Hey guys just bought an s4+ that was used. trying to figure out an issue with it before asking for a partial refund. Currently one of the boards, does not raise in temperature. and the unit is underhashing. but the chips show as ooooo in the chain. any ideas?
EDIT:
they show as o in the chain, until about 10 minutes in then all but one switch to x.
sometimes when the s4+ is turned on chain 2 shows 27 asics instead of 51.
And there is no orange light on the board like the other 3.
faulty board?
