    i5 2400 Will Not Turbo Boost Above Non-Turbo Speed


      Hey all,


      My i5 2400, with a stock speed of 3.1 ghz, should Turbo Boost to 3.2 ghz under full load, and to 3.4 ghz when one core is loaded (taken from the Intel Core i5 Desktop Processor; Turbo boost frequency table). None of this occurs - if I run the Intel Burn Test whilst monitoring with the Intel Turbo Boost Monitor, and with CPU-Z / HWinfo64, I see a 'turbo boost' caption appear on the Intel monitor, but the CPU clock doesn't change at all (either in it or the other two programs). I have tried restricting the IBT to run on only one core, but still, 0 turbo boost increase. Temperatures are good (<50c).



      i5 2400

      ASrock z77 Extreme4 (BIOS at latest)

      8gb G.Skill Ripjaws X (DDR3 1333Mhz)

      HD 7970

      2TB Seagate WD HDD

      Corsair HX750 PSU

      Windows 7 x64


      Any help would be appreciated.
