Lot of Pstates seems to not be used ? (7700k) #399

Hi !

I have a 7700k CPU. Using ssdtprgen, with that args : /ssdtPRGen.sh -target 5 -turbo 4600 -bclk 100 because my CPU is overclocked.

The "problem" is that, even if ssdtprgen show me all the Pstates, MacOS seems to only use 4 of them. 1000, 1300, 4500 and 4600mhz. As you can see here : 7700k

Is that the correct behavior ?

Thanks !

I seem to have this issue with native generator as well. going between these three `CPU P-States [ (8) 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 ] iGPU P-States [ 5 21 ]

CPU P-States [ 8 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 (42) 43 44 45 ] iGPU P-States [ 21 ] CPU P-States [ 8 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 (45) ] iGPU P-States [ 5 21 ]

Yep, exactly the same. I see a lot of numbers, but only 4 states of them are used. It's not really a problem on a desktop, we could be running it at 100% 24h a day but it's a strange behavior.

I actually have slight hangups at times and have been wondering about what is going on with the speedstep
