Ok, try disabling it then. I've not used a AMD motherboard in a while but it should be called something like Cool 'n Quiet in the BIOS.
Edit: Yes. Within BIOS go to the Advanced Tab and then CPU Configuration and then disable "Cool 'n' Quiet". See if that sorts it.
You could go into windows power management and change "min processor %" or something like that to 100%![]()
Cool 'n' Quiet was disabled.
No problem.
@Speed, Better to turn it off at the source, but easier to turn it off and on in windows. Especially if your PC runs hot and don't want it running at max frequency all the time. Save the environment or your energy bills![]()
Right I think I may have solved it...
I've turned on CPU Load-line calibration and it hasn't fluctuated yet so no lag.
Edit**
Spoke too soon :'(
Remove the overclock completely, put it back to defaults etc.
