Yeah, I only have a one card. I've never had a crash while mining, I hope I don't. Thanks for your comment.
Better use MSI Afterburner for setting
Core 1150-1200
Power limit -10 -15
Memory from stock values up to 2100.
I have problems with higher memory frequency 2000 on AMD RX580 8 GB
my settings is: -30 max frequency (952 mHZ)
-30 power limit
-100 mHZ for RAM (1900 mHZ)
Core voltage is 0 (i don't use)
I just hope this problem comes out while digging. I don't want to mess up the card.
-30 power limit is also a very large decrease
Try at least 1050 mHZ and -20 power limit and see how the video card works. But it is best to make settings using a wattmeter, then you will see which settings affect energy consumption and which do not.
