sorry for not explaining clearly. It always(idle+load) showed 2.33Ghz in cpu-z and in bios(the cpu freq in sys info and cell menu). only in the properties tab in MY COMPUTER, it showed 3.0Ghz,3.0GHz. But after enabling speedstep, it idles at 2 GHz, and goes upto 3 GHz under load.
One out-of-topic question: how can i overclock in the xfx 750i board? i'm not getting any options in bios or nvidia control panel? i heard that i need some kind of jumper. Can anyone please explain what i've to do?
