Title: RX 480 - artefacts Help Post by: shadowhlohavec on April 10, 2017, 11:31:50 AM 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?

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 was about 70C, slightly more than average but these should be resistant cards Title: Re: RX 480 - artefacts Help Post by: shadowhlohavec on April 12, 2017, 09:05:20 PM 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.
