Failed bakeing

Just baked my 8600m gt for 7 minutes at 195C. Afterwards i noticed that there was a piece of plastic left on the GPU that melted (Yes I am stupid for not removing it =((( ). You can see the plastic on the picture, the black square surrounding the nvidea square. It didnt melt entierly, just got some tiny bubbles on it and got a bit bent in the middle. What should I do now? Let it sit there? Remove it? If I remove it, do I need to replace it, and in that case with what? I have no idea what that part is called.

 

Rip it off and see if it works. That plastic doesn't do anything. It is just covering the rest of the GPU packaging.

 

You should be fine. I think that plastic is just there to keep the metal heatsink from touching exposed contacts and creating shorts. As long as none of the actual electronics are melted you should be fine. Just leave it as it is, put it back together, and see if it works.

 

ROFL.... wait what did you try to accomplish by baking it - make a silicon cake?

 

Bringing the GPU back to life of course.

 

Thanks for the answers. After examining it a bit closer, it looks like applying thermal paste might end with the paste getting in contact with the circuits. Dont know if that is a problem, but besides that I think it will be fine. I dont have any thermal paste at home, so I'll buy some tomorrow. If someone have any thoughts on this matter before that it will be much appreciated, otherwise I will give you an update later on how it went =)

 

The 8600 series GPUs had the same cheap solder problem that caused the RROD on the XBOX360. By baking them you might get lucky and cause the solder to melt just enough to reconnect the GPU to the motherboard. I think it has something like a 70% success rate (just guessing). It's not perfect, but it's better than nothing.

BTW OP, there's an ongoing lawsuit against Nvidia regarding this issue, they're supposed to have to replace your laptop, even if it's out of warranty. There's a few threads about it on these forums if you search a round a little.

 

It depends on the type of thermal paste. Most newer pastes are non-conductive, so you shouldn't have a problem.

 

Interesting! Sooo... how come the transistors don't get toasted at temps way above the temperature the laptop would shut down? I already gave my old crappy m1330 with the same GPU away. If I can swap it for another Dell computer, I'll bring it back to US.

 

I'm with others who think it's fine. That plastic just looks like the protective cover on the GPU die and not actually part of it. Try removing it, use a non-conductive thermal grease like OCZ Extreme Freeze, MX-3/MX-4 or ICD7. And then see if it works before throwing it away.

 

Transistors (and silicon chips and pretty much anything on a MB) can take much more heat than the 110c thermal shutdown limit, just not for extended times. It's the plastic case you have to worry about since it can actually start to melt, or the battery might explode.

 

My 8700m had a wire I couldn't remove from it, so I wrapped in tinfoil and baked it... Got the idea from a turkey recipe actually. XD It said to wrap the exposed leg bones to prevent charring, so I did the same. 8700m is back to life and back in my Toshiba X200.

 

Good news!
I let the plastic sit where it was, applied some thermal paste and reassembled the laptop. Right now it is sitting next to me, with it's big screen shining like never before!
Thanks for the help guys, really appreciate it!

 

Glad to hear it!

 

Well, putting the battery in the oven sounds extremely stupid. I'd guess people actually take the motherboard out before doing this feat.

 

He did, look at the pic. I don't think that anyone is seriously stupid enough to bake the entire laptop.
