now just one minion to that power supply
That's it, your PSU is very powerful but not single rail. Your PSU had six rails, each rail only can deliver 30A max.
Using default setting the board will use up to 40A(i guess since i don't own one
)To prove this you can try to disable 1 chip & see if the board can reach 300G
You can see more detail on cgminer api log.
I'm using a psu with 36a on the 12v rails and it works fine.
Of course it work. based on 2GOOD review at default setting it will use about 430 watt.
Your PSU can deliver 36 A x 12 V = 432 watt.
macher PSU 30 A x 12 V = 360 watt, the psu overload protection should already kick in.
no, the PSU is not the problem because it is connect to two 12v rails (2x30A)
You might aswell have wrong atached coolers to the board, i did have the same problem at the begining
no, that is also not a problem - if you connect it wrong, the fan is not moving
I tried to disable the chips one by one and only just one configuration is working - the 12 (0+1 disable). All other possibilities = ZOMBIE
I think that the board is bad... but maybe is between chair and keyboard ;-) I have other 3 boards that is not connect so tomorrow I will try it.
Now the best result:
That is not what meant, i know that if connect the fan wrong it wont spin. What i mean is to drive screws of the cooler a bit harder. I had the same problem as you and it worked
worth a try
