Does anyone know if these A8 can comingle on the same controller as A741 or do they need their own?
From their official site:
"By connecting our AvalonMiner Controller (sold separately) to a single AUC3 (AvalonMiner USB Convertor 3), you may connect five AvalonMiners. For maximum usage, you may connect the AvalonMiner Controller to 4 AUC3 devices which may each connect to 5 AvalonMiners for a total simultaneous management of twenty AvalonMiner 821 to reach 220 TH/s (RTHS)."
With that, I'd say yes. I would think there will not be a new controller, but they might do an update on the firmware eventually.
Edit: Being this is the same controller for the whole line of new AvalonMiners, I'd believe they can "comingle".
The only difference between these miners appears to be the number of chips on each hash board.
(With exception of the A8 integrated power supply)
