　恕我問個外行話，請問這是封測廠還是晶片商的問題，如果純粹是晶片商的問題，那 Nvidia 現在的股價再打個對折也不過份；如果是封測廠的問題，那搞不好事態還會更嚴重。]]>Jul 11th 2008 1:52AMhttp://chinese.engadget.com/2008/07/11/all-nvidia-8400m-8600m-chip-faulty/http://chinese.engadget.com/2008/07/11/all-nvidia-8400m-8600m-chip-faulty/
The inquirer has been carrying this story for a long time. My understanding is that the GPU and substrate bond (I assume they're using some sort of epoxy, or some sort of underflowed bonding material) was slightly off-spec. That means that it doesn't share the same coefficient of thermal expansion as the substrate, and the GPU.

Everyone knows that Heat-Cold-Heat stress shocking causes extreme wear on that bond, and it's apparently just a matter of time before the affected parts fail. It's a problem I work with every single day in the CCD fab I'm part of.a There was speculation for a while that Nvidia knew about this since the A1 and A2 revisions of the 8600 GPUs had different core voltages, which was rather curious.]]>Jul 11th 2008 1:54AMhttp://chinese.engadget.com/2008/07/11/all-nvidia-8400m-8600m-chip-faulty/http://chinese.engadget.com/2008/07/11/all-nvidia-8400m-8600m-chip-faulty/]]>Jul 11th 2008 2:27AMhttp://chinese.engadget.com/2008/07/11/all-nvidia-8400m-8600m-chip-faulty/http://chinese.engadget.com/2008/07/11/all-nvidia-8400m-8600m-chip-faulty/
　比較糟糕的情況是，如果肇事廠商不願意拿出「有誠意」的解決方案，而是採用更新 BIOS、驅動程式一類「拖命撐過保固期」的方法，那恐怕損失的不僅是提供給憤怒的消費者 RMA 的費用，還會連帶賠上自己多年來累積的商譽，更嚴重者，還會對目前市場上還在銷售的 G92 與 GTX200 系列都會造成負面影響，到時損失的恐怕就不只是當年該認列的一次性虧損，還要斷送消費者對其未來所有產品的信賴感。

　以上，都假設這則新聞是真的，但基於市場健康與良性競爭，實在衷心期盼這只是個不實的謠言。]]>Jul 11th 2008 4:43AMhttp://chinese.engadget.com/2008/07/11/all-nvidia-8400m-8600m-chip-faulty/http://chinese.engadget.com/2008/07/11/all-nvidia-8400m-8600m-chip-faulty/]]>Jul 11th 2008 1:59AMhttp://chinese.engadget.com/2008/07/11/all-nvidia-8400m-8600m-chip-faulty/http://chinese.engadget.com/2008/07/11/all-nvidia-8400m-8600m-chip-faulty/

還是靜待NV的解釋吧。

看來很大比例的使用者被N社看起來「相反」的核心代碼給弄胡塗了

話說回來，現在佔台灣裝機與品牌PC最大比例的應該還是G84/G86(絕非多數人想像的更高等級與更高c/p值的其他產品，這個不用市調，直接走一趟賣場推出的套裝產品就知)

這個消息得到證實的話，有良心/肯維護商譽的廠商應該全面停止使用有問題的這兩款GPU晶片才對。]]>Jul 11th 2008 3:45AMhttp://chinese.engadget.com/2008/07/11/all-nvidia-8400m-8600m-chip-faulty/http://chinese.engadget.com/2008/07/11/all-nvidia-8400m-8600m-chip-faulty/Jul 11th 2008 2:59AMhttp://chinese.engadget.com/2008/07/11/all-nvidia-8400m-8600m-chip-faulty/http://chinese.engadget.com/2008/07/11/all-nvidia-8400m-8600m-chip-faulty/就是一天重啟之後，就無限藍屏 LOOP (勉強說是先兆)
