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?
