I can't see many threads about the RX 590 8gb OC but unfortunately I've been experiencing the troubles with graphic card. I've tried a lot of "workarounds" as described among th e different thread i've read so far, nothing really worked better. Black screens, sound going on for a few seconds then back to Windows (when I'm lucky)... I tried to underclock my GPU from 1565Mhz (OC Clock) to 1545Mhz and it works ! The thing is the software can't seem to keep updated the new working settings... Any idea people ? Thank you
