pretty hardI am that sure . <| sep |> Probably instability . Raise your voltage higher . Maybe , but my build seems pretty stable right now . I ' m at 4 . 3 GHz , 1 . 24 V , and I haven ' t had any crashes yet at these settings . I was able to run Prime 95 for a few minutes I manually stopped it only because temps were getting too high and I was able to run Battlefield 1 maxed out for over an hour . If I do raise the voltage , how much should I raise it by ? <| sep |> Engine over the rear axle gives great traction . <| sep |> Meh , most of them started signalling 8 MB after Core developer Gavin said we should raise the blocksize to 20 MB a while ago . So it was indeed a conservative reaction to the western world . Right now , it seems like only BW Pool 10 % is still putting that in their coinbase text . That being said , I personally have no idea what Chinese miners want .
