Hi Brad,

Can you please share how many RX560 Sapphire you have and what AMD driver you use ? As I tried @privet mod and it's all fine, getting nice MH/s, but after 2-3 mins the miner crash with error GPU# hangs in  OpenCL call exit.

I'm suspecting some motherboard issue, as the 2 PCIx16 slots are behaving very strange. When all 6 cards are connected the PC is really unresponsive, when I remove 2 of the cards which are connected to the PCIx16 the things are much better, anyway I have to test what's wrong there, but curious about how many cards you have running with the bios and for how long + what driver you use ?

Thanks in advance.
