I've hacked up the ACPICPUThrottle.kext to support full-range CPU throttling on my AMD Turion X2 TK-55 and would love to hear any successes with others wanting AMD throttling. The only thing I can say for myself is that I don't have video support so when I drop to 800MHz it gets very jerky. So if you happen to have a real graphics card and want to give this a go please let me know how it works out for you
Download this: [attachment=34604:ACPICPUT..._Startup.zip]
Move extracted folder to /Library/StartupItems/
Voila, you'll have it going.
If you'd rather test before setting it up as a startup item then just navigate into the folder thats extracted from the zip and run:
sudo chown -R root:wheel ACPICPUThrottle.kext
sudo chmod -R root:wheel ACPICPUThrottle.kext
sudo kextload -v ACPICPUThrottle.kext
dmesg is to check the output to see if everything went alright. If everything did, then run:
sudo ./CPUThrottleCtrl -v
to run the throttling daemon. Let me know how it goes!
I installed ot on my HP dv6640ew (turion tl-58 1.9 ghz) fan runs quietly but I suffer from slow graphic effects (got NVKush) and sound jerks in iTunes ;/ Does anybody know any way to make fan quiet without making graphic slow?
