Been reading this thread since day 1, and sorry for those that lost money.
But Im confused...when did a 7khs board become a 20khs board? The original post said Dwarfminer did 7khs. All of a sudden we have bittube guy involved saying board does 20 but its not stable? Were there 2 different versions from the same people? Or were there 2 different boards from two different places?
