any idea whats wrong?
after start it is minig about 2min, than its stop and blinking red.
You might aswell have wrong atached coolers to the board, i did have the same problem at the begining
When I set up my first miner, I was unable to get 400 gh with 1024hz x .820v, (It, in-fact was doing about 1.5gh, dropping and then becoming a zombie) but that is probably because I am using a 520w psu with only 16A + 18A power. I was, however able to get a good 360gh by setting the frequency to 920 and the voltage to .780. The miner has been up and stable now for 3 days. I think it is worth a try.
