SAPPHIRE NITRO+ RADEON RX 570 4GB - No picture

[nosfay]

Hello,

I got a SAPPHIRE NITRO+ RADEON RX 570 4G that has no picture.

I see no dmg on the board.

Fans and RGB are working.

I can see the card on Windows with an other GPU, but with an error in device management.
When I try to install last driver, it freeze.

I've tried to boot on Arch linux to do a meme test, and it freeze at boot.

Here is my resistance measurements :


Vcore seems low. What can I check next ?

Thanks
