Baked my go 7800GTX

My go 7800GTX has been dead for over 2 years now in my XPS M170. Now I thought I would try the "bake in oven" technique that a lot of people has done. Guess what the GPU is alive again. According to Dell diagnostics the memory failed. But baking it in the oven around 195+ degree celsius for 7 minutes solved the problem.

My old XPS M170 is up and running again, can´t be more happy since I know how overpriced these GPU´s are on Ebay.

Nice to hear that the "method" has been working well for many brands/models.

Share with us your personal "baking" steps?

cheers ...

Yes here is how I did:

1. Removed the heatsink + two lilac pads on the GPU.

2. Heated up the oven to around 195-200 degrees celsius.

3. Prepared a form with tin foil and made four tin foil bases that the GPU would rest on, so it didn´t touch the base form directly.

4. Placed the GPU upside down and had it in the oven 7 minutes.

5. Let the GPU cool down about 15 minutes depending how cold you have your room of if you are outside of course.

6. That´s it, it worked. I hope more people fixes their GPU this way.

by heating up the card, you are re-flowing the solder on the board, which in some cases corrects a bad solder joint from the heat the card has been subjected to.

If you were to look at a bad card under a microscope you would most likley find that some of the pins on the surface mount chips have lifted, or just a plain old bad solder joint.

This kind of fault is very common when the board is subjected to high heat over time. it is only a matter of time

My card lasted a couple months after this fix, but died once more, not to be revived again (I tried a couple times). Good thing I got a warranty on it.

As has been said: it is still worthwhile, because you've got nothing to lose if the card dies.

Though this method failed the second time I tried it on my vid card, I aimed my heat gun at the metal box holding the headphone jack for a few minutes of 400-degree heat and it revived the right channel, probably another reflowing solution.

The heat-gun is probably a better precision tool for this successful 1/2 baked solution.

Yeah, I used a heatgun recently on my defective card. We applied it at about 350 C around the gpu for a few minutes. It held on only 2 days because I really enforced it with 3dmark 06 and watched HD movies. My second try was at 400 C and a couple of minutes longer. We also applied a special liquid around gpu, we tried it to infiltrate through BGA. Now it is working again. Don't know how long will it last though.
