Hello, I am trying to use the new 5.0 for a2 mega (i think, bought second hand on ebay) and it starts, and then slowly dies.... i am trying to run it at super low level, 700mhz to see if the hw errors go away.. but to no avail.
starts fine after power-on boot,

......etc
then I get a lot of invalid nonce errors...
and then it slowly dies when trying to reset the boards

and when it has tried to reinit the boards, it just sits there..
if I try to restart cgminer manually this is the error:
