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.

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..
