GPU-Z reads 0Mhz core and memory clock??

Test the cards in standard (non-mining) desktop if you can or in your "another friend's" PC. If they work then its problem with your PC, if they don't then its clearly problem with the cards.

If you cant get signal out of these GPUs then they are probably bricked completely, beyord repair most likely. If you plug it in motherboard and then start playing then you are running off of the integrated GPU not the actual AMD GPUs.

You can also try updating motherboard's BIOS. But chances that it helps are really small.

Thanks for trying to help me out. The cards work totally fine, it was my system who fucked everything up. I don't exactly know what part of the hardware but the cards seem to work at my Friends pc just right.

Just bought a whole new setup and also got 2 differend Rx480 cards. Again same problem lmfao, seems like i have some bad luck. I installed the 17.7.2 driver of AMD and it seems to pickup the card correctly, finally!

But for now,

In the newer versions you are able to switch gpu from graphics to compute mode. Is this also possible in the older drivers like 17.7.2?

Thanks all for helping!
