Hi [USER=4875]@np44[/USER], 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 and x25 for single core.


By the way the motherboard is Asus P6X58D-E and I am using MacPro5,1 smbios with -no_compat_check. I tried MacPro6,1 also but it doesn't make any different.
