hello i bought a e5700 3.0ghz and the clock multiplier is stuck on default 6, when i change it and reboot it goes back to 6 all the time does this mean i only have 1.20ghz? i thought the default clock would be 15 when i bought it. was it a waste of money because the cpu is locked? also is there a way to unlock multiplier so i can change it? any help is apprieciated thank you
