    Twin Turbo Mode lowering FPS?

    So far in the games I have tested, having Twin Turbo Mode on actually lowers FPS by around 4. In Left 4 Dead 2, with VSync on, I get 60 FPS. However, when I turn on Twin Turbo mode I can only get 56 FPS. Also in GTA IV and Fallout 3 it lowers my FPS by 4 also when it is turned on. Is this normal? Does it happen to anyone else?

    Basically, as all cores get saturated, the multipliers decrease. For most things, Twin Turbo is a gimmick.

    I've done similar test/benchmarks using 3Dmark06 and vantage, and it does seem that turning on twin turbo lowers the CPU score. With that said, I've always had twin turbo off

    really? for me I get higher scores with twin turbo. I can't really say about game performance since I don't really record fps but the only thing that's different in game is that the CPU gets like 5 degrees warmer with twin turbo on during gaming.
    I just do manual OC now using setfsb and the temps are lower at load

    How high can you OC with setfsb?
    I've heard conflicting reports that it does help and doesn't help?
    If possible can you run 3DMARK06 stock and with setfsb?
    A laptop purchase depends on it. ;)

    I can only OC to 1.75 ghz, but some people report OCing a lot higher.

    As for 3dmark06
    all stock clocks: 12450
    twin turbo enabled: 12792
    manual CPU OC with setfsb: 13057
    setfsb OC and GPU OC to 785/1300: 14003

    hope that helps!

    Ok, but why would this happen? When I have a game open with CPU-Z Twin Turbo Mode is increasing my clock speed by about 100 MHz.

    Because you are not fully utilizing all four cores.

    read the wiki article on core i5 and i7. The CPU will "turn off" cores and ramp other ones up for single threaded games. If you have a game that supports 4 cores it will probably use that, versus running on 2 or 3 at a higher usage.
