I got this X850XT from an eBay seller who had the great idea to put a cooler from another model on it.
The cooler had two heatpipes directly sitting over two of the memory chips, so the seller just removed the two heatsinks from the chips.
Lesson learned: Some people are idiots.
The card had some graphical corruption in games which went away when I pressed my fingers on the chips, so this was a classic problem with the BGA solder balls losing the connection.
I've decided to reflow both of the memory chips with my hot air station but I went a little too hard with the heat and one of them released its inner secrets violently.
Lesson learned: I am also an idiot.
The card still tries to put out a picture, it just looks like this:
So it basically works, I just need to source these BGA memory chips and replace at least one of them.
I've searched far and wide but I can't find any source that sells these chips (apart from some chinese websites where you have to buy 10.000 of them).
They are K4J553230G-BC14:
Maybe there are compatible models that are a drop-in replacement or some cheap cards that also have them?
I really don't want to throw this card into the trash, it's a great card (very fast for 9x) and needs to be saved.
