Why is Intel Turbo Boost Not Working On My Laptop? (Continued)
Dell Latitude E6420 is my laptop with Windows 7 Enterprise. Turbo Boost is enabled in BIOS but is disabled in OS according to AIDA64. I managed to install Intel Turbo Boost Monitor but it says that Turbo Boost is not enabled. Although I still see standard speed but I also see "Energy Saver" appears when CPU runs at less than standard speed.
What is interesting is that Turbo Boost gets enabled in OS only when SpeedStep is enabled as well in BIOS. This slows down CPU to ~700Mhz and stays there no matter what. Enabling\Disabling C-State did not do anything and there is no multiplier.
Intel Chipset Utility is the latest version and I did not find any Turbo Boost driver, nor any service in Administration.
I have found drivers package for my model here. The problem is that i do not know what is responsible for Turbo Boost.
