Us mere mortals nope. Check out Pike's blog http://pikeralpha.wordpress.com/

If you manage to crack it please report back and share the secret.

After some fiddling I managed to get one additional CPU P-State : 8 17 35 36 37 38 39 on my Z87X-UD3H with i7 4470k.

A combination of things : smbios,ssdt, adding frequencyvectors to plist. The pieces to the puzzle are to be found in the link I posted.

I just haven't put them into the right order yet. Right now I'm stuck and I don't want to bother Pike with this. He has other things to deal with.

I only hope that I'm not the only one puzzling... :)

If you want to use the old PM you can edit your ssdt to use the AppleIntelCPUPowermanagement instead of Xnu CPU PowerManagement.

Kyrten did you already have more P-states for your board? I'm just stuck at only 8 35 36 37 38 39 on my Z87-UD5-TH.

Nope. There's some interesting stuff to read on the last couple of pages in this thread http://www.insanelym...kintosh/page-10. About using Clover and letting it generate the states and using a MP3.1 smbios but it doesn't work for me.
