    Hi. What are you getting on the PCI Pins (12v, 3.3v) and the coil near the PCI slot?

      On The coil 12v, 3.3v and 12v lines from pcie arent shorted. Volts are in. Restistance on 12v in ~100K Ohms, on the 3.3v line 2.6k Ohms. I

      think this card has problem with initialization now, because all lines are working(i think). I dont know how to check communications between bios, core and motherboard. Crystal is getting warm when card is power on, thats why i use small cooler on it to measure voltages when working. I dont have osciloscope to check signals lines. Thanks for advice!

        No problem at all.

        A quick question that may lead into a path to follow for you:

        If the fans still are not spinning, what voltage do you have at the fan connector?

        In your video you said you programmed the BIOS chip so that shouldn't be a problem. Yet, the fans don't spin at all (I assume based on the description). This would mean that there is a break somewhere on 12v rail.


        The scary part is that the crystal/CPU is getting hot. This can often indicate a bad crystal (or at least one that needs reconnected to the PCB).


        So see what voltage the fan is getting. I assume it will be less than 12v. Try to work back from there and I'll see if I can dig up any helpful info from my last repairs on AMD cards.

          You right. Here is photo with fan connector. There is weird voltage on gate i mean 2.8v, i changed capacitos under this gate, and voltage calm down, but 2.8v still exist.

          https://ibb.co/jMmZhyZ
          On second video was 11.80v, card was warmer, so maybe it was the reason for lower voltage than these picture.

          When i get this card from my friend was like that (i speak here in polish). Fans restarting like voltages rails

          This video is before videos in first post.

          Thanks for your help, its my first contact with amd cards (repair i mean), and i'm still learning. In the past i repaired a few Nvidia cards.
