hello. i have an emachines motherboard that is based on the nvidia 6150/430 chipset. i put my old 8800gt in it and installed the drivers and ntune for it. i noticed that when i go to the device settings, it gives me options to adjust the cpu bus, motherboard bus and HT link, ram timings and the usual GPU settings. im wondering that even though this board in the bios does not have any options for overclocking because it is an emachines, could i overclock through the nvidia ntune, and if so would i be risking messing up the board? ive overclocked alot in my time but only with boards that allow it in the bios, and dont know what to expect with a board that doesnt allow it but through a software level. thank you for all your help
