Speedstep issues

[BobOki]

I am trying to disable speedstep and after reading some different threads I install the ACPICPUThrottle.kext, that works without a problem, however I get this:

boboki$ sysctl -w kern.cputhrottle_cpufreq=1700

second level name cputhrottle_cpufreq in kern.cputhrottle_cpufreq is invalid

 

Any ideas guys?

Are you loading the kext manually in your /etc/rc file? I had to load the kext myself before it would register the sysctl. Add this to your rc file before the sysctl -w line:

 

kextload /System/Library/Extensions/ACPICPUThrottle.kext

 

replace "/System/Library/Extensions/ACPICPUThrottle.kext" with the path to where you installed the kext. I put mine in my Extensions folder so thats what I did. Hope that helps. Peace

Thanks for the quick response BH!

I do not have it in my rc yet, currently I am manually loading it until I get it to work.

Below are my results:

bobokimaclaptop:~ root# kextload /System/Library/Extensions/ACPICPUThrottle.kext

kextload: /System/Library/Extensions/ACPICPUThrottle.kext loaded successfully

bobokimaclaptop:~ root# sysctl -w kern.cputhrottle_cpufreq=1700

second level name cputhrottle_cpufreq in kern.cputhrottle_cpufreq is invalid

bobokimaclaptop:~ root#

the command is actually:

 

sysctl -w kern.cputhrottle_curfreq=1700

 

curfreq not cpufreq

BWHHAHAHA!!!

I cut and pasted what you had typed in your speedstep thread earlier, and I never really even bothered to check spelling.

Thanks for the quick fix roll. Its working now.
