Yes it is.CrispyXUK said:Is this true even when using a DSDT?
Well if I am not completely wrong, Speedstep requires ACPI do be enabled in Bios. Actually, what this text of yours is saying is that your CPU does not support ACPI??mcbyte_it said:MacMan said:Yes, this is recommended for almost every motherboard.

Is this true even with:

is it enough, or I need to add the specific c2, c3 etc. and described?
shibirian said:Each Intel CPU runs with a multiplier, for example, my Q6600 has a max. multiplier of 9, so 9x333 = 3Ghz.
Minimum multiplier is 6.
So with Speedstep enabled when the CPU idles the minimum multiplier is applied, so 6x333 = 2Ghz.
This saves energy and heat...overclockers don't like that much, because it gets in their way of reaching total-uber-clocks.
All in all, if you value your energy bill it is a good idea to enable it (also cools down your system a bit).

Honestly saying I also have no idea if you need to alter something in a DSDT to activate ACPI in OSX, so dunno...

My problem could be that my DSDT doesn't have the _PR scope, no processors define there
I tried adding them manually, but without a correct SSDT I was never able to generate C & P states, in a couple of occasions the computer rebooted immediately after loading the ssdt...

A nice build also from this guy here

He does not mention if he was able to add C States, lo. -.-
