gigabyte overclocking problem

For anyone out there who has a gigabyte motherboard whith intel core2 duo and vista (not sure which thing caused the conflict) do you have any experience with the easy tune device for overclocking cause it caused me some major down time and have uninstalled it i have a feeling it cant deal with dual core cause for a moment before my pc froze i swear i saw two different system speeds on the system page ? had to flash the bios.
