I have weird behaviour with x13, at first it starts to run around 10.2mh/s
within 4 hours it has linearly dropped to around 9.4mh/s.
today morning after waking up, after 8 hours, it had dropped to 8.7mh/s
and it seems to be linear drop, any suggestions?
I've noticed this behavior on one of my rigs too, it starts out at 13.5 Mh/s, 10 hours later its down to 12.7, temps look fine, and I'm only running single thread configs. It requires the whole system to be restarted in order to bring the hash rates back up, very weird. Using Win 8.1, Catalyst 13.1 (maybe I should try 14.4?)
