Does it support Grin with AMD (rx500 or vega series) cards? I think it says it supports AMD overall but not sure about grin?
I'm using GrinPro 1.1 through AwesomeMiner for 4 XFX - AMD Radeon RX 570 RS Black Edition 8GB GDDR5 PCI Express 3.0 Graphics Cards (RX-570P8DBDR) and I'm getting 6.4H/s at ~525W. I have a feeling that it can perform better but I can't figure out what's going on with these cards. I just installed them so I haven't flashed any bios or anything. I was actually reading that I didn't have to because it has the dual bios switch (handy.) But for ETH I'm only getting ~110MH/s for the four cards. So I'm guessing that 6.4H/s is going to be about as good as it's going to get.
