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?

I'm out of mining since I have a n expensive price of electricity, but I used to mine for some years
With 470 and 570 I used to achieve 27 or 28 Mhs so I'll give some ideas and as always in tech, you'll have to try until find the problem

Samsung are the best memories, so if you see some guys saying you can achieve high hashrate on 470 and 570, it's probably Samsung memories

You can have unstable overclock, put your card in stock and look the behavior, is it wrong? Maybe your card have some problem and need RMA, but if not, your problem could be the OC, most of cases are

You can have a defective Riser (sometimes a bad riser can cause some strange effects)

Check if your power supply is enough to keep your machine working, with a bad PSU you can have similar problems
