amd cool & quiet makes voltages unstable

Hi everyone, first off I just want thank major geeks users for the quick responses and the commitment to help others. It takes considerable effort to get this number of posts and thanks. :wave

Anyways, my problem is that when I enable amd's cool and quiet in my bios, the voltage of my cpu fluctuates between 1.0-1.4. Basically whenever I turn on utube or some music, the fluctuations occur, but when sitting idly, the voltage is at a stable 1.0ish volts. Should I enable cool and quiet to knock off about 4 degrees at idle (39-43C) or disable?

 

I think you should leave it on shouldn't effect you. Is this a desktop or laptop?

I think you should disable if it starts causing system instability like crashing locking up etc.

 

+1 on that.

I have an Asus MB too, I have the cool and quiet enabled, and I too saw fluctuations while my CPU voltage was set to auto, but now when I set a specific CPU voltage, everything was stable, voltage wise.

As per the above, if you don't have any instability problems, then just keep as is.

 

You have to remember that the function of Cool n Quiet is to keep temps AND power consumption lower when the cpu is idle or running less intensive tasks. So if you do have the voltage set to auto it will fluctuate a little. Setting the cpu voltage to fixed stops that but kinda defeats having CnC on for cpu purposes, it will still change the fan speed.

this is a desktop, amd II phenom X4 965. So, I assume the fluctuations are not damaging? Hmm, ok Id rather the cpu be cool too. I'll post some screenies

 

added a scrennie of the speedfan graph

 

Although there are some big fluctuations, as long as you have no stability problems, i wouldn't worry.
