Hi

I would like some help identifying the resistor so I can order a replacement it fell and the resistor came off

its an r9 390x


Thanks

there was a resistor there before I have an identity card and there is a resistor there and theres clear marks of force on the area it was working prior to this happening and the gpu chip does get hot when trying to boot which usually means the chip is fine
Unfortunately that location lacks any RefDes marking so it could actually be a capacitor.

Just because the GPU is getting hot doesn't mean it's fine because you haven't any idea which solder ball contact was cracked. Does the card operate? will it return a display?

Lastly: do you have means and skills to solder a chip component onto the board without burning it up? I'd suggest you...

Pictures?

For what it's worth, resistors don't just 'fall off' even if dropped. It most likely struck something that scraped across the board pulling the resistor off...and likely damaging more parts.

I don't really see where a component might have been pulled off... but then the pictures aren't that clear when zoomed in. Did you find the part itself? Can you get some close-zoomed pictures of that? from both sides?

What I do see are quite a few locations without components installed, but that's really quite common. MFR's frequently forego installing de-coupling capacitors when they can get away with it since they're not always needed.

Have you tried operating the GPU? Even if you have, it didn't work and you're just assuming one of the open locations is a missing component that may not be the cause. The more fragile thing is the solder balls on the bottom of the GPU chip. They can often crack when shocked and that's very possibly what happened in your case. Fixing that would mean reflowing the solder balls. Something do-able, probably with low odds of success but if it's a binner already so what? At any rate, it's not worth trying until you've exhausted everything else.
