Windows 7 & Core Parking .... a *better* way to Turn It OFF ....
Firstly major props to new forum member sky60234 for the following method. Some of you will recall my previous regedit to turn-off Win 7 Core Parking here:- http://forum.cakewalk.com/fb.ashx?m=1852473 This is now superseded by a much better method. Thanks to sky60234 there is now an easier / non-destructive / fully reversible way to do this - ie: no deletions of .Reg keys needed - only an entry value adjustment. ________________________________________________________ In short, here is the better method from sky60234:- - Go to Regedit - Find this key:- " 0cc5b647-c1df-4637-891a-dec35c318583 " - Within this key, there is a value called: " ValueMax " - This value represents the % number of cores the system will park - the default 100% ie: all Cores are potentially park-able - Change the value from 64 to 0 so the " ValueMin " and " ValueMax " are both zero - You will have to find the key a few times and repeat the process for each time it is found - the number of instances will depend on the number of power profiles in your system [ in my DAW it was only found twice ]
- Do a full shutdown and power-off and cold-re-start
________________________________________________________ I have tested the above on a clean Windows 7 x64 / Clean 8.5.1 install and it works perfectly - all Cores are available at all times and none are ever parked - the result = even CPU loads at all times regardless of loads. As sky60234 noted, the advantage of the above is that nothing at all is being deleted from the Registry - all that is being done is that a value is being adjusted. Again, major thanks and props to sky60234 for this excellent fix. Tom

That's a good tip.
Is that setting in any way related to 'Minimum Processor State"
and "Maximum Processor State" in the" Processor power management"
section of "Advanced Power Settings" in Win 7?

Hi Fret Wizz
No.
The setting in the 1st post of this thread [ and the regedit it " replaces " in the cross-referenced thread ] is solely to disable CPU Core Parking in Win 7 for quad-core DAW's.
It [ and the regedit it " replaces " in the cross-referenced thread] are the only 2 known ways to disable CPU Core Parking in Win 7 for quad-core DAW's.

I guess this doesn't apply to me yet as even though
I'm now wunning Win 7 my PC is a Core 2 Duo.
Building an i5 soon so it'll come in handy then.

Hi rockreid !
Yes it %100 does include your Q9550 - so if/when you go to Windows 7, you will need to make this adjustment.
As riojazz noted it applies to all Windows 7 X64 and X32 installations where the system is using more than 2 physicial CPU's and/or more than 2 "logical" cores - ie: all Intel CPU's that are Quad-Core or higher.
Tom
PS: I assume it also applies to AMD quad-core cpu's but I dont use AMD for my DAW'a any more so I cant be certain, but my expectation would be that AMD quad-core would respond to core-parking exaclty the same as the Intel quad-cores.

Tom, Thanks a lot for the info. And big thanks to sky60234 for providing this simple method. There's another new feature in Win 7 that people may want to avoid as pointed out in this thread: http://forum.cakewalk.com/tm.aspx?m=1858476 Just throwing it out there for those who haven't read it and may not want this in their system.

Or simpler yet just cup the text below and put it into a text file named "disable core parking.reg" then double click the file and answer yes when windows asks of you want to merge this into the registry.
copy the text below this line:

I'm not so sure. I'm running an AMD phenom and in a fit of curiosity I ran sonar for about 45 minutes with the resource monitor running and it never parked a core. I intentionally went totally inactive for over 5 minutes twice and it just never happened. So I'm guessing that either a) AMD processors are not affected, or b) core parking doesn't happen quite so much. ymmv

Can't remeber which thread, but I do remember Noel saying "There was no appreciable difference..." in any of their core park testing. No hiccups, no bumps, nada. Ergo, they were not at all concerned with core parking.
Ergo, I did not remember this until you said, "Maybe Noel can clarify...".
You could probably search "Noel" and "Parking" and find it on the first try. It wasn't more than a month or two ago.

So I tried the change and was able to edit the key like 3 times I believe. I changed the max value from 64 to 0. Exited and then shut down. However when I restart and go the resource monitor I still show cores being parked. I went back to regedit and searched for the key again to double check and the changes are still there correctly made as far as I can see. I have a dell xps 900 i7920. Any ideas what I might be doing wrong or why this fix wouldn't be working.

Did you disable SpeedStep in the BIOS?
Restart your computer and press F2 on boot, which will take you into the BIOS. I think the SpeedStep setting is under "Performance" (or similar wording). Shut it off and see if that helps. Also, make sure that your power setting is set to "High Performance". This can be found in the Control Panel under "Power Options" (change the View to "Small Icons" to make it easier to find).

That is what I was thinking. I'd be surprised if there was any noticeable difference when you disable core parking. The fact that Sonar is always using CPU cycles even when stopped seems to imply the cores would probably not be parked while Sonar is running unless the project was essentially empty. And even if it did park cores, I would be surprised if they could not be un-parked fast enough where they would actually cause a glitch. Basically, do we have any proof that this makes any difference while using Sonar?

Same thing here. One core stays higher than the others in Sonar 8.5.2. Find and change the reg key 2 times on Windows 7 Ultimate 64 bits. The Intel SpeedStep is disable. Any clue ?

Honestly, I don't know why people bother with turning core parking off or overclocking with the Core i7!
Has anyone run into some limitations that require any of this? I think people are still holding on to "old Windows XP optimization tricks" that are pointless nowadays.
Anyway, please correct me if I'm wrong.

Core parking is a problem cause you reach a limit that is not the real limit of the CPU power. Sure, you're right, with i7, it needs huge projects to take the CPU down but there's no reason that each core doesn't work equal.

Firstly major props to new forum member sky60234 for the following method.
Some of you will recall my previous regedit to turn-off Win 7 Core Parking here:- http://forum.cakewalk.com/fb.ashx?m=1852473
This is now superseded by a much better method. Thanks to sky60234 there is now an easier / non-destructive / fully reversible way to do this - ie: no deletions of .Reg keys needed - only an entry value adjustment.
________________________________________________________
In short, here is the better method from sky60234:-
- Go to Regedit
- Find this key:- " 0cc5b647-c1df-4637-891a-dec35c318583 "
- Within this key, there is a value called: " ValueMax "
- This value represents the % number of cores the system will park - the default 100% ie: all Cores are potentially park-able
- Change the value from 64 to 0 so the " ValueMin " and " ValueMax " are both zero
- You will have to find the key a few times and repeat the process for each time it is found - the number of instances will depend on the number of power profiles in your system [ in my DAW it was only found twice ]
- Do a full shutdown and power-off and cold-re-start
________________________________________________________
I have tested the above on a clean Windows 7 x64 / Clean 8.5.1 install and it works perfectly - all Cores are available at all times and none are ever parked - the result = even CPU loads at all times regardless of loads.
As sky60234 noted, the advantage of the above is that nothing at all is being deleted from the Registry - all that is being done is that a value is being adjusted.
Again, major thanks and props to sky60234 for this excellent fix.

Core parking is a problem cause you reach a limit that is not the real limit of the CPU power. Sure, you're right, with i7, it needs huge projects to take the CPU down but there's no reason that each core doesn't work equal.
What makes you think that because all cores are not working equally at any given moment (by that I'm assuming you mean spreading the load equally among all cores), that the computer is not performing at its optimum level? Why must all cores be engaged if it isn't necessary? It might be a waste of resourses. I think the Multi-Core CPUs are designed (by very smart people) to kick in when needed.

As far as one core doesn't reach 100% (and stop Sonar) before others are used, no problem of course.

What we need is a solid instance where core parking is a problem. On the face of it, it does seem unnecessary for a desktop machine. But can anyone show it interferes with Sonar?
