I have GPU4 watchdog error happening every 6 hours even on factory bios on my Sapphire RX470 OC 8GB (Micron)
How to lower ethereum mining intensity on GPU4 only?
add this to bat file after .exe file (after or before -epool -ewal whatever)
-ethi 8,8,8,8,6,8,8,8,8,8
gpu4 is 5th gpu so value 5 is 6, you can make it anything lower than 8 (default) until it is stable. or keep it cold and decrease mem overclock. or put some dummy dvi adapters in gpu0
