I start mining ETH again and see that Claymore Miner is not running any more so i start to mine with Phönix miner- Hash Rate is good but i do need much electricity. I live in acountry with 30 cents/KWH. I have 5 RX580/8G -On Claymore i need 600 Watt in 2018 -now i need 1000 Watt/H -same settings in Overdrive N Tool than 2018 - I try  write in BAT Datei cclock 1200 -mclock 2100 -cvddc 850 -mvddc 850 but bothing changed. Does ETH Mining need more power now or why is this so???
