Hello


I have question
How can I check if Turbo Boost is working with Xeon E5649

I have turbostats that shows:

So 2.67Ghz - but based on Intel spec max Turbo freq. for this cpu is 2.93Ghz
http://ark.intel.com/products/52581/Intel-Xeon-Processor-E5649-%2812M-Cache-2_53-GHz-5_86-GTs-Intel-QPI%29

Is there any tool that can show me good turbo stats ? or turbostat is ok 
but i have something wrong with Bios settings ? C-STATES ? pm governor ?

Thanks
Pawel
