thanks for your help but i have been thinking about it and i dont want to change the bios, just bought this notebook i got it running at 1100/2600 right now with a nvidiainspector bat file overclock.bat idle.bat this is what i've been using now. before gaming i run the overclock.bat and idle.bat is underclocking with low voltage ~0,97 but the idle.bat doesnt work the way i like it to. i want it to return nvidia optimus(use integrated intel gpu for surfing/video etc), but i cant reset the pstate, doesnt work with nvidiainspector. i hope you know what i mean. maybe you have another idea or command i could use. isnt overclocking with nvidiainspector/afterburner much safer in case of warranty? regards - - - Updated - - - i cant edit my post before.. just wanted to add that if i reboot my system it will return to the "Nvidia Optimus", properly using the integrated intel cpu until i play games, then ill start my overclock.bat and i can only get back to optimus via rebooting
