Not sure if I posted this in the right place, but I'm hoping someone can help. I just set up a new rig and w/6x 480's. I'm running at a steady 23.7 Mh/s per GPU, which barely pays the electric bill. I'm running ethOS only and I've tried to adjust global settings, but no difference. Can anyone help a guy with very little computer knowledge either flash the GPUs or work me through ethOS's ATIflash? TIA!!
