Hello, I want to overclock my lenovo ideapad y560 laptop. i want to overclock its gpu, i want its ram to run at 1333 mhz. This has 4GB DDR3 1333 dual channel RAM but it runs at 1066 mhz as core i5 supports 1066 mhz max. I cannot overclock using ati tool, it's showing abnormal clock speeds and the sliders cannot be moved up they can only be moved down.
