Hello guys. I have a problem and hope anyone could give me some insight. Yesterday i mined this coin with my 2x RX480 but then switched to ETH and my hashrate has gone down from the usual 48MH/s to 34. Also ZEC just gives me 500 sol/s. Ive been mining a few months and its not a single GPU that gives me the problem since both of them give me 17MH/s. I checked all cable connections again and cleaned the dust in GPUs and PSU. What could be the problem? Thanks
