Issues with mining stability - RX Series

I have been trying to mine XPM on and off. I keep coming back to the same issue. Eventually one or more of my cards will crash. There doesn’t seem to be an Intensity setting but individual tuning settings. I am running 1x RX 480 / 2x RX 570 / 1x RX 580 on Windows 10 x64 with AMD 17.4.4 Drivers. If anyone is able to provide some insight into stability. I would love to mine this coin!
