    How to force maximum clock speed on an i7?

    I have this unusual problem where when I play a game, the first few minutes/seconds the game runs perfect since my CPU is on max clock, and then after some play time FPS drops like crazy and stays this way (due to my CPU just not recognizing I'm playing a game or something...as a result it doesn't go to max clock speeds). And yes, I have the power management settings all on "high performance". So I've resulted to trying to find a way to force my i7 to max clock speeds. Is there any program that does this?

    Rig:

    Sager/Clevo MALIBAL P150HMx
    Intel Core i7-2720QM
    GTX 580m

    In the 'high performance profile' check the processor state settings in the actual profile. Change the minimum processor state to '100' and maximum processor state to '100' as well. I think the minimum on the default profile is 50, that should force your CPU to be at max clocks all the time as long as it doesnt get too hot.

    If set to maximum performance the CPU should run at the speed the program tells it to.
    If it clocks down it might be throttling due to high temps, if not you can always use throttlestop to keep the processor running at max clocks.
    Sometimes it also helps to disable speedstep.

    Some BIOS allow you to disable throttling or SpeedStep (CPU EIST function). Otherwise, if you are experiencing throttling, that is, you can try ThrottleStop as nakednakedguy suggested.

    Check your CPU temperatures, for all we know you might be experiencing thermal throttling.

    My minimum is already at 100%.

    I have throttlestop, but what are the specific settings I have to adjust in throttlestop to force max clock speeds with a i7-2720QM??

    It's designed to simply prevent throttling. If you want it constantly OC'ed (which is what Turbo Boost does on demand), you can try using t his version of ThrottleStop. It's suppose to enable Turbo Boost in conjunction with nVidia GPUs, at least on the W110ER and W150ER models. You're welcome to try it and see.

    thanks, I have been using that-- but still to no avail. Though anyone know why I might be having this problem??

    When I first got my notebook everything ran fine, SC2 was running at like ~60fps. Then recently my my games have horrible performance after ~1min of gameplay. It's almost as if my CPU doesn't detect I'm playing a game and doesn't go max load. I recently updated my BIOS and updated my OS lately, could that be the problem?

    How much throttling are we talking? I mean also what games? Other than a very serious downclock if GPU is the main gameplay component how much and why is the CPU having such a dramatic affect on gameplay?

    I suspect thermal issues as others have suggested to rule out. Also could the issue also be GPU related?

    Edit: After a reread sure BIOS and OS could be related issue. But do rule out thermal.

    Wait, I already saw a prevent turbo boost in my BIOS. Why not just enable it there? Also, why would you want 100% all the time? Its seems highly inefficient; it would also defeat the purpose.

    It's possible the BIOS update may be causing it if you weren't experiencing it before, but you may want to double check your temperatures. Typically throttling occurs only during system idle to conserve battery, or when a certain threshold is reached to prevent heat damage to the chip.
