    I want my mobile CPU's clock speed to reach 4.0 GHz or get close to it, but spending 1k solely on CPU(3920XM) seems to be a huge waste. I did some research about 3740QM which has far more reasonable price than 3920XM, and people say it can overclock up to 3.9 GHz. Does anyone know if 3740QM is unlocked, and if it is not how do I do it?

    Also would like a link to thread about 3740/3840QM OC if there is any.

    well
    i have a 3720QM
    i overclocked it to about 4Ghz (see sign)
    i used the intel extreme tuning utility
    just make sure that in Bios>performance options>overclocking- is enabled

    just be sure that overclocking can be very dangerous and harmful (to hardware and user) if done wrong

    Happy overclocking!

    I dont believe its dangerous, becuase the intel cpu's are limited to 55watt for a little time then going back to 45watts and then it will find its max watts.

    So whatever you make, 4,1ghz, 3,5, 4,5 you will always have this limit of TPD

    How do you get it up to 4 ghz? I know how to enable the over clock feature in the bios... But after that then what?

    Just set up your BIOS like this, and it'll be overclocked.

    Yeah it's relatively safe. Using the intel XTU just remember to stress test.

    Mine currently goes to 4.1 GHZ when only one core is active.

    It's the exact same procedure... You could maybe try to go 100 MHz higher first, see if it's stable, then another 100 MHz and so on. But the procedure for the 3740QM described in this thread also applies to 3840QM.
