These are really nice hubs. I have 3. I high recommend them. However, they only run about 28-34 U1's each. Still, the bang for the buck is great and they have great resale potential. A++
By the way, I recommend CanaryIntheMine for escrow
I can't confirm that. Mine is working with 49 U1@2GH (clock=x0981) for several weeks now. It's the newer version with 12V 6-pin PCIe connector.
