Defective rtx 3080ti, Help!

[glodcast]

Hello, I reacently bought this gigabyte master rtx 3080ti 12gb as defective. The card lights up and the fans spin to life, but there is no video output nor does it show up on nvflash. I checked the PCB and found these two (somethings) solderd to eachother. I cannot seem to find any info on what these do or how they are configured and I'm simply not shure what I should do so I'm asking the other repairmen here; What are these components? What do they do? Might they have shorted and just fried the gpu? Is it a bad idea to reheat them and reseat them propperly?

I'm thankful for all the help I can get!

Caps also go to www.northridgefix.com and send them an email

Your first issue is buying a known defective card without knowing how to fix said card.

As you bought it as defective knowing full well there's a big chance it won't work regardless, could be physical/trace PCB damage, hairline/under die damage, vram, solder joints etc etc the list is endless

You rolled the dice hoping to win though most of the time the house wins, not sure how those 2 components could have come together like that naturally tbh and maybe aren't the (only) issue with the card not posting or being recognised when plugged in/powered on though I am just using guesswork at this point, would be helpful if you clean off the TIM and clean the PCB down with isopropyl alcohol and inspect the whole GPU before putting all your cards on those 2 caps/SIMD components being the reason it won't work. That said you if you are capable at soldering electronic components, it doesn't look like the hardest job in the world to de-solder them and solder them back where they should be, not sure if the outsides are even conductive, someone with more electronics repair experience could probably add more context.

Good luck though, assuming you bought it for a very cheap price if you can get it working then it will be a big win for you, until then, just consider the $ you spent on it as wasted and move on

A little hard to tell from the shadows, but it looks to me that those crooked chip components, I'm guessing capacitors, are sharing a common bus at that point and it probably doesn't matter that they're touching above board -- though that is sloppy construction (or a previous owner messed with it).

This. Thats a pretty common and normal situation

Use a fine tip soldering iron, some flux, and tweezers to reseat that Capacitor.
