How do you enable AMD Cool 'n Quiet in the BIOS?

‎12-13-2008 08:45 AM

Hey,

 

I just installed Linux (Ubuntu 8.04) and wanted to enable AMD's Cool 'n Quiet. I've looked around Google and people keep saying to enable it in the BIOS, but every time I go to the BIOS at startup, I don't see anything like "enable Cool 'n Quiet". I do see a "keep fan on at all times" thing, which is enabled, but I didn't want to disable that if it wasn't the right thing. How exactly would I change something like this in the BIOS?

What model computer? On laptops and most OEM computers AMD speedstepping is going to be enabled by default and they are not going to let you turn it off. Ubuntu 8 with the 2.6 kernel will have have the powersave module working so that the processor throttles back and that is all you need, really. Don't sweat it.

 

CPU Frequency Scaling

CPU Frequency Scaling allows you to change the speed at which your processor operates based on certain circumstances. For example if you are in battery mode you can set your processor to power save mode which will scale the CPU down to about 44% of its normal speed in order to conserve energy.

You can enable the CPU scaling monitor by right clicking the panel at the top of the screen and selecting "Add to Panel..." This will bring up a list of applets that you can enable on your panel. Scroll down until you find "CPU Frequency Scaling Monitor." Select it and click the "+Add" button. This will allow you to view the current frequency.

When I try to add the panel, this is the error I get: CPU Frequency Scaling Unsopported You will not be able to modify the frequency of your machine. Your machine may be misconfigured or not have hardware support for CPU frequency scaling. And I've read that the new kernels come with the driver installed, but you have to enable them. I have the applet on my panel and it says it's stuck at 2.10 (100%). This can't be good, since my CPU usage is usually actually around 5% for each core.
