[SOLVED] Baked r9 270 don't work anymore

[sfnstc]

Hi everybody,
I recently bought an old pc from a friend for a small amount. I used it for some days but graphic card was sometimes crashing and sometimes displaying some artifacts so I decided to bake it.

10 min at 180 C, let it rest for 20 min and applied new thermal paste.
Now I mount it, start the PC and nothing get displayed.

Some facts:
gigabyte p55 ud3l
2x2gb 1333mhz ddr3
i5 760 no OC
R9 270 asus

GPU fans work, the green light is ON but it seems to have no signal in output.
triple check on cables and tried 2 different monitors.

Any idea on what happened or how to make it work?

Look at the temps in this thread -- http://www.tomshardware.com/forum/293183-33-baking-graphics-card-oven#6940388 I would suspect that card is ROHS (lead free) and your 180C wasn't hot enough to do anything to the solder.

But, you bought a broke thing, did some unapproved stuff to it and it doesn't work. What did you expect? A miracle?

Let's say I would not expect to make her completely die definitely

Anyway, I'll try to bake again at higher temps, thanks for the suggestion

I hope you're not planning on using that same oven for food after this.

Just baking a card won't resolder a dry joint, the GPU will need refluxing to allow the solder to reflow and create a decent solder joint. It needs to be done on a proper reflow setup with a proper reflow profile, otherwise all you're doing is baking the components on the board. Most components are only rated at 250c for about 30 seconds on a reflow profile.

And this is even if the original cause was a poor solder joint.
That is completely unknown.

So you're saying that a normal oven probably won't fix anything?

Probably not, or any oven now that it is not working at all. And you don't want to use a regular oven because the card will have all sorts of fun dangerous chemicals that will be released during the process.

When I worked for a company that made ovens that made microchips (CPUs, etc..) during a visit to IBM they were showing us the tanks with chemicals and were telling us how long it would take for each one to kill us. Some were in the under 10 second range. Fun times, wearing a bunny suit, inside a giant box with deadly chemicals.

Thanks everybody for your answers.
Costs for repairing the gpu wouldn't match the benefits so I trashed the card and bought a brand new gpu
