    Hi guys, i'm thinking about undervolting my 540m because it reaches way too high temps (94-95 C after 20 mins of playing and starts throttling). It is not overclocked, there is no dust, i have a cooling pad. I don't feel safe with these temps (i don't know if they are common for this laptop), and i'm really pissed off by gpu throttling every 5 mins.

    I've read that it cools down temps and allows overclocking too, so i would really like to do that.
    I tried with nvidia inspector but anytime i switch the voltage down from .980 to .830 and press apply it gets back to .980.
    I've red i've got to flash gpu BIOS on Grooves guide ( http://forum.notebookreview.com/alienware/269020-grooves-guide-volt-moding-your-gpu-lower-temps.html) (images are down though).
    Is this guide good for RC730?

    I've no experience in this and i would like some advice before trying!

    That is the nVidia 540M GPU I presume, not the Intel 540M CPU.

    I have no knowledge of GPU BIOS hacks. My first route of attack would be to look at the thermal connectivity between CPU / GPU and heatsinks. Often it is a combined system with a thermal pad on the GPU. If this is the case in your RC730 then search this site for threads such as this with fixes such as copper shims.

    Thank you for your reply John, i would loock for copper shims too.
    By the way it seems it's impossible to backup BIOS (with nibitor or gpu z) on samsung rc730 so i can't do undervolting in any case.
    Seems like Samsung locked BIOS writing.
    Someone has solved this issue?
