    Hi everyone,

    I own an old 2006 macbook. Windows 10 (32bits) is running on. I have an issue with the CPU, intel T7400. The processor is running 1Ghz per core max instead of 2.1Ghz.

    What I did for the moment :

    - first installation I use Windows Update to find drivers. After I use Apple drivers through Bootcamp 4 and after 5.
    - I reinstalled W10 again with Apple driver (through Bootcamp 4). Everything is working nice, keyboard, sound, webcam, trackpad, ...
    - I scanned for new driver using Windows Update, Touslesdrivers, driverbooster, Intel driver assistant, ....
    - I installed Intel XTU (CPU not supported)
    - I installed ThrottleStop (CPU not supported) to have some informations
    - I did lot of others things, I don't remember all.


    This isn't thermal control because even when my PC is cold the CPU is runing only 1Ghz. Max temp is 50°C.
    I try to reinstall MacOSX 10.6. The CPU is running 2.1Ghz.

    This isn't a power limit because the voltage is 0.9V instead of 1.2V

    I checked those information with HWinfo.

    Windows reconizes my CPU like 2.1Ghz each core.

    The EFI is the last version (mac Version MB21.00A5.B07 (EFI 1.1)). The EFI is locked so I can't go in like other laptop with UEFI, it's sad.

    If someone has an idea, that can help me.

    Bye

    Have you tried installing Windows 7? It would work a lot better on that machine than 10.

    No I didn't. It's a solution to try.
