Hi All,
 
WIN7 64 bit, Intel i7, 8 core CPU.  Noticing 4 of my CPU cores are "parked" (1,3,5,7) when I view the Resource Manager.  I've seen the old post on this forum about updating a value in the Registry (which I'd rather avoid) to use all 8 cores - but there's also some free software on-line called "Peak Control Free" that adjusts CPU Core parking.
 
Anyone familiar with this software?
 
Thanks,
Danny V.

which version of sonar ?
you might be seeing an effect of plug in load balancing.

Im not familiar with that software, but I have i7 6 core, in preferences/audio/config file, ThreadSchedulingModel  (4 up from bottom of list) I believe should be set at 2 (or I have it set there), also using Sonar load balancing was causing me issues when I first tried it so havent used it again, I forget exactly, it was like a year ago,  and I didn't need load balancing it as it is always pretty balanced between the 12 cores showings (i.e., with 6 threads).
 
 

If you mean parkcontrol free then yes it does work,  is safe and very simple to use.
 

Thanks for the responses. Yes, I did mean "ParkControlFree."
 
I'm using Sonar Pro 2016.12.  But it's not really a Sonar issue.
 
I notice 4 of my cores (on an 8 core i7) are always parked.
 
Surprisingly, when running SONAR or PT, there is some activity showing on the parked cores.  Not sure why/how...
 
But with SONAR I see peaking on core 1 with the Performance Module set to System Performance.
 
Thought running that ParkControl software might unpark all my cores and stop the peaking on core 1.

Did running park control work.?

I’ve been using ParkControl for 2 years. Definite improvement in spreading out CPU load. Love it. I’m on Win 10/64. YMMV.

Just disable it.  Its very easy
