I've read about the oven baking a video card back to life before. When I first read about this, I though it was a joke post, but surprisingly it was actually serious and it actually works for many people.

Can someone shed some light on as to why this works?? If really high temperatures and revive a dead GPU, then does putting it in the freezer also have the same effect?

Putting it in the freezer will not produce the desired affect, but i can confirm that i have successfully recovered my files from a corrupted HDD by putting it in the freezer. In fact i forgot i put it in there till my wife was complaining about it a week later. Loaded it up and it has worked fine ever since.  (Obviously i don't use it for anything important now.)

It must be done carefully, a certain way. What it does it "reflow" the parts on the card - essentially melting all the solder and possibly making broken connections good again. That is actually how the cards are assembled at the factory, they pick and place all the components on the board, and then put the thing into a reflow oven to melt it all together.

I have two cards which are somehow damaged. They can't be used for gaming but they mine perfectly. One has been stable for 2 weeks now and the other 11 days. When used for gaming the screen starts to blink. Dunno what the problem is. Paid only 25% of the real value.

Probably bad RAM.

Mining doesn't use the RAM much at all, usually only part of the first chip.  If the bad RAM is a different chip than the first one it should theoretically function perfectly for mining.

Can always put them in the oven and do some baking, works surprisingly often.

in my experience (2 duff GPUs) neither of them were recognised in any miner

I've seen alot of damaged GPUs on ebay that sell for a fraction of the cost of a working one. I was wondering if they can still be used to mine. Sometimes the listing states the GPU won't output video correctly for instance, but the computational part (I'm assuming) is still viable. I know its risky because you dont know exactly what the problem is and every one is different, but could one buy up some really cheap GPUs this way?
