I was given a Fry's system with a Foxconn 8800 GTX/768 along with Intel Q6600 CPU.

The system wouldn't start with the Foxconn card so I put in my EVGA GTX560ti 448 and it boots fine.

Is it possible to revive the 8800 via the baking method? I took off the the thermal pads before reading the long bake thread; so I have to get some more, if necessary.

Can I just test the card without putting the fan, paste, and thermal pads by starting the system and quickly turning it off after POST? Or, will the card overheat that quickly? I'd rather not buy thermal pads if I don't need to; I already have thermal paste though.

Also, what's a good NVIDIA (AMD) graphics card to go with the Intel Q6600 if I can't get the 8800GTX to work? (I have an extra EVGA 9800GT I'll use unless there's a better option; is the 560ti 448 too much?"

It should be OK with just past on the core for just test fireing it up as I don't recall seeing any cards with pads on the core it self, which is the hottest part and would likely catch fire without at least the cooler attached and fans turned on. Don't try to test it without the cooler on in my opinion. Now you could also probably use cheap double stick tape as pads just for limited testing as long as the cooler makes good contact with the core.the ram an vrms probably be OK for a short time with something like that.

The 560 be OK if you got one cheap.....nothing wrong with that choice depending on the price of course

And yes its completely possible to fix with bake method....just no Guaranty's
 
Thanks. No, I have an extra 9800gt and 560ti 448. Wasn't sure if the 448 would be bottleneck the Q6600.

What's the consensus for the baking?

GPU side up
385 F for 10 minutes? Ive seen anywhere from 350 to 400.
 
I wasn't bottlenecking a GTX480 with my Q9550. I'd say the 560ti 448 would be fine in that setup.

I believe i did gpu side up last nvidia 280 i did....think i did about 375 for temp but i kept a close eye on how it looked and smelled the hole time with the light on and using a bright light to peak in.....figured i had nothing to loose but it worked anyway...now it just sits in my backup parts box:rolleyes:
 
380, 7 min

one of those laser thermometers is really handy as oven thermostats are not very accurate

elevate the card on little cubes of crushed up tin foil
 
That 560 is a perfect match for a q6600. Slap a decent cooler on the CPU and run it at 3.0-3.2 ghz and your set.
 
Yeah, there's no reason to step back to an 8800. So many games are GPU bound these days.
 
You can get a GTX260 and even a 460 for under $30 shipped if you advertise here that you want to buy one if you want to keep your 560, but I bet with an overclock on the C2Q it will run well.
 
Baking video cards don't fix them, it just ruins your oven from toxic chemicals burning off the card and sticking to every surface inside the oven. The fumes also vent into your house and those chemicals are things you should not be breathing in. The gift keeps on giving, every bit of food you cook in there from then on is going to be contaminated with solder flux, heavy metals, etc.

Conventional home ovens cannot get hot enough to remelt solder, at best it causes the fractured BGA joints to weakly stick together again, giving the illusion the card is fixed when it isn't. I think the hottest I've ever seen an oven have a dial for was 550F. ROHS solder used on electronics from 2006ish onwards melts at 700-750F and even regular 60/40 melts around 650F.

The best solution if you don't have a BGA rework station is to use a heat gun (no, not a hair dryer) so you can direct the heat where it needs to go (the back of the GPU) and not to other places like capacitor banks which will boil in their cans if you get them hot in an oven.

why dont you go post your super intelligence in this thread http://hardforum.com/showthread.php?t=1421792 and tell the hundreds of people posting successful results that they just imagined fixing there dead video cards. I am one of the same people who have fixed a card following the same procedure outlined in this thread.

And you do realize the card hes trying to fix dates back to about 2006 anyway right? So even if the info you posted is correct, your contradicting yourself because hes not trying to fix a brand new 970 or titan x. If that were the case then i might be able to agree, but for goodness sake its a card that predates one that i have fixed you claim is unfixable, and i never had a problem with it till i upgraded....i just retired it do to needing something with more vram for the most part.
Just about everyone here will agree your posting nonsense
 
Not to mention that many of us here are electronics hobbyists, the solder fumes I have been exposed to when baking the tens of boards I have fixed is a tiny fraction of what comes off my iron.

Our physical civilization is made almost entirely of carcinogens of one sort or another, I for one, am not going to live in a bubble.

I baked my bro's 9800gtx cause it was artifacting. I forgot the temp...the first time maybe was 350F. It ran benchies for a minute or two then artifacts came back. I put it back in the oven at a higher temp, maybe 375 or so for longer than suggested. Card worked like it was new after the second bake

No fumes or smoke or anything rose from the card.

I have a heatgun though, I may look into that if the need arises.

Why don't you raise your intelligence and learn metallurgy. If an alloy melts at 700F and you only heat it to 350F, common sense tells you that the alloy isn't going to melt. But like anything, metal expands when it gets hot and it tends to become sticky. Your "fix" is nothing more than a broken BGA joint expanding slightly and sticking together VERY weakly.

All of the info I posted was 100% correct. It's hazardous to your health to cook electronic components. Why do you think that people that work in fab plants have to take so many precautions?

And where am I contradicting myself? I never said anything about the age of the card, that's extra crap you added. Whether you bake a PCB made in 2001 or 2015, the results are going to be the same.

Stop attacking straw men, you're making a fool of yourself.

then why do components start falling off the bottom of the board if you leave them in too long?

You, sir, are incorrect. Many, many thousands of people have reworked boards in the oven.

I suggest you stop digging now.

Do you know anything about how solder works? You're asking inane questions that people that know what they're doing already know the answer to.

The components are falling off because the solder is ejecting them off. Remember the part about how metal expands when it gets hot? SMD components are placed in a pool of solder where the solder hardens to hold the legs of the part like a vice. The top of the legs are usually not covered so they "fall" out if the solder base expands too much.

Solder also becomes brittle when heated due to oxidation and decomposition if you don't add agents like flux to prevent this. An oven obviously doesn't do this so the solder fails.

If you quickly heated the solder pads to the correct solder melting temperature, the lighter components wouldn't fall off because the liquid solder would stick to the SMD parts. The heavier components like big inductors, electrolytic caps and the like could fall off if you jarred the PCB.

More like thousands of people are incorrect and chose to remain ignorant. Like those people that thinking that wrapping a towel around an xbox is a permanent correct fix for an RRoD.
 
dude, I have seen the molten solder with my own eyes

I have jiggled the pools

but whatever

this is your own quote

if the date meant nothing then why did you keep bringing it up? These are your own words

Regardless according to you everyone who fixed there electronics in the bake thread I posted is full of shit and delusional right? Like I said go argue with them that none of there shit really works.....cause were tired of hearing it

Again, where did I contradict myself? before 2006ish, manufacturers used leaded solder which still can't be melted in a cooking oven. Hence the saying the age of the card doesn't matter.

Working card =! fixed card.

That's like saying overfilling your engine with oil to make it stop knocking is fixing the problem. Baking a card is a triple whammy; Toxic substances, doesn't fix the problem and damages everything on the card.

If you're tired of hearing it, you should leave the thread because this thread is about baking a card.
 
Well, I just cooked my 8800GTX at 385 for 10minutes. Used rocks as a support.

Opened a bottle of Chianti along with some fava beans. Attached the fan. Inserted it in the slot. Pressed that power button.

And...it worked! Thanks to all who helped Now just need to get some thermal pads.

How long do cards typically last after baking? I realize it may not last long but wanted to try it with a totally dead card.
The mobo is ECS nForce 680i. So far so good. Now I have a working extra system.

(side note: didn't notice any excessive fumes; not planning on starting a video card baking service)

Also, don't appreciate GiGaBiTe telling others to leave the thread.

great news...glad it worked for you;) length of time varies from 1 week to years...i used mine about a year and a half with no issues and just retired it since i bought a new card...but if my new one needed rma im sure my backup still works as good as day one

Bottom line enjoy your now working card:)

What does then? :s
If it didn't work -> baked -> working. Wouldn't that be called a fix?
Plenty of people have had long term working devices after baking.
Logan from Tek has had a baked Korean monitor sitting in the background of videos for a couple of years now.

What do you want?
 
it's safe to run it for few seconds without a fan..enough to see if the pc posts or not. Few seconds only.
 
This brings back memories - the first card I did this to was an 8800GTS back in 2009. Worked like a charm.
