Just do it because it's extremely easy to do and it's not time-consuming in the least bit. It's literally the easiest thing that you could possibly do here. Why haven't you done it yet?
So, as I posted before:
"Just go ahead and disable C3 and C6 right now. Why wait? We need to experiment with everything here.
If this doesn't make any difference, then disable SpeedStep (leave C3 and C6 disabled). If that doesn't make any difference, then disable C1E - leaving SpeedStep, C3 and C6 disabled.
If that doesn't make any difference, then do whatever you need to do in order to make sure the voltage doesn't go down while idling or under light loads. I think the problem is that the CPU isn't getting enough power in light-loading and idling situations. Think about it..."
There's no harm in experimenting with these settings. If this is the culprit, then think of the money you'll avoid wasting by not having an electrician come to your house.
C-States were off by default, so I have turned them on and will test now
