    I have a dell xps 1645 and i have noticed that some games like EAs FIFA 2010 only work on 1 core. Is there any way to use other cores so the game works smoother.

    try updating to the latest patch or try setting core affinity to max

    why did you open two threads for this?

    Depends on how the code was written for the game. Some games will only use dual core while other use quad, and older ones use a single core.

    How are you measuring the fact that the game is using only one core?

    On a Core i7 mobile CPU, it's to your advantage when a program spends most of its time running on a single core. This allows the other 3 cores to spend more time in the C3/C6 sleep state so the one core that is doing all of the work is allowed to spend as much time as possible using the highest multiplier.

    That's how the mobile Core i CPUs are designed to work and they work great so don't try to out smart them. Come to think of it, the recent Core 2 mobile CPUs that support Intel Dynamic Acceleration (IDA) work the same way. They run at a faster speed when one core is awake working while the second core is asleep.

    Run a ThrottleStop log file and you should see a nice high multiplier when playing this game.

    It's very rarely to your advantage to be using only one core. The whole point of splitting things onto multiple cores is for parallel processing. What before needed to be done sequentially, one after the other, can now be run in parallel. It's true that, because of the way TurboBoost changes the multiplier, you would get higher performance on single cores on an i7 than a similarly clocked/cached processor without TurboBoost, but it will still not be as good as running on multiple cores. On something without TurboBoost, you could see a straight linear improvement with multiple cores (i.e., 2 cores doubles speed, 4 coures quadruples, etc.) on embarrassingly parallel processes. You won't see something like that with TurboBoost, but you will still see improvement with increased cores.
