What percent of rejected shares you have? Not percent that showed by miner. Just take all rejected shares and divide by all shares and multiply by 100.
Currently running at 0.54% rejected. What do you think. Too Hight ?
No, it's not too high... But TR even on nicehash gives only 0.3%. You mine not on nicehash?
No, I use ethermine. Started with them way back from day one.
