Thanks for replying sir, i tried so many methods to reach this target, but there are always something that prevent me to unlock overclocking. I sended you my bios, but i need to inform you that i already unlocked the hidden settings in system Bios with help of AMIBCP programm and flashed it with AFUDOS version 5.01. However, i cannot find anything related to nvidia graphic card, but found a plenty of setting related to integrated intel video card, where there is even overclocking support for it, but not for GTX 850m. What a strange situation:62: By the way, i noticed that you use Russian e-mail, are you from Russia? You dont need to answer this question, it's just my curiosity)
