Does someone currently mine with RX 470-570? I was curious, how my ASUS RX 470 4GB is doing at mining Ether (Phoenix miner). I strapped my VRAM, i OCd memory to 1850MHz (Elpida) at 900mV. And i can't get stable speeds. Range is between 12-28MH/s. I was trying different settings and BIOS versions, the behaviour is similar, sometimes it's stuck at 19MH/s for 30 minutes then it goes 27MH/s for 5 minutes and then it goes 18MH/s for another 50 minutes and then it goes for 24MH/s for 10 minutes, and so on. I'm on the newest drivers. Is it normal? Maybe it's because 4GB of VRAM is not enough to achieve stable full speed? Or is it drivers fault?
