After 7 hours Ive got 9 hw errors and 17 block expires on nanopool. Is this normal? Whats most worrying are those hw errors. HWinfo reports no errors, though. Really appreciate your opinions.
expired block means the share you sent got old because the block expired in the meantime.
Hw error means gpu result did not pass cpu validation. So if you want try lowering intensity, or mem clock for ex.
