    Thanks for not giving me any details about your laptop or GPU you wish to undervolt.

    valid argument. Sager 8662 gpu 260m gtx

    unnecessary info: stock, but 500 gb hdd, 4gb ram.

    Have already undervolted the cpu can underclock the gpu with riva tuner.

    Okay, the GTX 260M. You can safely use these clocks and voltages.

    3D application: 550/1375/800 @ 0.95v
    3D desktop: 383/767/300 @ 0.85v
    2D desktop: 275/550/300 @ 0.8v
    Idle: 200/400/100 @ 0.75v.

    These are guaranteed to work, but it isn't the lowest undervolt. You can find out on your own if lowering each level, one at a time of course, by 0.5v will still remain stable not. Always use Furmark with ATITool in parallel, or OCCT to gauge stability at higher temperatures.

    You may also incorporate an underclock as well to drop temps and increase battery life even further. These are also guaranteed to work.

    3D application: 500/1250/800 @ 0.95v
    3D desktop: 383/767/300 @ 0.85v
    2D desktop: 275/550/300 @ 0.8v
    Idle: 160/320/80 @ 0.75v.

    I use NiBiTor and nvFlash to apply the clocks and voltages. I still use Furmark and ATITool, but I've been using OCCT to check for artifacts and stability lately since I'm too lazy to open two programs instead of only one, haha.
