Hi
Just want to say that this is the best cryptonight miner. I have rig with 3 XFX RX570 Black Edition 4GB cards (elpida memory) and 2 Sapphire RX580 Nitro+ 4GB cards(samsung memory) and i am getting around 945 per RX570 and 986 per RX580 cards.
For 570 cards I use 1200,875 for core and 2040,880 for memory.
For 580 cards I use 1200,870 for core and 2200,880 for memory amd my rig is pulling around 500W from the wall. I am getting some memory errors in HW Monitor but no incorrect shares (100% accepted).
I use overdriventool to clock my card but problem that I have is that sometimes if I restart miner, clock and voltages on my RX570 cards is reseted to default and then I need to restart my pc so overdriventool can apply clocks again. Because of this I need to keep watchdog turned of.
Now I don't know if this is a problem with miner or overdriventool?
