Hello,
I am very sorry if im wrong here but i didn't know where else to ask.
I recently got a Gigabyte rx480 gpu that didn't work. When i took it apart i noticed a small chip that was burned. After searching for ages i couldn't find anything with the numbers written on it.
On the board itself it is labeled pu1 and in the chip i says irc 3958.
If anyone knows what chip it is, what its used for or if its possible to buy a replacement id be very thankfull.
It would also be interesting to know your thoughts if it was the cause of the gpu failing or if it was just a victim.
Sorry again, im very new to more complex electronics but id like to learn more.
