My last question is I get high mhs on first run. After a few minutes the mhs goes down and stays constant, any solution?
I see that the coreclock of your gpus are all different. It's probobly because they trottle. Not enough power or too much heat. You can increase the templimit, but not sure if this is the problem.
I brought all my rigs to your miner. However, a rig gave an error. The only difference now is that it's connected to wifi.
