What action did you guys take when one of the 4 cores stopped working? As though its not already bad with 20% less hashrate now one of the cores has stopped working reducing the hash rate to 1.2 Th/s.
Just restart cgminer from the config tab.
No luck restarting cgminer. I also restarted the machine both using Restart System option and hard booting it. The 2nd core of CTA0 appears to be hosed. I have left a voicemail and sent an email. Hope to have this resolved ASAP with Cointerra's asistance.
I had to ship it back to Cointerra(they paid shipping both ways) to have the pump fixed. I still don't know what exactly got fixed but I got it back today and after 2 weeks of downtime its hashing away again.
