Yea I've done that before. I tried simply changing the CPU frequency, but when I check in Windows (using Vista) using CPUz it still says its working at 200.9 instead of for example 240.0. I'm wondering is there a setting I have to turn off that locks changes from taking effect?
okay, i'm fairly newb at oc'ing. i've only done it once with my old pc (a athlon xp 3000 single core), which eventually burned out after a year.
i now have this mobo:
