So, I figured out that I could take my bricked A5 and connect the ASIC boards into the controller board of a working A5 and it works fine

The bricked A5 provides the power and cooling and the working one now gives the workload to all the boards.
Only problem is it only seems to detect 5 boards. 3 from it's own chassis and 2/3 from the bricked A5 even though all 3 LEDs are on.
Any ideas why the controller is only detecting 5 boards out of 6 connected?
