My crew is new-ish to mining, our "guy we know" has done this before with the USB miners and long scrypt and has been a big help.
We picked up a 30GHz-38GHz ASIC Block Erupter Cube and are running it on a Corsair RM650.
The miner's hashing at approx. 50MHz when it should be running at a minimum of 30GHz. The blades were loose when we opened it up, but everything seemed to be attached correctly and is now seated properly.
