Re-enabling speedstep and C1E after finding stable overclock.

Is it standard practice to do this?

I've had both of them disabled for a couple of months since finding a stable Core voltage, but would like to know if people leave them off or leave them on.

I have turned mine off.

Ok but what about when your machine is idle.

Say for example if I had a steam game downloading while I was at work.

The only viable option other than doing this is do have two bios profiles and switch between the two.

Well turn them on and see if you find any instability. In my experience, C-States can cause instability during idle depending on your settings but SpeedStep doesn't.

I found when I did have speedstep enabled the speed difference was minimal and energy saving again I believe would be extremely minimal.

i run my AMD with CnQ enabled, helps keep the temps down when it's just idling or being used for menial tasks

I take it cnq is the amd equivalent of speedstep?

yup, cool and quiet, makes quite a difference between idling at 30c or idling at 40+

I turned them back on after overclocking my Q6600 to 3Ghz.

There is a very small difference in performance, which I guess could be put down to normal variation.
