Turned it on, configured it and it works

It looks like it's running a bit hot.  Does the interface have a way to easily underclock the miner?  What rate and efficiency does it get with the maximum underclock?
I have switched it off again after a few minutes.
I will try to answer your question later.

I have underclocked it to 800Mhz (from 1000Mhz). It uses around 1W / GH/s and produces ~800GH/s.
Switched it off again.

Could you have underclocked it more?  How is the noise level at those settings?  I can't find a proper review of these anywhere...
