Overclocking and CPU Frequency Scaling

post #1 of 5
Thread Starter 
Anyone had any luck with getting CPU frequency scaling to work in Linux when overclocking? I have overclocked the Phenom in my sig, but Linux will not allow me to have the overclock while also simultaneously using AMD cool 'n quiet. If I turn off C'nQ in the BIOS, Linux recognizes my overclock without a problem. It's only when I have AMD C'nQ enabled that it will scale my overclock down to stock speeds (and wont allow me to scale it up to overclocked speeds).

On Windows this is not a problem, I can overclock and still scale the CPU down to save power. I have read this is because Windows uses a proprietary ACPI and the motherboard makers tend to accommodate Windows while forgetting everyone else.

In any case, anyone had any luck with power saving while still running an overclocked CPU?

It works here, but CnQ with an overclock can lead to BSODs. I've had it lock up (linux) and BSOD in windows so I disabled it. I also run unlocked cores, which can cause CnQ BSODs as well. =(

Nope. Every time I tried to use the applet, it says something like "Because of your set up, you won't be able to use this."

Yeah I've heard people say it works for them too. I dunno what the deal is here. It didn't work with my old X2 Athlon and it doesn't work now.

BTW, I see you got your 545 unlocked. No such luck here. mad.gif

Mine is an original 545 C2 stepping, it was a pain I tell ya. I had to get a bios update with better cpu code before it would work right.

As for the cpu-freq, I build my own kernels and always set it to ondemand for the cpu scaling. I also tend to use grano.la if I enable it, though with the current kernel the default turns it on. I don't have an OC though, as I can't with the unlocked cores. Well I can, but I max at around 3.5, *** is a 500mhz OC worth? I mean, in honest practical application it is useless. It doesn't boot my FPS in games crazy good. =S But yeah, I have default settings for speed. The only thing I have different is the vcore bumped up.
