    Hi,

    Is it possible to have more than 1.35 volt with msi afterburner? At 1.35 volt my max stable is 1075 MHz, at 1.375 is 1100MHz...

    I have watercooling.

    No, that's a software safety guardband limit defined by MSI and you cannot tweak/bypass it unless MSI decide to publish new version of Afterburner with extended limits.

    Try to close Afterburner, open your profile file with notepad (VEN_1002&DEV_9460&SUBSYS_80301462&REV_00&BUS_1&DE V _0&FN_0.cfg stored into .\Profiles subfolder into application folder), and add the following text to it:

    [Settings]
    VT1165_Defaults = 18 50 ( max=1,450v )

    Clic "reset" automatick increase voltage.

    hmm,

    [Settings]
    VT1165_Defaults = 18 49 ( max=1,365v )

    1,40 and 1,425 not possible (bug) :3eyes:

    For automatic reset at windows startup need a script bat or exe :nerd:

    For benchmarck extreme (cascade/ln2):
    [Settings]
    VT1165_Defaults = 18 51 ( max=1,465v )

    [Settings]
    VT1165_Defaults = 18 52 ( max=1,475v )

    [Settings]
    VT1165_Defaults = 18 55 ( max=1,50v )

    [Settings]
    VT1165_Defaults = 18 58 ( max=1,55v )

    [Settings]
    VT1165_Defaults = 18 60 ( max=1,65v )

    esemple->
    [​IMG]



    @topcaser Downvolt (default 1,0v)
    [Settings]
    VT1165_Defaults = 18 25 (min 0,900v)

    [Settings]
    VT1165_Defaults = 18 20 (min 0,850v) (this is limit my vga, others Crash..)


    Ps: my not responsabil.

    Lory.Hacker,

    is it possible to set voltage for each profile?

    I would think using that workaround would be very dangerous. What if you set the wrong one and you try to "reset" it?

    No it doesnt work and 1.35V is already the maximum the chip supports anyway.

    Not exactly. The programmable voltage goes upto 1.35V, but it's isn't hard to lie to the controller with a pull-down or trim pot on the feedback or regulation circuitry.

    Assuming the percentage boost isn't too much for the cooler to handle, like +0.1V, one could reduce all the video BIOS voltages to -0.1V, and use AfterBurner to attempt 1.35V or 1.45V actual.
