Which section are you looking under. In the left column, either under the motherboard or cpu there should be something that says overclocking, click that, then find the cpu in the right side. It should say the original speed then what it is over clocked to. If its still 2.66 in everest and CPUZ, got back into your the BIOS and check the settings (make sure you did save and exit right).
Again I don't have the program in front of me right now cause I'm not at my pc, but just go down the tabs on the left wide (expand the listing) and you'll find the sensor and overclock. Its in one of the top ones.
