Well 2 of the units came in from BitcoinMerch tongight and I am not having much luck with one of em..
1 seems to be spot on from the factory.
The other I am not sure why but it doesn't seem to be coming to life or getting anywhere near the hashrate it should.
I've swapped USB cables, tried a different PSU, tried only 1 R909 but no luck

Anyone have suggestions?
