unfounded and says that NV is unwilling to properly address this issue, only hide from it. NV knew, they made silicon changes to fix another problem that directly lead to this problem.

Nvidia is covering this up, hard. All the usual sources are keeping mum on the topic with only a few daring to speak out. Given the sheer magnitude of this, their marketshare for notebooks was huge in the period, this could very well suck up most of their remaining cash. Don't underestimate how bad this is going to be for NV, we highly doubt $200 million will even begin to cover it.

A Nvidia desenha substratos agora ?
Além de escrever tretas, é um ignorante daquilo que diz.

Isso é mentira, o site original desmentiu que houvesse problemas, embora o jantar entre o Charlie e o director de marketing da Nvidia, Derek Perez, tenha acontecido realmente.
 
so para fazer um sattus da situaçao :
nao se sabe ainda se existem modelos especificos afectados(falou-se ai nas 8600gt), so se sabe que foi a geraçao 8.....?
e nao se sabe bem que patch sera essa que foi fornecida as marcas de portateis nem o que faz e se teremos acesso a isso ou nem por isso?
nem como identificar se a nossa grafica sofre desse mal?
em suma é isto?
 
Existe desenvolvimento nesta noticia?
Eu tenho um hp com uma 8600m gs,e o portátil tem dois meses.
Já houve alguém aqui do forum com problemas?
 
NVIDIA ConnectorGate Issue

Sauces close to a gypsy convoy in Kazakhstan have indicated that at least one Dell sales service team in Eastern Europe is confirming further details of the “weak die/packaging material” inconvenience that’s apparently afflicting masses of computers with NVIDIA graphics and chipsets.

If that belief was based on having to put right issues only with NVIDIA based notebooks, then how much will the cost scale if NVIDIA’s partners desktops need fixing too?...

Other HEXUS sauces have confirmed that NVIDIA is set to make an expanded official statement in the coming hours.

Epá estava mesmo a pensar comprar um portatil novo com 8400GT mas assim...não quero aquecedores, problemas e barulho e parece que neste caso arrisco-me a levar com tudo...fdx
