Windows 7: CPU Core parking/performance concerns

Strangely, I don't have the option in that screenshot. All my Processor Power Management tab lists is "System Cooling Policy". I have no option to see other available options.

I have a setting for the C6 power state in BIOS. I'm going to fiddle with that and see what comes of it.

I found some advice from Microsoft and it states:

If UAC is disabled, the "Change settings that are currently unavailable" option will not be available.

I don't know if this applies in your case but you could check anyway.

I suppose that if UAC is disabled you could just enable it on a temporary basis to get access to the settings.

Additional Info

There's some interesting information on Core Parking in an archived article from Tweakhound. I've posted the archived link as the article has been removed from the website!

If uac is disabled you would get access to all settings immediately. Even when I elevate uac to show all options I still do not have that option.

Well, after some diddling around, I realized that there were two hotfixes and I hadn't applied the first one. I applied the first one, and then the second, and presto! Core unparking! My rig runs a tiny bit hotter at idle now, but it's only a degree or so.

I haven't run anything taxing on the rig to see if it's a little better performance-wise, but I suspect that I'll never notice the difference, but looking at my core graphs, it's using all 8 cores at times. It never did that before, except when I was running Prime95.

And I still have no power state management in my power plan...

Yes I know you have. I don't want to clock mine as high as you but just got the 8320 to 4ghz in the bios on the Sabertooth with no trouble whatsoever. I am using a Hyper 212 with push pull fans in both of them.

Power Plan?

Well here's a thought - it might be completely wrong though! I see that you have an ASUS machine. My ASUS machine came pre-installed with a lot of ASUS extras, one of these was ASUS Power Management Utility. I removed all of the extra stuff by downloading a windows 7 ISO and doing a clean install so I can't check if the ASUS Power Management Utility over-rides the default windows power management options but I suspect that it might!

Nah. I never installed any of ASUS's bloatware. I have a totally clean install as per the tutorial here. The one gregrocker always links to.
