have you tried with a different PSU ?
yea...switched out totally from a 2400 watt to a 1200 watt...but still same thing when I power up.....
can you connect just this avalon to a controller? no other 741.. and try to look in CGMINER API Logs... let's see if it says anything..
got it....will give that a shot....thanks...come back to ya....
You might also try a different port on the controller, and also different AUC cords.
I haven't had this work for me, but worth a try after ruling out PSU or cable issue.
Though I don't think any of these work beyond swapping PSU, since it would be an all or nothing issue with the port, controller or AUC cable, and since it's partially working, don't see how it could be that.
