Rx 570 memory controller burn !!!

[Leloop]

Hey guy's,

I've had an xfx rx570 for a long time and with the shortage of cards, I'd just like to repair my card. So I opened the card and immediately noticed a big problem!
One of the two fm25Q02 chips ( 1802TOG ) burned out! There was also some kind of liquid in the vrm, something like flux . Anybody have an idea how to replace this chip ? Do I need to flash it?
I am attaching a picture, maybe you will be better! 
Also small question, how to know which vrm pins are connected to the ground? Just with the datasheet?

I am Probably very late but that there is a bios chip, and the liquid on the MOSFETs is oil from the thermal pads most likely
