I have purchased an RTX 2080 which contains a scorched component. I have carefully removed it with a heat station. The card is not short and it works, but it is seen with artifacts.

The problem is that I cannot find the characteristics of the component anywhere. I am going to attach a photo in case someone has the same graphics card and can measure the component or if someone knows which one I have to buy. I would really appreciate itIMG_20211106_005351 (1).jpg

thats look like an inductor, check its pad if it is connected to ground or not, if not grounded any of a pad, then that should be inductor.

IMG_20211217_173554.jpgAs I found on the internet, I believe this is a ferrite bead. I went ahead and measured the size of the component and I think it measured between 2mm x 1mm and 1.6mm x 1mm. The problem is that I have no idea how to measure a ferrite bead or where I can find the characteristics for this component.

@Borges okay then its a EMI filter, if you have any other donor board take it from them and solder on this board, you got schematic for this board?

I have a few faulty GPus, but I dont see any component with LB-XXX on the PCB

Also, what you said about the EMI filter makes sense. This is because I already removed the ferrite beads and I still get artifacts when I turn on the PC.

Do you think that not filtering of the electromagnetic interference is causing the artifacts or the problem is from another component (maybe the RAM)? Also, can I solder a ferrite bead of similar characteristics (a ferrite bead of the same size) or does it have to be the exact one to not mess with the circuit? I am not really certain on how ferrite beads and EMI components work.

can you upload a photo of that artifact then let see. EMi filter used to reduce noise from the signal line. that wont cause that kind of issue i believe .
