Sapphire Radeon RX5700XT IR35217 configuration

[PeqNP]

Hi,

I have a faulty Sapphire Radeon RX5700XT with a short on the 3.3V PCIe rail. I was able to trace the short to the IR35217 which is responsible for managing VCore. The issue with these controllers is, that they need to be configured. I managed to get hold of a copy of PowIRCenter as well as a compatible USB flash device. What remains is, that I don't have the IR35217 configuration for that card. Does someone here own this card and can share this configuration? As this is a reference card design I would suspect that any other reference card would do the trick as well. The configuration can be easily dumped with any recent Linux system:

DISCLAIMER: Changing values on I2C can permanently damage your hardware. Proceed at your own risk. You should be fine following these steps but I don't take any responsibility if you brick your card.
# First you need to load the required kernel modules
sudo modprobe i2c-dev
sudo modprobe i2c-piix4

# To list all your I2C busses run:
sudo i2cdetect -l

# To list all devices on a specific bus run
# sudo i2cdetect <busnumber>
# For example for bus 0 you have to run:
sudo i2cdetect 0

# At least on a Sapphire Radeon RX5700XT Nitro+ the IR35217 was on I2C bus 3 with the address 0x30 which can than be dumped via:
sudo i2cdump -y 3 0x30

As I have a Sapphire Radeon RX5700XT Nitro+ I can share the dump that I was able to grep from that card:

sudo i2cdump -y 3 0x30

3.3v block
Measure the impedance of pin 8 on the motherboard contacts
If short, 100% gpu is dead

Did you have any success with replacing the IR35217? I have a Radeon VII I'm attempting to fix and leads me to the same conclusion.
