Reported hasrate is 145.2 like before dag average hasrate is higher by 3-5% then on rest of rigs also number of shares much higher... only problem i jave is that i csnt undervolt cards as claymore making spikes one second voltage go down then other second return to default and afterburner voltage settings also dont work.. any solution for undervolting?
