I have been trying to setup my blade (latest version) and I can only get 2000MHS to 38000MHS. I used a 2 molex to PCI-E 6 pin adapter for the power adapter with a 600W PSU (48A on 12V rail). I have each yellow wire going into the + inputs, and the doubled the black wires up for each - inputs. Please see my config below, as I do not see anything wrong with it. Also, there's no instructions for the new blade.
