It is impossible to have a speed step.

Depends a bit on your hardware... Here is what I've found on my Sandy Bridge systems (both desktop and laptop):

- Need /Extra/ssdt.aml (generate one using MaciASL)
- remove /S/L/E/NullCPUPowerManagement.kext
- need Processor directives in DSDT in Scope (_PR) section, can be added with following patch, if you don't already have them
(this patch is part of my dh67xx patches: https://github.com/RehabMan/Intel-DH67XX-DSDT-Patch)

into definitionblock code_regex . insert
begin
    Scope (_PR)\n
    {\n
        Processor (CPU0, 0x00, 0x00000410, 0x06) {}\n
        Processor (CPU1, 0x01, 0x00000410, 0x06) {}\n
        Processor (CPU2, 0x02, 0x00000410, 0x06) {}\n
        Processor (CPU3, 0x03, 0x00000410, 0x06) {}\n
        Processor (CPU4, 0x04, 0x00000410, 0x06) {}\n
        Processor (CPU5, 0x05, 0x00000410, 0x06) {}\n
        Processor (CPU6, 0x06, 0x00000410, 0x06) {}\n
        Processor (CPU7, 0x07, 0x00000410, 0x06) {}\n
    }\n
end;

- Need to be using proper System Definition. I use MacBookPro8,2 on my laptop and MacMini5,1 on my desktop
- Need either patched BIOS (not available for Intel boards) or patched AppleIntelCPUPowerManagement.kext to avoid BIOS lock placed on CPU MSRs. You can get this patched kext from latest Multibeast
- DropSSDT=Yes, GeneratePStates=No, GenerateCStates=No

- Need either patched BIOS....

That's essential for Asus Boards to get working speedstep !!!
