    I've OCed the cpu on the bios to 166mhz but it still says @1.20 in the control panel...or is it supposed to be like that?

    do i have to use a program to OC that '@1.20'?

    I'm planning to play FFX on pcsx 2, and i heard it is cpu intensive and needs to at @2.0 at least to play smoothly...

    download cpuz and report what it says under "bus speed". If it's around 166 then it worked.

    that's the spec. the core speed is being reported as 2.8ghz. Looks overclocked.

    Now to take advantage of that OC, make sure you install throttlestop. Otherwise, you'll discover that your computer will actually be slower with the OC because of throttling.

    In principle your settings should be ok. I would set your max turbo limits higher, but that's personal preference. Mine are set to 100/100. Also, go to options and set your "Force TDP/TDC" value to 16 or below (mine is 8).

    turbo limits are the TDP and TDC right? the ones that are on 30/30

    so i should change that to 100/100?

    If the multiplier is bouncing, then you need to adjust the "Force TDP/TDC" value. In my experience, a value of between 6 and 10 is the sweet spot for ensuring a stable multiplier.

    Yes.

    would you consider the multiplier bouncing from x16 to x17 stable?

    also sometimes it drops to x14... pretty sure thats not stable then...
    I have set "Force TDP/TDC" value to 8

    When idle at the desktop or lightly loaded, the average multiplier reported by ThrottleStop should be bouncing all over the place. These CPUs constantly vary the amount of turbo boost which constantly changes the multiplier that the CPU is using.

    When you fully load both cores of these CPUs with a testing program like Prime95 or a benchmark program like wPrime, then you will see the average multiplier settle down.

    When 1 core is awake and 1 core is asleep, the multiplier goes a lot higher. When the second core wakes up, the maximum multiplier immediately decreases. This can be happening hundreds of times a second when these CPUs are lightly loaded and individual threads are constantly entering and exiting various sleep states like C3 and C6.

    Head to the M11x-R2 Supercharge thread if you want to learn some more about maximizing the performance of these low power CPUs. If you're too busy to read then just read the first post and follow those settings and your laptop will be running a lot faster compared to how Dell ships these.
