Hi, one hopefully short technical question. I have Intel Core i7-3630QM Processor, http://ark.intel.com/products/71459 having 4 cores, 8 threads and running on clock speed 2.4 GHz. It should be automatically overclocked to 3.4 GHz in case of need, but I wonder how this works. Does it require any communication with kernel or even with user? All HW listing tools say it is 2.4 GHz processor, so I wonder how to make it 3.4 GHz one. ;-)

Nowhere any note about 3.4 GHz frequency... Why? Have a nice day, Vojtěch
Hi I'm guessing turbo boost is activated in your system BIOS?
No, there is no such setting in BIOS.
Have a look at the i7z reporting tool; http://software.opensuse.org/package/i7z This will show whether turbo is on or not as well as other info.
It shows # i7z root's password: i7z DEBUG: i7z version: svn-r77-(20-Nov-2011) i7z DEBUG: Found Intel Processor i7z DEBUG: Stepping 9 i7z DEBUG: Model a i7z DEBUG: Family 6 i7z DEBUG: Processor Type 0 i7z DEBUG: Extended Model 3 i7z DEBUG: msr = Model Specific Register i7z DEBUG: Detected an ivy bridege processor i7z DEBUG: msr device files exist /dev/cpu/*/msr i7z DEBUG: You have write permissions to msr device files ------------------------------ --[core id]--- Other information ------------------------------------- --[0] Processor number 0 --[0] Socket number/Hyperthreaded Sibling number 0,1 --[0] Core id number 0 --[0] Display core in i7z Tool: Yes --[1] Processor number 1 --[1] Socket number/Hyperthreaded Sibling number 0,0 --[1] Core id number 0 --[1] Display core in i7z Tool: No --[2] Processor number 2 --[2] Socket number/Hyperthreaded Sibling number 0,3 --[2] Core id number 1 --[2] Display core in i7z Tool: Yes --[3] Processor number 3 --[3] Socket number/Hyperthreaded Sibling number 0,2 --[3] Core id number 1 --[3] Display core in i7z Tool: No --[4] Processor number 4 --[4] Socket number/Hyperthreaded Sibling number 0,5 --[4] Core id number 2 --[4] Display core in i7z Tool: Yes --[5] Processor number 5 --[5] Socket number/Hyperthreaded Sibling number 0,4 --[5] Core id number 2 --[5] Display core in i7z Tool: No --[6] Processor number 6 --[6] Socket number/Hyperthreaded Sibling number 0,7 --[6] Core id number 3 --[6] Display core in i7z Tool: Yes --[7] Processor number 7 --[7] Socket number/Hyperthreaded Sibling number 0,6 --[7] Core id number 3 --[7] Display core in i7z Tool: No Socket-0 [num of cpus 4 physical 4 logical 8] 0,2,4,6, Socket-1 [num of cpus 0 physical 0 logical 0] GUI has been Turned ON Logging is OFF i7z DEBUG: Single Socket Detected i7z DEBUG: In i7z Single_Socket() i7z DEBUG: guessing Sandy Bridge And when I watch it for a while, it shows sometimes frequencies over 2.4 GHz, so it seems to be working, just not reporting for ordinary tools...?
