I wonder what would be the risk when a psu has for example 400W at one 12A line and i would power one board directly and 3 others with cables? I could use 3mm speaker cables if that helps...
You risk that the weakest part melts.
The power for the 3 others has to go through the PCB from the direct connection to the green terminal then.
burnin already recommended to only connect two boards and use
solid wires. I would just follow his recommendations.
I wrote it in red and bold, USE SOLID COPPER WIRESupdated status of all orders shipped now.
@BenTuras were you able to get the CAN to work now?
you have to state the number of miners in cgminer correctly.
It must be maximum number of boards in cluster x2.
And i would also suggest setting the fan control target temperature to 45°C.
This is for a stack of 8:
