All my rigs are running RX 480 8GB Cards - Mixed brands - Power Color, Sapphire, Asus Strix and XFX (all stock bios)- all running stable for 28 hrs now on v9. Average hashrate - 225 h/s per card. The Asus Strix cards seem to have the best hash rate on v9 (about 230 h/s). All rigs running Celeron Procs at about 10% with -i 8. Intensity settings don't seem to have any effect at all for me (0 to 8 makes no difference). Power usage rose about 6% average but gained roughly 20% hash rate from v8. Kudo's to Claymore. I'm not seeing any of these power spikes everyone is talking about but all i have is a meter at the wall.
