Also, only MacPro5,1 allows speed stepping to x22; if using MacPro6,1, it will stuck at x12 forever.

Interesting, I tried MaciASL -> New from ACPI -> SSDT, here're the outcome: Without custom SSDT being used, it has the same content as SSDT-0-CpuPm.aml generated by Clover. However, if SSDT-x0_0-P001Ist.aml is used, MaciASL -> New from ACPI -> SSDT does showing all ratio including those x24...

Hi @np44, here it is. I actually checked inside using MaciASL, the file SSDT-x0_0-P001Ist.aml seems to have 12 states, from x12 to x23 ratio. However, I am getting only x12 and x22 in the reality, anything in between just ineffective. In theory, X5670 should have turbo boosted x24 all core...

Yes I got that ssdtPRGen link but it isn't work. I just tried Clover, F4 generate 3 SSDT files (SSDT-0-CpuPm.aml, SSDT-x0_0-P001Ist.aml and SSDT-x0_1-P001Cst), which one should be used? I tried SSDT-0-CpuPm.aml, SSDT-x0_0-P001Ist.aml but still giving me two states only, which is base clock and...

Hi @np44, thanks a lot for this very informative guide! I am on the same platform (X58 and X5670 cpu), Big Sur works OK with OC 0.7 but hopefully I can have your help making it better. 1. CPU PM: how do you generate this SSDT using Clover? ssdtPRGen doesn't for me either. Now I have two states...
