Hi, if I try to read out frequences, i will get following mesage:

imac:~ Jan$ sysctl kern.cputhrottle_freqs
second level name cputhrottle_freqs in kern.cputhrottle_freqs is invalid

What does this mean? Using 10.5.5 with Vanilla Kernel.

It means the kext was not able to load.

Try to load the kext manually: sudo kextload /System/Library/Extensions/IntelEnhancedSpeedStep.kext
And then check the messages: sudo dmesg | grep Speed

If you get any WARN messages or similar, turn on DebugMessages flag in the kext's info.plist and try loading it again so it gives more detailed output.

Also check whether your CPU actually supports speedstep: sysctl hw | grep EST
If it doesn't print anything, your cpu doesn't support speedstep.

I have the same problem as yan kun, but my CPU is a Q6600, which does support SpeedStep.
After loading it by hand and doing "sudo dmesg | grep Speed"; I get "There was an error while getting PState array from ACPI. Please create your P-State table manually." many times the same Warning (It's version 1.4.0)

There is no overclocking going on, Ci1 and other Bios things are enables, as should for speedstep.
When doing "sysctl hw | grep EST" it prints nothing.

Will try activating the DebugMessages flag and post back.

And mercurysquad, don't bother about me, you certainly have better things to do, just if you or someone have an idea.

Comming back with DebugMessages.

So after turning debugmessages on and reinstalling, it seems to load at startup.
sysctl hw | grep EST still don't give anything..

Here is the full output from sudo dmesg | grep Speed

Thank you for your attention, and don't worry about it, I can also try again in some months.
It's just that it would be nice to save a few watts.

Cannot be...

After "sudo dmesg | grep Speed" i only get:

IntelEnhancedSpeedStep: INFO Initializing version 1.4.0 © Prashant Vaibhav <mercurysquad@yahoo.com>
IntelEnhancedSpeedStep: INFO Using 4 PStates.


And after "sysctl hw | grep EST":

Nothing!


But i have an Speedstep CPU and your kext seems to work because the fan is slower/more quiet when not loaded high......

Any other way to read out the current speed of the cpu?

1) Edit the Info.plist inside the kext and set DebugMessages to true so that you get more output than just those 2 lines. Don't forget to sudo touch /System/Library/Extensions after editing the plist.

2) It is sysctl machdep | grep EST -- NOT hw

bash-3.2# sysctl machdep | grep EST
machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM SSE3 MON DSCPL EST TM2 SSSE3 CX16 TPR PDCM

Any other idea?? :-D


PS: Yes, i forgot the DebugMessages...:angel:
