Had this same issue on my old 5 card rig, it turned out to be a bad flash due to and in combination with a bad PCIE slot on the motherboard. Flashed it on another computer and re-inserted it into the PCIE slot via riser and it worked but due to the bad PCIE slot the system would randomly reboot. This is why I switched to all 4 card rigs.

it can be temperature or pcie problem, because both cards died when plugged in x16 port

What are your temps? Switch PCI slots and add more fans.

It was about 70C, slightly more than average but these should be resistant cards

Test it without overclock, just stock clocks and original bios to be sure that gpu is ok, then test one modification at a time (bios mod, overclock).

Hi there, I have been mining with my new RX 480 gaming x 4gb for about a week, I have bios modded it before, just changed the straps and for mining it was slightly memory overclocked (for eth mining) after a week my pc couldn't recognize it and I found out that it has artefacts. A similliar thing happened to my other rx 480 plugged to the same rig, I am not sure where is the problem, we have changed the psu now... Your thoughts?
