Dead 980 Ti

[Darchitect]

Hi my school teacher's graphics card died from an electrical surge via the cat5e cable for internet connection. He said that if I can fix it I can have the graphics card (A mighty good upgrade from my 680). Does anyone have any ideas on how to fix it? Please post anything you know and tell me if you are skeptical if your idea will work. Your help is greatly appreciated! Thanks for your time.

 

P.S. I have watched the oven method but I don't think my parents will let me get a toaster oven that will only be used once

Once a card is broke its broke I wouldn't even try to do the method linus did e.g. PUT A FREAKING GPU IN A TOASTING OVER.

Well it did work

Once something gets a surge its game over let me give you an example say a surge goes through a light bulb POOF it will NEVER work again. But in the case of the GPU the Chip that goes all of the graphical work would be dead it isn't a matter whether the solder is fucked the card is literally DEAD.

Why does your teacher have a 980ti?

Is that even possible? An Ethernet cable frying a GPU?

He said that he was using a surge protector and the only power delivery was from the cat5e

this is off topic but I will tell you that he is a very big gamer and has VR

Unless he was doing some Power over Ethernet shit (don't know why in hell you'd direct it towards the desktop) that sounds ridiculously unlikely. Did he see a spark?

As far as I know he did not. But his new 980 Ti works fine in the same PCI-E lane.

(I also tried it in my rig and it didn't work so the card is the problem)

The problem is that it's a very temporary solution and you are effectively making the oven useless due to all the fumes that will be in there getting into the food. In addition, if a card is broken and has nothing to do with the GPU, cooking it in the oven will do nothing. The reason why it worked for Linus is because he was able to likely allow the adhesive material in the GPU to become soft, allowing the solder ball(s) to move back to where they need to be, allowing the GPU to function temporarily. 

 

He never reflowed the solder as he suggested in the video. Solder reflows at around 550-750 degrees F.

I would think its next to impossible to achieve this sort of problem even POE (Power over Ethernet) really doesn't have that much juice going through it.

 

absolute maximum power transmitted using direct current is 50 V × 0.360 A × 2 = 36 W

are you saying that there is no way to fix this?

I probably should have said that his router also died at the same time

I'm not saying that, but it depends on what component is non-functional, and if anything is destroyed within the layers of the PCB. Sometimes resistors can be within the layers and one of them could've become damaged in the surge.

Is there any way to identify the issue?

Is there any physical damage done to the card that can be seen? If you've seen the card anyways.

[bobman279]

I have a solution take that card down to your localish E Waste disposer give it to them if they want money don't bother put it in a shoe box and remind your self to get a POE ethernet surge protector. Job done.

there is not. I spent some time looking at it. Now that you say it I think that I will compare the card to a picture of one

If there is no physical damage that is visible to the naked eye, I'm more inclined to believe that the damage is within the PCB or in the GPU. That being said, components could be damaged without showing it, and it'd be very difficult trying to narrow it down.

I am going to kindly ask for you to stop commenting on this for you have provided almost no useful info except for the fact that I'm wrong. I am not going to give up this quickly.

Even NVIDIA couldn't fix this.

Unfortunately, I have to agree with you. Troubleshooting this would be very difficult. Far too many components to narrow it down, and it could be internal as well within the PCB.
