Why Intel Turbo Boost Is Disabled In Windows 7?

post #1 of 5
Thread Starter 
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.

The guy who sold me laptop said that he disable Turbo Boost, however it was enabled in BIOS. Maybe he meant he disable it in OS?

Reinstall or just install the Turbo Boost driver via the Dell support website.

My last dell was like that. After a fresh reload it wouldn't go up to 2.8 from 1.6 and it was driving me bonkers. I installed this driver / software and was greeted by the sidebar widget showing when I was "boosting". smile.gif

DELL does not have such driver / software for my model. How is it called exactly?
