0.79% in Ant 0 and 0.74% on Ant 1.
You are getting 3.04% on yours!!!
I have nothing else than the original heatsink and a fan blowing through them (not from the top but from the side).
How are you getting your U1s to run at full speed with your BEs on 3.9.0?? What is your command line or .conf? When I try running my U1s and BEs together, the U1s run just 20% or so faster than the BEs on my win7 box.
