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.
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?
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
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...
