http://cluster.bitscope.com/I would make a cluster with these boards and put it in a windy place with FREE and GREEN energy. I have the NVIDIA card 750 ti, already in my computer and I know what you all want to mean. But it is unbelieveable that no coders tryed to create a miner for the Mali450 processors and Cortex processors.
Dude this is like trying to get electricity on that island from many many smaller car engines on petrol instead of those huge diesel ones. You can and it could be done, but there is no point in it.
