Do other video cards work?

This one sounds dead.

Not too sure

Are you sure? I don't think its dead,we cleaned every oil in there,and put it back.I will investigate more to get some info.

And how can you throw away this post like a toy? You should question something rather than simply saying 'Dead'.If i can fix it,you'll see.

When you spill oil on electronics, the prognosis isn't good.

I see they have them used for $79 at Amazon. How many hours of your time would you want to spend to avoid a $79 expense? Most folks would spend the $79. YMMV.

79$ is expensive as hell here

You probably don't know where i live.I live in Turkey,so 79 dollars is hell expensive for us,because $ is raised here.And yes.I will spend time to avoid 230TL(79$)

I wish you good luck, but I'm afraid I can't say I'm optimistic. I remember seeing an Intel rep saying that nowadays they can put a million circuits on a pencil point. That means circuits are microscopic, so I can only imagine what microscopic bits of oil could do to change the electrical components characteristics.

You are right

I am afraid you are right.Damn you cousin! Why the hell you supposed to pour oil and corrupt nice GPU? whatever.Looks like it will stay as a decoration.

Can we replace GPU's chip?

Hey man so I was looking for new gpus and i came up with an hd6850 xfx with its chip burned,and it was only 15$.My sapphire's chip is fine,so can we replace xfx's chip to sapphire's chip?

That's for you to answer.

Either you can work on such things or not. It's a skill and gear you have or not.

So?
Sep 1, 2015 10:53AM PDT

You talk very mysterious Happy so you mean you can replace chip but it depends on your skill?

There is no mystery at all here.

Either you have the gear and skill to change that chip or you don't. I used to change such about 10 years ago but as prices plunged we stopped doing that.

As a test
Aug 29, 2015 2:27PM PDT

I swap in a working card or take this to a working PC. Spilling any liquid, oil or other is not a good thing.

I didn't throw away this post so I guess you meant someone else did. As so few cards have been repaired over the years, it's time to test as noted.

Tests done
Aug 30, 2015 8:22AM PDT

We already did,but i cant still understand.No oil left in card,chips, fans rams are working, but black screen? Hell why he did pour oil seriously? Stupidness.I will still work on it guys.I just want to use it because I don't want to spend money to GPU because im planning to get G25.
