CPU giving 1/3 performance compared to same CPUs Nighthawk: As I mentioned elsewhere, it's not overheated. Fan is clean as a new one and the temperature is 38 C (below normal) and maximum about 50 C (still good for CPU) when used intensively. |

CPU giving 1/3 performance compared to same CPUs Horatio: look at this results. Core Duo T2500 @ 2GHz has a score of 965, calculated from 44 samples (point mouse over the bar). cpubenchmark.net/… Pick any laptop from the sample database provided by the PerformanceTest tool and you'll get ~965 score for Core Duo T2500. I don't think FSB could cause 1/3 performance just in my case, no in case of other guys from the 44 sample list. I think it must be something different. |

CPU giving 1/3 performance compared to same CPUs I don't think it's overheated. Temperature is bellow normal (38 C) and there's no dust or dirt in the fan. What I see as a problem is that everything from BIOS to various tools is reporting cores as 1.0 GHz throttled down to ~ 690 MHz because of multiplier 6x not 12x. If multiplier is raised to 12x, cores are reported as 2.0 GHz but still throttled to ~ 1400 MHz. |

CPU giving 1/3 performance compared to same CPUs I have the latest BIOS. Also tried to boot to linux and got the same results - cores are displayed as 1.00 GHz not 2.00 GHz and benchmark is worse than in WinXP. So it's not a Win/driver/software issue. |

CPU giving 1/3 performance compared to same CPUs Hi Beniamin, I've updated the question. According to RMClock it's throttled down from ~995 MHz to ~695 MHz. I've no idea why the core clock is 1.0 GHz and not 2.0 GHz and what's throttling it down. |

CPU giving 1/3 performance compared to same CPUs I ran a memtest and updated the question. RAM is probably not causing it. |

CPU giving 1/3 performance compared to same CPUs There's a Dell QuickSet software which allows you to set just actions taken when closing the lid, pressing power or suspend buttons and display brightness. Nothing related to CPU throttling. |

CPU giving 1/3 performance compared to same CPUs Laptop is plugged to power, power scheme is set to Home/Office desk (in WinXP). I'm not running any antivirus or other services in the background. (question updated) |
