- 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
It is a power saving feature. That having been said, on a laptop there's no reason at all to turn off speedstep or core parking. They make almost no difference in performance, but they make a huge difference in power consumption.
I would still like to know why the OP believes that it is necessary to turn off core parking.
