Any Body here using 8 GPU board Onda with RX , i have been having problem with GPU0 being very slow , 15 MH etherum instead of 29 and 170 hash xmr instead of 900 .
I'm using the Asus miner board myself with 8 GPUs (2 1070ti, 6 1060s) and I have the same exact issue. All cards run great except GPU0 which happens to be a 1070ti. It runs about 80 to 100 sols slower than the other 1070ti with the same overclock settings.
