bro i have over clock my pc but it does not start and hangs so i have to clear my CMOS everytime i clock it..is it because my DDr2 Ram is 667,i set my clock speed to 220fsb and ram to 1:1 other then that my motherbord does not allow to change
i am using MSI 945G chipset (MS-7507)

if ur ram is at a 1:1 then with a 220mhz bus youve got ur RAM running at 440mhz. It should be fine. what board do you have? voltages? etc? also, i remember hearing that this CPU didnt overclock as well as some of its predecessors.
