    nope, there was a topic at the bios mods forums, but it seems inactive right now, and I dont have the skills to accomplish that alone :/

    @utmmyak
    :) thank you

    well, 0.85v/0.95v are already the default values for 525m at the official bios.
    so modding it will make no changes at all :D

    do you want a 0.85v/0.98v for the 525m A10 instead?

    Well this might be my last post from this laptop :D , i have the gt540 2GB GPU in my system , i think i was lucky because it overclocks very well and runs cool , but after i pass the 800 MHz mark the performance gains seem to be very small , i believe if i increase the voltage i can not just run higher frequenci but get better performance gains too , i am runing the 0,83V/1V version and i think i am the first one running 900 MHz on the core !!!
    :biggrin:
    All seems OK , but the hard test is just commin .

    I am off to play some games , if you not hear from me by tomorow night , that means the machine is dead , ( feeling bit mad tonight ) .

    I will add you to the first post :)

    900 mhz is crazy!

    if it run stable you may be the one with highest OC ever for this card :D

    well done :)

    anyway put an eye on the temps , 1V can give high temps ^^
