INQ指NV的芯片组也出现严重缺陷

Nvidia chipsets are defective too
BumpGate Only 630, 7050, 7100 and 7150 changed for no reason

LOOKS LIKE THOSE wacky folk at Nvidia are at it again, changing perfectly good chipsets for no reason. If you recall, they changed the G86 parts and the G92/G92b as well, for no reason.

Luckily, the firm seems to be spending money like there is no tomorrow, it has nothing to do with the fact that they have a few warehouses full of defective chips, they seem to want to keep their validation engineers fully employed this time of year for no apparent reason. This time, the chipsets being changed are being changed 'just because', and the bump material has nothing to do with crapping out. Really. This, this and this are vague guesses.

So, with that, we bring you word of the next PCN, this time for chipsets, or 'motherboard GPUs' if you are terminally stupid enough to believe the marketing hype.
Because this one is no different from the other two PCNs linked above, we will skip the detailed description and just bring you the pertinent details. Should you want the formatting, it is still here.

This little ditty is called "MCP73 Products Change Bump Material from High Pb Solder to Eutectic Solder"", and is confidential, NDA'd, and has a June 2008 date. The PCN # for the pedantic is PCN0353A. Nothing new there.

Page 2 has a more exact date of June 13, 2008, with a PCN submit date of June 13, 2008 as well. Planned Implementation Date is July 25, 2008, and Proposed First Ship Date for change is August 17, 2008. This means that the parts should be hitting the shelves about now, so if you want to buy a low performance MCP, you can buy in moderate safety now. It is still a Class 1 change.

The list of the affected parts is: NF-630I-A2, NF-7050-610I-A2, NF-7050-620I-A2, NF-7050-630I-A2, NF-7100-630I-A2 and NF-7150-630I-A2. It looks like this is an admission that there is absolutely nothing wrong with the 630, 7050, 7100 and 7150, they just are changing them just because. No need to panic, really.

Page 3 has the same diagram as the G92 PCN, and the same reasoning, to enhance package robustness. We guess they can't use the term failure, defect, or crib death in a PCN. Odd really. In any case, the qual data is available now, with samples going out on July 18, 2008. Eutectic bump products will be marked with a trailing R on the lot #, but no box marking for underfill this time.

The document ends up on a humorous note. There are two different dates, a generic June, and June 13, both 2008, earlier in the PCN. On the page 4, they have 7/11/08 listed for Revision A, the initial release. Come on guys, a little proofreading here and there wouldn't kill you. It would kill us, but you guys have the pretence of professionalism. µ

EE Times:

Fabless business model 'stressed out,' says analyst
Nvidia reportedly not getting enough 55-nm capacity from TSMC

SAN FRANCISO—Nvidia Corp. is not getting the 55-nm capacity it needs from silicon foundry giant Taiwan Semiconductor Manufacturing Co. (TSMC), a problem likely to worsen as the graphics chip maker moves to the 40-nm node, according to Doug Freedman, an analyst at American Technology Research.
In a report published Thursday (Sept. 11), Freedman wrote that the "fabless business model seems to be getting stressed out" and that the Nvidia-TSMC relationship "sounds problematic" and "needs to evolve."

In order to minimize its own risk, TSMC is building less capacity as it ramps new technology nodes, according to Freedman. TSMC doesn't get enough visibility from its smaller customers such as Xilinx Inc., Altera Corp. and Broadcom Corp., Freedman wrote, so the foundry cannot take the risk of building new capacity to support larger customers. Nvidia is TSMC's largest customer, he noted.

TSMC's board of directors last month approved a $795 million capital spending plan that includes a push into 45-/40-nm CMOS processes and MEMS.

Last month, Nvidia reported second quarter financial results which included a charge of $196 million to cover a recall of faulty chips. An Nvidia spokesman initially blamed TSMC for the recall, due to a ''weak die/packaging material'' in select devices. The spokesman later recanted, saying Nvidia "worked closely with TSMC on packaging and the material.''

On Tuesday, a New York law firm said it filed a fraud class action lawsuit on behalf of Nvidia investors accusing Nvidia of failing to disclose "unusually high failure rates" or mobile video adapters. The suit, brought by Shalov Stone Bonner & Rocco LLP, names Nvidia, CEO Jen-Hsun Huang and Chief Financial Officer Marvin Burkett and alleges that they issued a series of misrepresentations and omissions relating to the failure rates of the recalled chips.

According to Freedman's report, none of the chips shipped by Nvidia were bad. Some chips were being run at cycle times that were too high for notebooks which led to packages cracking, Freedman said. According to Freedman, the parts Nvidia was shipping were good, but being run in the wrong notebooks.

Freedman also said Nvidia underestimated Advanced Micro Devices Inc.'s latest graphics chip offerings, including the price and performance. Nvidia cut its own prices to stop market share loss, which appears to be working, Freedman wrote.

Last week, Tristan Gerra, an analyst with financial management company Robert W. Baird & Co., said TSMC is seeing orders down substantially in the fourth quarter and could see its manufacturing utilization rates drop to their lowest percentage in five years. Last month, Mehdi Hosseini, an analyst with Friedman Billings Ramsey & Co. Inc., cut his forecast for TSMC due to lower-than-expected demand from foundry customers.

有问题又怎样？这种规模的公司永远不出问题，可能吗？intel的P1就出过问题，其他就不说了，结果又怎样？
我用过的NV的DD不多，N年前的帝盟的TNT 8M，小影霸的TNT2 32M，现在收藏了。05年的DFI LP NF4 UD到现在都好得很。
NV的DD不会死，只会慢慢消失。

大奶和二奶都是650i，年初帮别人配2块c68，3年前朋友的NF4一直OC至今

芯片组除了i就是n，另外的全是渣

2160+650i+4850+神条=爽翻了

我也帮很多人配了XFX 4MOS版650I，我自己也是这块，使用效果都很好，也有好几个月了，没一块有问题的，还都很能超

只能说我RP大爆发了，今天给JD电话，请他们这次发板前先点一下，即使是旧的也无所谓，答曰不可试...

这篇报道里面没有提到650i。

我的帖子貌似是就前面网友所说的没有见NV芯片大面积故障说说自己的感受
对了，说到NF4，我有个朋友在本地一家维修公司，据他说，华硕的NF4主板芯片挂了的很多，他自己的也挂了，技嘉的NF4很多芯片虚焊，我另一个朋友的GA NF4就是芯片虚焊以后SATA接口失灵

INQ算什么鸟东西，随便放个P满世界转它的消息，真无聊:sleeping:

其实NV所有产品都有严重的缺陷....

还是AMD-ATI厚道啊...

都去买AMD-ATI产品吧...

让NV自生自灭...呵呵！

BumpGate Only 630, 7050, 7100 and 7150 changed for no reason

怎么翻译？只有630, 7050, 7100 and 7150 没问题？

我想，至少650I的故障率不低吧
第一次帮朋友买，影驰3MOS版，没问题
第二次自己买，XFX 4MOS版，正常使用一周就不亮了
第三次帮朋友买，J D特价333的XFX 4MOS版，才到手4个内存槽只有一个能用，开始是无法进系统 ...

我也帮很多人配了XFX 4MOS版650I，我自己也是这块，使用效果都很好，也有好几个月了，没一块有问题的，还都很能超

莫问我是谁

NF550+3500+,bt专用机+24小时网游挂机打钱，两年来貌似没出过问题{victory:]

INQ是不是活腻了想被关闭了？
