Hi there Anders,

So I'm sure I'm checking the right way, but I'm not sure how to
alleviate the situation. I have an i7 720QM in my laptop. I run in
powertop it says I'm in turbo mode. I also check i7z and turbo stat.
When I'm running the latter two applications it never exceeds 1.6ghz
under full load. Turbo boost on my laptop should be up to 2.8ghz. I
have yet to see this on Linux. On windows it properly gets to that
number while benchmarking. I'm not sure what it is. Let me know if you
have any ideas.

Thanks,
Dan
