    RX 470 OC No voltage on the card and zero ohm on vcore

    Yes, I know, but I don't know anything about the history of the card. I have looked at it too and they have a short on the capacitor line and the ram except for the ram but that is not the cause of the fault.

    RX 470 OC No voltage on the card and zero ohm on vcore

    Hi I removed the low side mosfets and tried to inject current (0.8V). But it did not work, so I looked around and found a capacitor with a very low resistance. I removed it and the pci 12V to ground is now in kOhm. So any other ideas where the short could be?

    Thanks for noticing I hadn't noticed. I will look around for it.

    RX 470 OC No voltage on the card and zero ohm on vcore

    That's flux there. I'm going to take the low side fets off and try to inject the current that way. I did it with 0.8V last time.

    RX 470 OC No voltage on the card and zero ohm on vcore

    Hi I am sending you a picture of the card. I have measured the coils and marked them in the picture. My meter reads 0.2 Ohm at idle, I have already subtracted it from the values. red 1: 277 Ohm red 2: 2.45 KOhm green: 4.3 Ohm blue: 0 Ohm Orange: 40.9 Ohm pink: 277 Ohm yellow: 21.8 Ohm

    RX 470 OC No voltage on the card and zero ohm on vcore

    Hi I have a Sapphire RX 470 4GB OC which is behaving quite strangely. No voltage is present on the card except 12V 3.3V and 5V. Another strange thing is that the vcore has 0.3 Ohms to ground. And I tried to apply power here but nothing got hot and I don't want to disassemble the whole card...
