    1- Download GPU-Z for Monitoring, Check if your temps (max temps while gaming) allow some OC headroom. (e.g., Battlefield 4 MP 64 Players).
    2- DL Nvidia Inspector for OC.
    3- push to +75MHz core/250MHz Memory and test (semi-random safe OC values).
    4- Play a demanding game on CPU+GPU and check your max temps with GPU-Z.

    So I tried GPU-z with BF4 and the temp were quite good I guess, around 60*C to 67*C :)

    SUPER EDIT: BF4 crashes everytime after I tried OCing to +75MHz/250MHz.. sigh :( Is there any other option other than 75/250 or is this the end of my OC journey? haha

    What do you mean? I just change the core and see if its ok without changing the memory?

    Here is my laptop, Lenovo Y410P tho mine is with a GT 750M Nvidia GPU not a GT 755M

    EDIT: So I did only change the core to +75 and the game did not crashed, the temp were the same as before, around 60*c to 67*c. What's next?

    Latest one, 344.75 and I have one small problem now but it does not apply to all, maybe I need to reboot my PC or Idk, but I tried playing other game (BFBC2 and Dragon Age:Inq) and I noticed something after I OC, there's like this small stuttering, it's not going smooth.. but on BF4, it does went well, I dont know why haha but anyways, time to sleep, I'll catch up with you tomorrow, cheers for the help! :)

    limit those to 60 fps and enable vsync by D3D Overrider.
    Lower clocks until rock solid crash-free and the 5MHz less just in case
