    Problem with Turbo Boost !

    Pierre Romani



      First, I would like to thanks you for the help you could give to me.


      So, it's now 3 days that I have seen that my processsor (Intel Core i7-3630QM 2.40Ghz) is stuck at 2.39Ghz.

      My laptop is a MSI GT70 0NE, I bought it 6 month ago and the turbo boost technology was working, because the monitor was showing fluctuations between 2.4 and 3.1 Ghz.


      But now, it doesn't go upon 2.40 Ghz !!! I tried a lot of things (Intel Processor Diagnostic Tool / Intel(R) Extreme Tuning Utility / My BIOS is up to date...)

      I'm sure that Turbo boost is working but not as it should... Intel speed step is enabled (I tried to desactivate it but this doesn't help with the problem).


      The only way to pass 2.40Ghz is to overclock the processor from 100Mhz to 105Mhz with Intel(R) Extreme Tuning Utility (which I could do only once, I don't know why I can't do it anymore... )


      Could anyone please HELP ME ??


      (I've got Windows 7 and I'm French if this can help)






      I've just seen something which is really scaring me, in the system information window:

      it's writen that my processor is a Intel Core i7-3630QM @ 2.40Ghz, 2394Mhz, 2 core(s), 4 logical processor(s) instead of 4/8 !

          Ok I resolved my problem.


          click on start button, type msconfig in the search bar, then press Enter, then go to start, advanced options and uncheck the number of processors and memory limit.

            Hello Pièrre,


            Thanks a million for your easy to implement solution.


            Not only did this enable the turbo boost function, but it also brought back the 4th core of my i7-3610QM processor which did not work before.


            I don't know how this checkmark got there, nor why the number of processors was limited to 6.


            I am running on the W7-64 which I had cloned from a previous laptop with a two-core processor.


            Keep up the good work
