For troubleshooting purposes what you may want to do is confirm/determine the processor is not having problems. You can first try all the troubleshooting recommendations having the Intel® Turbo Boost Technology Monitor uninstalled.
For this matter, please make sure the latest BIOS version of your motherboard is installed in order to have loaded the latest micro code available for your processor, for a proper recognition of it.
Also, feel free running the Intel® Processor Identification Utility to see how the processor is being recognized by the system: http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Processors&ProductLine=Processor+Utilities&ProductProduct=Intel%C2%AE+Processor+Identification+Utility&OSVersion=Windows+8*
Furthermore, you may want to run the Intel® Processor Diagnostic Tool to verify the processor’s functionality: http://www.intel.com/support/processors/sb/CS-031726.htm
After the previous, you may proceed installing the Intel® Turbo Boost Technology Monitor: http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=19105&keyword=turbo+boost&DownloadType=Utilities%2c+Tools+and+Examples&lang=eng
