So I managed to connect to fairpool.
Some stats. For GPUs used claymore 11.2 and 11.3.
Hm. I used 11.3 and official pool - no luck connecting, only errors.
So now I'm using xmr stak. Pool predicts 10 coins for 4 kh. Several hours ago it was 20 coins.
Which pool predicts 10+ SUMO for only 4kH? I'm closer to 55kH and receive in the low to mid 20's. AFAIK fairpool does not have any weird predictions and they've almost always been accurate within a closer margin of error.
