Gigabyte R9 390 8GB Burnt. |GIGABYTE Radeon R9 390 8GB GDDR5 512bit (GV-R939G1 GAMING-8GD)|


Mar 16, 2021
Hello Guys!

I'm new to the forum and I need help with this, can anyone help me?
Some of the integrated circuits is completely burnt. If anyone could tell the name of this circuit(in the middel of the yellow circuit) I may be able to buy one and fix it. Maybe if you have a high resolution pictures from the card, both side, without burnt ic to help a lot!
Thank in advance!

Are you able to read any of the markings on either one?

The smaller of the two components (near the PCI-E connector) could be almost anything, but it's probably a logic gate, diode or transistor of some kind. The larger component near the fan header is most likely some sort of low dropout regulator, but could also be almost anything else, and it's going to be very difficult to tell for sure without reading the markings on them.

You wouldn't happen to have a second one of these cards you can read the markings on, would you?
If you have a jeweler's loop you might be able to take a real close look and try to get more info off there.
Heya! This is what can i get from the 390 i have. Not much but i hope leads to solution.

Card is XFX R9 390 and the way it looks around the fan connector is different. But since in the "power module" in the same area i see only 1 similar IC i think it is the same or similar.
