official words from Nvida regarding 8x series?

Hey everyone, I have a benq s41 with a 8600m gs and it fried once already. had to pay for a repair 2 months ago since it was out of warranty. I was wondering if ALL 8600m gs are defective, or just a certain bulk that was made before a certain date was defective. I have a feeling this new card will fry soon or later. If the laptop goes out of warranty, would I still be responsible for the breakdown? Or could I explain the defective theory to Benq for a free repair? I believe Nvdia only released words about defective dells..

any help is appreciated

 

The entire 8xxx family tends to overheat...since it' made in 65 nm process, even without OC these GPU's just work damn hot

The 9xxx series is basicly the 8xxx series with 1 major improvement - less heat due to 55 nm process

You just have to monitor your temps, and don't overclock your 8600m, ever

 

what temperature would you say is an acceptable temp? My idle temp is ~61 and working temp is ~73 degrees

oh btw its a 14.1 inch laptop

 

Just as low or as constant as possible. I think temps below 65C are good.

Actually my 9600M GT is 65nm, and I think the 8x00 is 80nm, at least some of them...

 

You may want to consider a cooling pad/rack to keep the GPU temperatures down. The other responders are correct in that the nVidia mobile GPU failures are due to insufficient heat dissipation around the GPU. I bought a used Dell XPS M1330 notebook PC with a nVidia GeForce 8400M GS GPU 7 months ago. The GPU failed 2 months ago (PC was 17 months old at that time), but fortunately Dell replaced it and the motherboard (GPU is integrated) under its extended warranty for nVidia GPU-related problems. Immediately afterwards, I installed Everest Ultimate to monitor its temperature and bought a Titan Aluminum Notebook Cooling Pad Model TTC-G4TZ from Newegg for $38 + shipping. I use the cooling pad constantly and fortunately it's pretty quiet. I've compared the GPU temp with and without the cooling pad in idle (i.e., writing email or net surfing), watching video, and playing a flight simulator combat game. The cooling pad appears to lower the nVidia GPU temperature by 6-12 Celsius (C), depending on load, and maximum GPU temp has been 78C.

As you may know, a wide array of notebook PC cooling pads are available (I counted over 20 on Newegg alone). I bought my cooling pad based on its design (4 fans, adjustable to fit notebook PCs between 12" and 17", metal surface) and the notably positive user reviews on NewEgg. My cooling pad is no longer available with Newegg, but it is still listed on the Titan website ( www.titan-cd.com), suggesting it may still available elsewhere. Of course, I cannot vouch for the performance of the many other available cooling pads or even the Titan with your notebook PC, but based on my experience, a cooling pad may be a worthwhile investment. I've also noticed that with my PC and cooling pad, the positioning of the fans relative to the vents affects the cooling performance greatly, by about 4-6C.

 

While the spirit of this is true, the problem with the 8600/8400's was in the manufacturing process and the soldier bumps they used. Although nvidia never did come clean about this issue.

I agree though, if you have a 8600 don't overclock it unless you're cool with replacing it.

 

It was never made entirely clear, but the rumors on the web are that pretty much all of them are defective. That said, the issue is not that the card overheats -- if your card is overheating, something is wrong with your cooling. The problem is that changes in temperature (e.g. those that naturally occur when the computer transitions from off or asleep to on or when you start playing a game) eventually cause the solder to crack and then the card stops working. A cooler isn't going to help you much unless the card is actually overheating.

If you have no warranty, you're pretty much out of luck because neither Nvidia nor the manufacturers officially admitted to this or modified their warranties to reflect it.

 

A very good reason to not buy Nvidia next time.

ATI might of course have done the same. It's just that the only way for consumers to make a point is to spend money on something else.

 

The G80 (desktop 8800GTX, GTS 320/640), G84 (8600GT/S, 8700M, 8600M, 8400M........ 9650M GT (or GS?), 9500M GS ) and G86 (8500GT, 8400,8300....) are 80nm. Those are the ones with the problem. The rest of the 9-series + 8800Ms are 65nm (G92 and G94, not sure if G94 was ported to mobile though, I think they just used laser-crippled G92. The G92b is 55nm (9800GTX+), The first version of the GT200 core was 65nm, now it's 55. Dunno about the mobile one.

And yeah, although it's true the G84m runs very hot, it's not the cause of them breaking. Mine runs 80idle and 96load. Been like this for 2 years.

 

I've been using the antec notebook cooler and it does lower my temp by 3-5 degrees. It works by sucking air away from the laptop bottom. I wonder if a cooler that BLOWS air into the laptop would be more efficient since the laptop bottom is where air goes into the laptop integrated fan.

 

9650m are 55nm

 

Dell has extended its warranty for problems related to several models of mobile nVidia GPUs installed in its notebook PCs (see URL below). As I related earlier, my Dell XPS M1330 notebook PC, which I bought used, had a failure of its nVidia GPU 5 months (17 months after initial manufacture) after I purchased it. The GPU failure occurred in late May 2009 and the PC was repaired by mid-June 2009. The original warranty had expired, but Dell repaired my PC under the extended warranty. Admittedly this extended warranty is not highly publicized--I first became aware of it from a respondent on a Dell forum when trying to determine the exact problem with my PC--and I had to jump through a proverbial hoop or two to activate the extended warranty.

As Althernai points out, nVidia is not officially admitting that there is a problem with their notebook GPUs and the semi-secretive nature of the extended Dell warranty suggests Dell is not either, although Dell seems to doing more to address the nVidia issue than other notebook PC manufacturers.

G94 (desktop 9600GT) was ported in the form of the 9800M GS, and I believe the 9700M GT and GTS were the crippled versions, *however* all mobile GPUs in the 9700M series and up to the 9800M GTX are listed on Wikipedia with the funky codname of "NB9E GS/GTS/GT1/GT2, etc" so they could all be just different versions of crippling, though it would be stupid to manufacture that many in such a manner due to electricity leakage of which case there a high degree of TDP variance when you go from the bottom to the top, so I think they are mostly dedicated chips, in which case, yes the G94M is a mobile verson of the desktop G94, the 9600GT.

 

Hate to say it, but I had an HP with a 7600go and it fried. So its not just the 8 series. Of course HP will not fix, out of warranty, unless you have an AMD cpu.......................wth difference does it make which cpu you have , its the same 7600 thats going bad .

Precisely why I now own a Sager !

Will never buy brand-name again !

 

2006 era HPs were known to die early because my died only 1.6 years after I bought it. The GPUs had bad saudering to the motherboard which eventually came apart after an extended period of time IIRC, though my Wifi adapter was to die before the GPU, and my GPU not to long afterwards. I'm sure my OCing antics only contributed to the issue

I miss that computer though, interesting set up it had. One of those machines that was fun to tweak games on simply because you had to tweak em to run good with the Geforce 7200 and it's 64 MB of dedicated VRAM + 192 MB of shared........

 

There's the 9650M GS and the 9650M GT. The GS is a rebranded 8700M GT and the GT a 55nm G96b. The 9800M GTS and M GT's refresh (1GB edition) are 55nm G94b. First editions were rebranded 8800Ms (G92)

@Mobius: Yeah that's because of refreshes. They were first released as G92/G94 but then refreshed with the new GT200 core. That's what I just read. But I wouldn't trust wikipedia for the mobile 9 series, they listed all the GF8 refresh into GF9 (9500M GS and the likes....) as 65nm G96. That is so wrong. Even cpu-z says 80nm G84
