First tests with C2D 4400 OC to 2400MHZ worked perfect!
Question: Is it possible that the .kext sets MHZ to highest at kextunload (autotrottle stops but stays at slowest MHZ) time ?
Is it possible that (no priority) you include an temp sysctl value which could be later read out by an gui/menüe tool made by someone else ?
Q2: little off topic, but do you know if the alingement settings in XCODE (G4 / G5 /NONE, mtune= ) does matter or not because PPC and Intel have some differnet alingements ?
1) Sure, good idea. I'll add that.
2) Not sure what you mean by alignment settings: do you mean the optimization setting? It matters for mostly algorithmic or math-heavy apps. Not so much for this kext.
what i realy want now is a good gui app that can display Mhz and Temp.
Are there some other nice app for that around, except coolbook?
You can use tuxx's SpeedStep.app to see the current MHz (set it to manual mode so it doesnt try to autothrottle).
For temp, if you have a dell laptop, you can try I8kfanGUI. Can't say about others. I'll try to add a sysctl key for cpu temp in the next version.
Do you think having speedstep will set much difference on battery time? It is the main reason why I keep searching for this functionality.
PS: I would gladly donate in a few days, if you give me a paypal account to do so. (keep it opensource!)
Some functionality that might be interesting:
- Keeping the CPU at full throttle when plugged to AC (or not as low as the minimum).
1) Yes people are reporting at least 30min extra battery backup with speedstep active. For me the bigger benefit is a cooler CPU.
2) Many thanks. Though I'm not asking for donations yet, some people have expressed interest and I think it's rude to refuse
my paypal address is the same as the email mentioned when loading the kext (sudo dmesg).
3) Keeping CPU on full throttle on AC is a matter of individual preference. The user is able to switch to a frequency of his choice via GUI and turn auto-throttle off via commandline. I'm working on a prefernce pane or menubar applet to make this even easier.
