Ok, Athos I found how to get the Hyperthreading cores active.
Aparently the extra power is PARKED and used only when needed. I found a small registry tweak which unparks them and now I got activity on ALL 12 cores!!
Here is the tweak:


- 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


So far it does not seem to break anything but the day is young. It seems reversible in case...
