Test booting windows and using Intel's Monitoring tool also gives 3.2GHz on a single core if there's enough load.

Intel turbo mode support
Hi, I've stumbled upon http://goo.gl/Aq6Vd in the freebsd-current mailling list and started investigating if turbo mode is working on my i7 860 here.

According to the link above, freq_levels should show a maximum frequency of 2801 if turbo mode is working. The patch above was MFC'ed quite a while ago. I updated to 9-stable yesterday and it looks like the turbo is not working. dev.cpu.0.freq is at max. 2.8GHz, even if I am using some CPU stress testing utilities (like burnP6). I'm really thankful for any input on this matter.
