    added undervolted version for the gt525m card
    2d profile: 0.83v
    3d profile: 0.85v

    I'm testing/using it right now :)
    DL link and info at the first post ^_^

    +1

    2D PROFILE desired voltage: 0.83v
    3D PROFILE desired voltage: 0.98v
    Card Model: GT540M

    Keep up the good work! :)

    Cheers

    on the way ^_^

    however take in mind I cant test the ones for the 540m, so tell me if there are any issue.

    also, when I opened the stock 540m Vbios from the A07 dell updte, nbitor reports it seems to be running 0.83v and 0.98v already

    however I also noticed I can set also 1V (540m only) (also noticed 0.95v is missing from the 540m table)

    are you interested on the 1V on the 3D profile?, or you want I try to set the one you requested (even it seems to be already running at the vbios?)

    I'll be a beta tester and try the 1V for 3D. - seems odd that the voltage settings are different when both the 525 & 540 are essentially the same chip I believe.

    The 540 has higher clocks, so has a higher power requirement.

    jsut installed the undervolted one, didn't destroy the world so that's a plus :)
    testing will commence
    Edit: not an insane difference, but furmark does seem to heat up a little slower. no word on battery life yet. fps seems unaffected

    0.83v , 1V version is out for the GT540m, as allways DL from the first post.
    need feedback from GT540m users!! ^_^

    well, using undervolted bios usually get the temperature as the most noticiable event.
    reducing the voltage may affects the battery too, but minimal, battery life depends on a lot of things, most significant ones are gpu ussage, lcd brigtress, cpu ussage, wireless.... etc, if you turn off unnecesary devices, uses a low consumition windows plan, low brightress etc... , you will get longer battery time per session.

    as for the fps, I didnt modified the clocks cause every user chip will handle the overclock different,I just modified the voltages, so the fps should be the same, if you want more fps, do what I said, with the moded bios installed , download msi afterburner or any other overclocking software, and adjust the GPU core at the highest STABLE clocks, testing overclocking require patience and a lot of tests, if a configuration crashes the card, try again by lowering 10 mhz the core until you get a stable configuration, overclocking the memory too much can also cause artifacts or crashes.

    I'm aware there are no clock changes. I'm just saying that the lowered voltages do not seem to effect fps
