Can this rx6600 GPU be repaired by soldering?

[jin148]

It's an rx6600 GPU. I tried to attach one of the fallen resistors. The result was failure. They all fell off. I'm not even sure what the resistance value is. When connected, 32 and 42 were measured. The strange thing is that after I removed it, the resistance value was not measured. The resistance was too much. It's small, but is it something that can be done with a soldering iron?

Those look like ceramic bypass caps to me, not resistors (though a bit difficult to tell 100% through the pictures.)

Either way, whether or not they can be put on by a soldering iron depends on the soldering iron your have and a bit on the pad size. On chips like this, the pads are pretty small, so manual soldering with an iron can be more difficult. Hot air with a fine nozzle might be the better way to go. And use a good amount of flux too. Won't get anything to stick without it.

I wouldn't recommend using hot air right next to a GPU die and on top of a BGA. Soldering iron is fine as long as it's a good one with appropriate tip and decent leaded solder. As always, must have correct tools when working on sensitive electronics like this.
