Bricked graphics card

[Radic2412]

Hi, I bought a mining card Amd Radeon 480 8GB, it was tweaked and I wanted to change Bios to default. I wanted to test the card first but it doesnt show in the task menager so every benchmark i tried says that i dont have a graphics card so I cannot test it, it only shows in the device menager but with an error yellow triangle, I just want to know if that is normal and if I can safely install default bios on it? 

Sorry for my bad english

If it displays an image then it's not bricked. Make sure you flash it with a compatible bios from the same manufacturer with the same brand of memory. Use GPU-Z to check what is on there first.

 

Flashing a bios is always a risk, if you do proper research first you should be ok.

 

If you are not sure, email the manufacturer the serial number. Most board partners will send you the correct bios if you ask them

Anything unusual about it? But is it still normal for windows to not recognise i have a graphics card at all?
