Well, a little back story first :)
After having received a non working card from a forum member here(no names to be mentioned) eVGA and all their greatness was kind enough to send me a replacement 660Ti to replace the dead 570, even though the 570 was no longer in warranty period as I was the 3rd+ owner of the card. The replacement 660Ti worked great for a few months until last week, my girlfriend started telling me her computer kept freezing and having lines through the screen. The artifacts & lock-ups became more and more frequent, to the point even during post screens artifacting was abundant. it was time to throw in the towel. I called eVGA tech support, and being as the 30 day window of warranty was up, I decided it was time for the last resort.......oven bake time! I stripped the card down, per-heated the toaster oven to about 390 degrees, threw the card in for about 9 Minutes, then let it cool for about 30min. After re-assembling the card I tossed it in one of my rigs and low and behold, no more artifacts! I then proceeded to fire up Crysis 2 for good measure & put a good load on it. I let the card idle in game for about 30min, no crashes or other issues. It's now been running in my media computer for the last 20 hours or so, no issues.
So far my video card baking record, since my first time doing it to a 6800 Ultra is 5/6! I am eager to see how long this will last! I have friend, who I baked his 9800GT about 4-5 years ago, and to this day, it's still being used in his work computer! I am anxious to here others experiences with baking their cards & see if they have had good luck as-well! Or here any horror stories of doing so!

I bought a bad GTX 295 off of Craigslist for 15$ and baked it, then used to to play BF3 for about a week, then sold it for 75$. As far as I know the guy I sold it to is still using it to this day.

[Edit]: At Tweaked, I used a blanket, wrapped the PS3 up in it and made a whole just big enough for a hair dryer, after about 45 mins I took it out and left it. He entire case warped from the heat, but it worked. My cousin is still using that PS3 and I fixed it in January I believe.

That is awesome about the 295! I know many say it's just a temporary fix, but this for sure shows, it can be permanent as-well! And I am surprised your blanket didn't catch fire doing that to the PS3 lol! That is an awesome fix! I've never personally heard of that fix before!

Yeah, I've baked a 8800GTS about 4 years ago. Still works.

 If I remember right that was the only way to reset an Xbox to default was excessive heating. Er or was that PS3? I must be slipping with age.

I've baked a couple 9800GTX+'s, a 470, a 570, several motherboards, and a PS3. The PS3 and 470 have been the only things that didn't work again (They were already broken anyways). Everything else is still completely functional to this day. I also enjoy people being extremely confused when I put my computer parts in the oven.

Both of them had issues that could be fixed by baking.

You should have seen the look on my moms face when I was preheating the oven and she asked "What are you doing?", and I responded "Why I'm going to make a GTX 295 Pie!". She knew exactly what I meant, and then proceeded to tell me that it will 'never work' and that I am "wasting my time and their money heating up the over". When it did work, the look on her face was priceless.

Well glad to see more and more experiences at least. Now been 2 weeks, card is still running strong! this weekend card logged a good 16hrs of Elder Scrolls Online & Sims 3(not very GPU intensive but still). Hoping this card can hold on for another year or so!
