You'd probably seen this somewhere else, and this isn't mine. Full credit goes to antipesto93 from OCForums, and Haste266 for the brilliant how-to.

I had a dying 7800GT on my hands, whenever it ran 3D games it started to chug and eventually BSOD. A week later, the card started having artifacts even on Windows, and a day after that it wouldn't even boot. So I heard of a crazy method where you literally place your graphic card in an oven, let 'em bake and plug it back in. This was obviously met with furore, and no one thought it would actually work. Nothing to lose, I popped it into my mom's baker.

It now works. Hard to believe, but it works.

Apparently the methodology is similar on how it is usually done at factories - the card is heated up to allow the solder contacting with the ICs on the board to melt and reform the bond that was weak in the first place (which might be the cause of artifacts/problems). A short time is only required, with a maximum of 8 minutes, and at a temperature of 200C.

So what do you need, and how is it done?

You'll need an oven capable of going up to 200C. Microwave ovens don't count. Some aluminium foil, a cookie tray, and thermal goop of your choice as well too.

First thing to do is to strip all bolts, nuts, screws, whatever fasteners you can find off the board. This includes heatsinks. Stickers may remain. Strip them off till you're left with the bare PCB. Be sure to remove all thermal tape (you might want to keep that for the after-baking session) and thermal grease. Cut up some aluminium foil about the size of your card, and place it on the tray. Then, ball up some of the remaining foil to use them as stands, as you don't want the card to get in contact with the foil below it. Be sure that stands are positioned at a connector/PCB, and the card should be facing down. DO NOT place any stands on any ICs/capacitors, most of them are probably surface mounted and would probably shift from its position during the cookoff, screwing your chance of revival even further.


The card, all cleaned and gutted


The oven awaits!

Finally when it's ready, preheat your oven to 200C. If your oven is fan assisted, switch it off. Once hot, put it into the fiery pits of hell oven and watch it burn for a good 8 minutes. Some even did it for 10. Just don't overdo it, and let the heat soak.


I did this at 8AM in the morning. Luv the smell of flux and heavy metals in the mornin'.


Xtra Crispy

After the toast, carefully remove the tray and place it to cool. If you can smell flux (the same smell in your Kemahiran Hidup cheapo projects), you're probably good to go. Air the place as well, you don't want to breathe in the bad stuff do we? Once cool, reapply the thermal tape and paste, reassemble back the card, plug it back in, say a little prayer (if you're an atheist, grab a beer. If you can't drink Ribena would do) then turn it on.

Hope it works for you. Mine did.

that's coollll

1 question..
dont the caps get too hot in the oven..

because some caps do have temperature tolerance right..

afraid the caps will blow out.

1 question...microwave can use instead of oven?

metal stuffs in microwave oven is a big nono if i remember correctly..

I had a rosak ti4200...boot up with artifacts all over the screen.

but no oven.

yeah how can the caps survive 200C of heat?

On the other hand,careful of residue of gpu left in oven? u dont want 7800 muffin to go into ur throat haha.

video connector made of plastic if im not mistake. not melt?

do u know how the microwave work?
any partical that absorb the energy will generate the heat..
and metal only reflect those wave..
thats y metal is big no no in the microwave oven..
unless u got convection/grill+microwave oven 2/3 in 1

mayb can only b applied to the graphic card w/ solid caps only
btw, the aim is to melt the solder n reform the bond
IINM what ever temp that melt the solder will melt the plastic part s well

http://wiki.answers.com/Q/How_hot_does_a_b...ghter_flame_get

i accidentally burned a DVI connector once with a cricket. it survived without even melting, so there you go.

i heard 3 case this year, all is successful,

but never heard/see failed case..

It a good info sharing here,problem GC can be revived with just a 10mins in an oven.

omg i've lost my old GC , shouldnt have throw them away .

I think the plastic stuff was put on after the heating process in the factory?

but someone had done it with success story.too bad I dun have an oven...

Interesting... any prerequisites to the GC? Must it have certain type of cap/chips, or a certain layout? Soudns too good to be true

Maybe a screenshot of pc running the after processed gpu?

Solid type caps should be able to last the cookout better than the standard aluminium ones. Some even went to the extent of wrapping those caps with extra foil to protect them, but for me as long you aren't leaving the card there for a very long time it should be fine. So far, no reports of exploding caps to my knowledge.

Why bother about the caps if the card is dead to begin with?

About the residue, yeah there might be a health risk in that, I don't want flux on my choco cake either, it'll make it taste funny. Most stuff are RoHS compliant by now, but I wiped the oven interior just to make sure.

I was skeptical of that too, but nothing got warped/melted at all. Probably the quality is much better than the average plastic bag lol.

7800GT so far passed 5 hours of FurMark, damn now I know why people want your faulty GCs...

wow...cool method dude...

Great...
I shouldn't throw away my dead old GC...

this method only work if the problem with your GC is with bad IC connections.... if the problem is IC related, then heat will make it worst.

1) The card is already dead. I doubt there's nothing worse than a dead card.

2) The problem lies with the soldering material. You see, those RoHs certified solders used on the GPU (the chip) are not as good as the lead-based ones. A reheating makes them reflux and puts the connection back to its proper place.

3) This method will also fix super-artifacting cards (i.e. half the screen is full of artifact while the other half remains clean).

4) Putting it into an oven(not microwave oven) is how the industry solders the cards properly, so it's perfectly safe(baking the card for 30 minutes is still NOT OKAY).

5) Those who got this problem are usually unlucky. It's not supposed to happen.

usually,all semiconductor do this on pcb to heating using furnace.concept is same as oven but run in rail long machine using timer or manual

y not use heat gun
a lot easier though!

this method can fix this problem ?

I would like to ask, the GC is made of dual layer pcb, won the bottom solder parts melt and drip? If it does, the component will lost contact with the pcb right?

@K.E.

what card is that?

Its time to cook it to know.Maybe ts can cook it for u haha.

@ K.E
how old ur GC?

Putting it in the oven instead of a heat gun warms up the card evenly rather than a certain area.

If it's due to your GC why not try?

It doesn't actually change the solder into liquid during the baking phase, but softens it, allowing it to rebond. Heavy chips MIGHT fall off on the underside, but the bigger the chip, the more it is usually anchored to the PCB.

my problem same as K.E
and i just baked my GC..done exactly like 1st post..
but it didn't work for my HD3650

1 year and 8 month old Sapphire HD3870

after playing 2 month of aion become like this
now using 7600

i not sure about sapphire warranty =/ mostly 1 year right ? later check ... good night >.<

Sapphire gives 2 years warranty for their cards.

http://www.sapphiretech.com/presentation/s...id=3&psn=000203

Don't cook the card if you still have the warranty.

I guess you need to bake it again...

My 7800GT started spewing out artifacts again after a whole night of Furmark. Oh well, fun while it lasted.

will this method void the warranty?

oh well i think is lower than 50% chance of revival of a dead gpu.

If it shows melting mark or similar....it will be void.

next time they will insert a new t&c on their warranty = hardware baked in oven will result in warranty being void.

Probably yes, as it's quite untraceable. Warranty stickers and labels might look a little crispy and slightly dark though. Don't smoke the card unless you don't have any other option.

RMA it, your graphic's RAM is spoiled. If you use onboard 1, you RAM is spoiled.

try to take out your ram and put it in again
i do encounter the same problem b4

wow,interesting!

is time to baked

The baking works more on nvid*a 8 and 9 series graphics card, because it has a known failure mechanism.

This re-baking process is called reflow in the industrial jargon. Optimum temperature is 180 for the solder melt (yes, turn to liquid). The amount of solder is little, so it won't drip. Do not exceed 210, or else the PCB internal fiberglass will melt.

Another important part is to let it cool down naturally.
It is better to have a certain amount of force pressing the GPU and the board together. Stock cooler is not recommended because force distribution is not equal.
The board should face up, unlike the photos so that the chips will sit onto the board when the solder melts.
ATI did not have this problem.

Good luck.

I questioned the purpose of facing the chips downwards as well, but to be on the safe side I did it according to the guides, which most people followed. Also, I read around that lead-free solder melts at about 210C, the 180C melting point you mentioned only applies for normal solder.

My card's actually still working, only craps out during 3D sessions. Once the card dies or when I have more time, I'll try rebaking it up facing upwards.

Kinda sad for today fail to RMA my GC
the technician said only europe provide 2 years warranty .. for local distributor only 1 year .
Have to wait monday to call sapphire distributor to double confirm

is this true.. omg.. i dont dare to do it.. haha

my mum will be shocked looking at me smirking at her while she saw me put a GC in her oven.. sure later she called the mental hospital..

Always RMA before trying to bake it.

I guess I should mention this. This is pretty much the same way how people fix Xbox360's RRoD.

SUPER COOOOOL !!!!!

Added on December 13, 2009, 3:00 ammy 4850 lasted 3 hours before showing some sign of artifacts...
straight away send for warranty and came back 3 months later...

ati do have such problem... but mostly only hd48xx series does

This post has been edited by general_odin: Dec 13 2009, 03:00 AM

my 4850 also got those artifacts problems..which i think the ram already toasted.
one thing i wanna ask.my stock cooler...from 9 blades,1 of its is already broken.do they accept it if i sent it for warranty purpose?or that count as physical warranty?but my card is broken due to the ram...not because one of the blade is broken

Will test this out asap when I'm in KL yo !

And I will post results.

Good Luck !

is it work for 9550?
maybe i'll give it a try.

After u oven the card, does it has any performance drop on the Graphic card?

i try this method just now but i try with an old wd 10gb hdd.
this hdd cannot detect then i pull out the pcb under the hdd.
after that i put in the oven just like TS did..
Now this hdd working great and can detect.
its really work!!!!

wow this is cool~ recently my fren pc have this kind of prob as well... dunno whether shuld try or not...

can we apply this method to mobo aswell??

I have faulty FX540 and not sure if this method would work? Anyway I wouldn't use our home oven to do it because the smell would linger inside the oven for some time even if you air it.

hmmm...wonder if this works for ps3 too..

Can try modded ones

Wah this mean i can bake my semi dead X1900 GT.... XD

Wokay.

Here's my turn.

ASUS Radeon AX800 all stripped.


Inside the oven already.


Exactly 200 degrees


Smell of flux.


Cooling down~


Put-ted into rig

unsucessful

pity u..

This post has been edited by faizal87: Jan 6 2010, 10:16 AM

ahhhh,
How long u baked it?

really?4 how long you put it?

Smoked my card again, this time taking 12 minutes, until you can even see the flux turn dark at a few solder points. The card now works in games now, but I wonder how long it would last.

8 min

u lucky /b/

interesting concept, wonder if it would work on the hard disks circuit board

yea,it can
try to read older post

I think after this, oven price will increase 10%, especially the ones able to go up 200C.

My question, which heater to turn on? Both top & bottom?

Both, without the fan.

lol.

if got time,i will do wit my previous palit 7600gt.

waliaoweh
i got 20+ GC just lying at my "museum"
mayb giv it a try
no harm ma

Added on January 8, 2010, 10:05 pmthe last picture shown seems like the fan has a contact with the component causing it to short circuit...
just guessing

What about reviving RAM stick, or CPU?

amusing thread
but dont hav an oven to bake my 8800gt which died after 2 yrs with me

oh my geeeeeee... lol unbelievable...

perhaps im might gonna try on my 9800xt lol...

im not sure does this could fix the artifacts...

unfortunately i dont have a baking oven...

cool...

TS, please state in the first post that it's unethical to sell baked graphic cards.
If you would do so, please state it on the top of the first post and put it in bold.

Hmm... I am gonna try with my faulty GTS250 when I got the chance... Want to buy oven now... Or @TS can lend me your oven?

This post has been edited by sanderz: Aug 25 2012, 04:23 PM

You better not buy new oven just for this. Remember, strictly no microwave.

looks and sound dangerous bro....but theoretically correct

this is interesting!

shiat gonna try this with my dsl and adsl board soon!

LOL should try this on my dead 3850 and see

LOL bumping 2 years tred just 4 this?

Hahaha. +1 GC Baking service...

That day I PM @TS, he say his GC died 1 month after 2nd baking... LoL...

Added on September 1, 2012, 12:32 amYeah. My GC fails me

This post has been edited by sanderz: Sep 1 2012, 12:32 AM

Too bad......thought can last until now
still need to move on for new GC.

Before baking the graphic card please beware of the capacitors. If you have electrolytic ones, then remove them otherwise they will bloat from the heat. Also do not exceed 250C to 300C for too long. A soldering heat gun would be the better choice instead of the oven...

Then just get a new/another one...

i think my galaxy 9800GT are having all solid caps....should i try? but i dont have oven

No point actually, the success rates of using the oven are actually very low. You will likely cause further damage and/or kill off your graphic card. If you want to know the true method then check the Youtube example videos below...

might try it, i have dead 4850. now use 7850.

what is suitable temperature for this method and how long?

200C / 385F @ 10mins

I got interested in oven baked graphic card (to revive back dead/ artifact gfx card)
my Sapphire HD 6790 ... suffer from a severe artifact , twice actually, the first time .. I send for RMA, its took 6-7 week.

survive 1 years after the RMA, then of of sudden in end oct 2015. its just boot up with Blank screen & boot in bios with severe horizontal artifacts.
kept it for almost month in box.

then found out about oven baked graphic card online:


http://www.overclock.net/t/1511575/bringin...y-step-tutorial

credit to the KamaYeah

I tried it on my Sapphire HD 6790, and it works.
So far 4 days already, past couple days I run COD black Ops 3 on it. @ medium setting @ 1600x900
So fa so good.

I re-apply thermal paste.

I download the new crimson software run with it.
I change the manual fan in overdrive run it 100%
idle @ 40'C ... Full Load at 58'C

its a common practice in the west..... i have macbook with a dead graphic card which is embedded ..... so i was advised to bake the whole mobo ! which is no easy task...unless it was a desktop !

but the there chances that the problem may re-occur.

i used a hair dryer for my laptop, works for while then kong again lol

is it... doesn't work all the time !

U need more heat, especially with modern ROHS standard, manufacture are required to use lead-free solder which melt at roughly 217C, compare to the leaded solder which melt at 180C. A hair dryer only can provide at best 110C. Try a heatgun next time.
