NV G9系列再爆缺陷问题/戴尔XPS升级SSD[08-14 09:14:02]出处：pconline作者：lifan责任编辑：danding
希望是传言！NV G92/G94也爆瑕疵问题
前段时间，NVIDIA的移动显卡存在瑕疵不仅使得其股价大跌，也使得不少下游笔记本厂商不得不应对消费者的质疑。但一切似乎并没有结束，质疑声又出。
NVIDIA要小心陷入一招不慎，招招被动的局面
这次的质疑声来自于四家未透露姓名的主板厂商，这些厂商称G92和G94核心的GPU出现了高频率的瑕疵问题，包括台式机显卡和笔记本显卡类型。
具体的型号有8800GT，8800GTS以及8800GS，部分8800 mobile 显卡，大部分的9800系列显卡以及少部分9600显卡，这些显卡都基于G92核心。而对于G94核心显卡，则只有9600GT受到影响。
当然，这些显卡是否存在瑕疵还没有得到NVIDIA的官方确认，因而并不是板上钉钉的事情， 但是“一朝被蛇咬，十年怕井绳”，谁又不担心这次的传言是真的呢？
今日观点:相信NVIDIA的市场公关部门应该最近是手忙脚乱了，不仅消费者要安抚，各笔记本厂商也要安抚。当然NVIDIA的研发以及检测部门更应该受到批评，为什么会有如此多的瑕疵设计产品流入市场，这是值得好好检讨的。对于笔记本消费者而言，尽量购买没有瑕疵问题显卡或者问题已经得到解决的笔记本为好。

Nvidia G92s and G94 reportedly failingDesktop boards this time

NVIDIA IS IN DEEP trouble over the defective parts problem,and from what we're being told, this is only the tip of the iceberg. NVstill insists on stonewalling and spinning because the cost of owningup to the problem could very well sink the company.
If you haven't been following the story, the short version, up till now, is that all G84 and G86 chips are bad. Nvidia is blaming everyone under the sun, but denying they have any hand in the failures.While this may sound plausible, technical analyses by people intimatelyinvolved in the requisite semiconductor technologies tell The INQ thatit is a bunch of bull: NV simply screwed up. Badly. If it was a problemwith the suppliers, NV would not be paying out more than the chip cost, much less gagging OEMs: it would simply be passed along.
In any case, the official story is that there was a small batch ofparts given only to HP that went bad. That was comprehensively provedwrong when Dell, Apple, Asus,Lenovo and everyone else under the sun also had problems. NV ARrecalled the parts and recanted the story about it only being an EOLtest run. Bad fibbers, no cookie. They still stuck to the story aboutit being only laptop parts, and that it was under control.
If you think it is under control now, the following is part of an emailsent Monday by a very tech-savvy reader. "We just got our firstcasualty from the Nvidia mobile graphics [expletive deleted]. Laptopused by one of our senior engineers started acting up this pastweekend. Won't boot except in SAFE mode. Called Dell, they tried a fewthings, gave up, stated it was the graphics module, and said thatbecause they were SO swamped dealing with that issue, they were justgoing to send a completely new laptop!"
There are two messages here whi**ave echoes in earlier emails receivedover the past few weeks. First is that Dell is replacing full laptopsover this, contrary to what they claim (read the comments here and herefor more). The second is that the small 'under control' problem is farfrom that. If they had a handle on it, they would not be so far behindand drowning in backorders. Anyone want to bet Dell isn't going to getstuck with the bill here?
To make matters more laughable, the fix that NV is forcing on Dell, HPand everyone else does not fix the problem, it simply makes it lesslikely to occur during the warranty period. With HP now offering anextended warranty period, and Dell looking likely to do the same, thiswill only multiply the cost. Add in the fact that Nvidia is sending outdefective parts as replacements (there are no good ones), and you havea recipe for a long and expensive tale.
That is where we stand now - NV is simply stonewalling everyone and thecosts are adding up. How adult of them. The question of why stillremains though, and with another little tidbit of information, itbecomes quite clear. There was a digitimes article on July 25, hereif you are a subscriber, that said: "Due to Nvidia not clearlyexplaining the details of the faults reported in its notebook GPUs,some channel vendors have demanded graphics card makers issue a recallfor desktop-based discrete graphics cards using the same GPU core,according to sources at graphics card makers."
Reading that, it sounds a mite odd: why would Nvidia keep the partnersin the dark like that? They have to be told what the real story is forbusiness reasons, right? When you see stories like these, it is verylikely that they are not what they seem, and that the story is simply anice face-saving Asian '**o' applied with a backhand.
A little digging revealed what this, and more, is all about, and it'sfar uglier than just the 'notebook' version. It seems that four boardpartners are seeing G92 and G94 chips going bad in the field at highrates. If you know what failures look like statistically, they follow aPoisson distribution, aka a bell curve. The failures start out small,and ramp up quickly - very quickly. If you know what you are lookingfor, you can catch the signs early on. From the sound of thebackchannel grumblings, the failures have been flagged already, and NVisn't playing nice with their partners.
Why wouldn't they? Well, the G92 chip is used in the 8800GT, 8800GTS,8800GS, several mobile flavours of 8800, most of the 9800 suffixes, anda few 9600 variants just to confuse buyers. The G94 is basically onlythe 9600GT. Basically we are told all G92 and G94 variants aresusceptible to the same problem - basically they are all defective. Anyguesses as to how much this is going to cost?
From the look of it, all G8x variants other than the G80, and all G9xvariants are defective, but we have only been able to get people tocomment directly on the G84, G86, G92 and G94, and all variantsthereof. Since Nvidia is not acknowledging the obvious G84 and G86problems, don't look for much word on this new set either - if they canbury it, it will drop their costs.
In the end, what it comes down to is that the problem is far biggerthan they are admitting, and crosses generational lines, process lines,and OEM lines. Nvidia is quick to point the finger at everyone but themselves,but after a while, the facts strain those cover stories well pastbreaking point. There is a common engineering failure here - thisproblem is far too widespreadfor it to be anything else. The stonewalling, denials and partnergagging is simply a last-ditch attempt at wallet covering.
With OEMs extending warranties, Nvidia is going to have to cover a lotof laptops for a long time. Desktop boards are going bad as well now,contrary to the statements of Nvidia PR and AR, and the hole keepsgetting deeper and deeper. I wonder if they can ever come clean andsurvive. µ
