All Nvidia G84 and G86 chips faulty?

By on July 10, 2008, 5:53 PM
Nvidia’s stock took quite a beating last week after the company announced a financial forecast cut short due to slowing sales and a hefty payout to cover the expected cost of “significant quantities” of faulty notebook GPU’s and mobile and communications processors. While the company remained tightlipped as to what product lines were affected, a recent report by The Inquirer suggests that every single G84 and G86 GPU in both mobile and desktop cards is affected.

Nvidia’s official claim is that it was only a batch of end-of-life parts that were affected because of a faulty bonding process. But according to The Inquirer’s sources, both the G84 and G86 GPUs share the same ASIC across the board – which is the source of the heat-related issues – and there’s “about zero chance” that Nvidia would change the assembly process or material set for a single batch.

Furthermore the graphics firm claims that only HP products are affected, but apparently Dell and Asus PCs with the affected chipsets are also failing. This all remains unconfirmed for now, but hopefully Nvidia will step up and clarify this whole situation to its customers.

My card has a heat problem, play any intense game for more than a few minutes and the whole screen goes mushy red. Sent it back for replacement, still no change.

my 8800gt runs very hot too- all you need to do is put it to 100% fan speed in the nvidia control panel when you play games - a little anoying and quite noisey but when you play a game you don't hear it and it cools it alot - from like 85 - 60ish degrees. hope this helps.

My 8600GT never had a heat problem, apparently, it was electrically defective and refused to work when the correct drivers were installed.

I've worked on two different HP laptops that have ended up having this issue in the last 2 months. One had an 8400 that would artifact and bluescreen after the correct drivers were installed and another that I just sent in that would do the same thing but has an 8600 chip. Seems like a similar issue to what happens to the x360 with its ATI chip and the RROD, the GPU separates from the board and loses contact due to extreme temp changes over time.
