ahh ok awesome I put down the clock level from 250=2GH/s to 225=1.8 GH/s and the HW errors droped from 70 after 15min mine run to 3HW error after 15 min run... Can we now automaticly point our fingers at the USB Hub and say "BAD USB HUB" or is that not prove enough to blame just the hub for th errors. As I understand, more gh/s more needed energy?
Unfortunately, no. There could be any number of reasons for low power. I've had hubs that didn't like to give good power to certain ports. It could also be bad voltage regulation on the miner itself. The only way to be 100% certain is to take the hub out of the equation.
Also, yes, .bat files are the way to go.
