Greetings,

New to the msg board and crypto mining, not new to bitcoin.

I currently have the following hardware mining successfully on nicehash:

i7 5820k
MSI x99s Plus motherboard
4x4gb ddr4
RX480 x 2

I have the 2 480s bios modded and clocked/volted with afterburner. Working great, very stable. On the latest AMD drivers released 11/2/17.

I wanted to add a 3rd card with bone stock settings (asus strix rx570) that I would use to display/game while the 2 480s churned in the background. When the PC was sitting idle I would begin mining with the 570 as well. That was my plan at least.

When I install the 570 it all goes to crap. The 570 will work initially, then the display goes black. If I switch the hdmi to a 480 for display, I can no longer see the 50 in windows device manager.

Would there be some driver conflict because the 480s have modded bios and the 570 is stock?
