GPU baking advice

Hey guys,

unfortunately my 680M bit the dust.

While I am looking for a replacement, could you give me some brief advice or a good guide on how to bake the card in a last attempt to possibly get it to work for some more time? I'd love to use the card until the next generation of mobile GPU's are released... was actually hoping my X7200 to last until the desktop 1080 fits a Clevo.

Best regards

 

I believe this will be of help to you.

 

Thanks @Plur !
So after I bake the GPU, I can not use the oven for baking food again? Is that true?

 

I've never had to try and bake any electronics. However it doesn't seem farfetched that it be true that various gasses are released and could potentially be toxic.

 

When I baked my 8800GTX I had to do it 3 times. First, it didn't work, second time it died within weeks and third time it did the trick. I remember using 4 foil balls on each corner and wrapping it into foil. After baking I let it cool down before moving it around.

 

Nice, will try that. Did you bake it in your household oven (and still use it for baking food)?

 

Sadly I did. After seeing Linus video I would considering buying cheap oven.

 

Maybe find a small one like a pizza oven at a garage sale?

Hope it goes well and can extend the life of your card just a little while longer for you. Baking isn't a long term solution for a fix.

 

Thanks pat, I will keep my eyes open and this thread updated how it went. I'm aware baking (at best) prolongs the life for only a short period of time. I merely hoped to bridge the time until Clevo features a 1080 (non M) card, for then I will look to buy myself a new machine.

 

You do have to be very careful, just a little over for a lenth of time and it's toast.

 

LOL! that was puntastic.

 

PCB re-flowing in the toaster is probably a bad idea

 

Ha I don't want to jinx it, but I reflowed the soldering of the core using a heatgun of a friend and it - so far - worked!! I just warmed the PCB evenly for about 2 minutes, then concentrated the airflow on the core while shortening the distance of the heatgun to the PCB. After 4 or 5 minutes I changed the heatgun from 350° to 550°C and intensively heated the core for 40 seconds.

I can confirm that there was quite a bit of smoke and fume, so I'm glad I didn't ruin my oven with it.

Since then I used the notebook for 2 hours, and other than the screen turning on a bit late (5-10 secs after pressing the power button) flawlessly. I did not try intensive 3D applications yet, just some HD youtube videos.

Thanks for your advice guys!

 

A heatgun can be a more precise method, solder will always produce some fumes but if they were truly dangerous you would see far more warnings on the cards.

 

No chance for 1080 by x7200
But gtx 680m is the best what you can have.

Hahaha, THAT's for sure. I didn't mean that the 1080 should fit my good old x7200, but any newly released Clevo model (and I was referring to the desktop 1080, like the 980 non "M" fits notebooks currently).

 

That's great that you were able to revive it. Just curious, is there any noticeable performance difference?

 

I just went ahead and did a 3dmark11 run, and the results are perfectly normal. http://www.3dmark.com/3dm11/11391553

I'm so releaved! I just hope it will last a few months so I can wait out mobile Pascal and buy a new notebook when the card finally dies completely.

 

That would be very odd considering that electronics don't degrade like an engine. Linus did a fun video on it:

 

I just wasn't sure if the heat would affect of the graphics card, aside from fixing it back in to place. It was just something I hadn't really checked in to. Thanks for that update there as well.

I saw that video was available, but hadn't sat down to watch it as of yet.

 

Now if you were look at analogue circuitry it would be very different

 

Guys I hate to bother you again, but I have a brief question:

What is more likely to work in my x7200, a Dell HD 6970m or Dell Nvidia K5000M?

I ofc flashed the vbios of my (RIP) 680M before, and could probably do it blind. Based on some threads here, Dell cards did actually work plug&play in Clevo notebooks in some reported cases.

I'm asking because my 680m seems to be failing again, after not even a week of coming back to life.

 

I believe the quadro cards do tend to work.

 

Try baking it again
It took me 3 attempts to make it work. I searched around and used different methods each time. It was long time ago but if I remember correctly, last try I baked it little bit longer.

 

Baking isn't a permanent fix. I'm not surprised that it only lasted a week, this is a short period fix that has been perpetuated by the internet since it works sometimes. An """""improved""""" baking method would be to get liquid flux beneath the BGA chip before baking to allow the flux to help the solder reflow. Better would be reballing. Both these would only work if the defect is in fact the solder balls. Bottom line: 95% of the time reflowing/reballing is BS.
