9800 GX2 died, resurrected!

375f and bake it max 8 minutes?
is that safe enough for capacitor? i mean for old capacitor thats not solid cap?

I have done it a few times, and every one has worked.......so far. one has to be pretty careful though. If your oven is not running temps correctly, and is going way to hot, it sure might ruin something. I also think that a capacitor reaches temps around that when storing energy anyhow. Maybe not quite that high, but I would imagine it would hit the 300F at any rate.

The way that I originally figured it, if a person has a piece of hardware that does not work, and does the baking trick and it does not work, what are you out? Nothing; pretty much. If it does work, then you have a piece of hardware that did not work, and now it does.

Keep in mind, you have to put it on a cookie sheet (or similar) and suspend the PCB in the air with the four balls of aluminum foil, or something similar. I think that the cookie sheet kind of absorbs a good portion of the heat. You will get a very distinctive metallic smell about 1 minute before it is time to pull it. As soon as the 8 minutes is up, shut the oven down and pull the product out immediately. Do not, I repeat, do not leave the product in the oven after the 8 minutes is up! This may allow the solder to melt and drip off of the intended PCB!

Usually when a video card, for example, begins to artifact and have odd things happening in games, it is due to very small little cracks in the solder joints of the resistors, diodes, or main socket. These little cracks cause loss of continuity between the item and what it is intended to have continuity with. When it is baked, is softens the solder enough to allow it to flow just enough to close these cracks, and hence fix the issue that the board was having.

Hope this helps.

Any idea if baking would also fix a GFX card that doesn't output any image? I know the backing is suppose to fix pattern problems but never seen anyone baking a completelly dead card.

i also baked my brother's 7600gt but had 2 change all capacitors(old type).... -8 or 9 pcs.... but the card start without any artifact so is a good solution

however i learn from the baking and next time i'll use a heat blower and shield the capacitors as i loose 2 much time with cap change

 

[heky]

I also baked an 8800GTS 320mb just last week. Works like a charm now. I say go for it, but dont exceed the baking time. Around 9 min tops, thats it, take it out, let it cool, plug it in, enjoy!

No, that's not the case. Capacitors only store and release charge, there is no power being consumed. Therefore, they do not produce heat.

In a real life situation, they will actually warm up, but that's mainly because of heat from the rest of the board. They will also warm very slightly themselves too by a few degrees, because no capacitor is perfect: a tiny leakage electrical current flows constantly between the electrodes and they have some electrical resistance.

The way that I originally figured it, if a person has a piece of hardware that does not work, and does the baking trick and it does not work, what are you out? Nothing; pretty much. If it does work, then you have a piece of hardware that did not work, and now it does.

Yes, quite!

Sorry, but i can never see myself putting a video card into my oven and baking it haha. I would just go to best buy and spend whatever money i have to on a new card if one of my cards died.

Hehe, sell the pastry dough to the bakers here on the forum

On the otherhand, I have an 8600 GTS that died a few years back...might dust it off and throw it in the oven.

I know what you mean. I wouldn't bother, either.

Heck, a dead card is a brilliant excuse to go get another, better one!

Sure, but why not bake-repair the old one and sell it for profit.

 

[LDNL]

Been busy and the computer is being used as a server for the time being so the baked-potato is going to be in the pantry just a bit longer. Definitely gonna do it as it's not like theres really anything to lose

Ohh cmon already please entertain us!

Hmmm... good point. By the time one has flogged it on eBay, received the positive feedback and it fails after a while, it will be too late for the hapless buyer.

 

[RejZoR]

Well if you get back just 50% of the used item value that's enough. The other side will also be happy and in general the card should work long enough so the buyer will most probably replace it with another one again...

that is very sad...

imagine you buying something off ebay and its knowingly sold defective

also paypal as 45 day when they can take back the cash

Well, flogging a card revived in the oven IS flogging something defective. One could declare that it was revived in this way, perhaps. However, this will have the effect of lowering the price substantially, or not selling it at all though.

A card like this could well last more than 45 days though, so it's a gamble that the seller can take. If it fails within 45, then simply refund the money and there's no harm done. Also, a private seller doesn't have the same obligations as a company, so if it's sold with no warranty, it can fail within 45 days and the seller isn't obliged to refund the money. It just has to not be DOA. Therefore, if it fails after just a week, it's legally acceptable and a refund is at the discretion of the seller and whether they are willing to accept negative feedback from the buyer if they don't refund.

Personally, I have an A1 reputation on eBay and only sell stuff that I know is good, as I don't want the potential comeback and hassle.

That is very correct. The 8800GTX that I revived is still going strong in a friend of mines system. He actually has two of them in the system. God, that had to of been every bit of two years ago now.

The card is not defective when baked in the owen. A brand new one gets through a simmilar procedure at the factory.
Also why would a baked card die within 45 days? It should be almost as good as new.

8800GTX... now there's a legendary card. I've got one used one bought cheaply, a used Ultra bought cheaply, plus a brand new Ultra made by BFG, also bought cheaply (£100 some time ago) from eBay.

What do I do with them? They're part of my graphics card collection and get pressed into service once in a while if I'm trying something out. I've got lots!

A two year fix with baking sounds excellent to me and would be considered as good as any commercial repair. Nice.

Baking is no way the same as the factory process and it damages components, due to the high and prolonged ambient heat.

The factory uses flow soldering, where all the components are placed on the board and the card is run over a "river" of molten solder for a few seconds. Check out "flow soldering" on Wikipedia for the fine details.

I'm not quite sure how they do the surface mount stuff though. Wikipedia to the rescue...

I read somewhere that for repairing purposes they use heat to reflow the solder. It is even stated in some Intel documents i read a while back.
But, yeah, offcourse it is not brand new after the process, but it shouldnt die in 45 days either.

Yeah, could well be, heky; I'm by no means an expert on this, lol.

BTW I think your anti Facebook avatar is awesome! Cracks me up every time.
