    @Johnksss@iBUYPOWER could you maybe work with svl7 to make another low voltage BIOS? I use your vBIOS for the 970M and it is well done and undervolted to 0.95V, without power throttle. if you could do one for the 980M at 0.9870V or 0.9750V that would be swell.

    Haven't worked with that stuff in quite some time.

    Brother @Johnksss@iBUYPOWER the magic never dies :D ... I used your work on the 880m and 980m and it never let me down. I am sure you can do it.

    A vBIOS like that would not be stable for too many people. (If tested with throttle, they may appear stable but they crash the moment it actually keeps those clocks under shifting loads). Even 1v is already too low for some 980M samples. Also over time, as they age and degrade, the voltage would need to upped once again (RL result of 9 months 0.9xv testing on a 980M).

    I still think that it is better to start at a lower voltage and increase as needed since we can't undervolt on the fly, but we can overvolt. Just my 2 cents.

    I also have a 840m and would like to know how you undervolted yours.
    Did you used the voltage sliders or the boost table?

    how far could a 970m be underclocked in your opinion??

    Gonna try later/tomorrow and ill keep you guys updated ;)

    I know every system is different but it could be good to have an idea of how much we could undervolt approximately

    I run the 980m @1.006V for stock clocks ... I am pretty sure a good AISC 970m chip (70+ % ASIC) can do 0.95V on stock clocks.

    I used the boost table, just increase the max freq, that is the one that draw 1.131v
    then limit the max boost limit in the first tab
