Title: powernow and amd cool quiet: does it work?
Post by: hanscees on November 16, 2008, 09:05:11 PM

Hi,
I have searched the forum but didn't find an answer.
Since sme8 and centos won't work with my old via cpu I bought new hardware with and amd 64 LE processor.
However, the cpu-fan is rather busy.

Does sme 7.3 work with cpu-throtling? My cpu does not seem to be throttled. I am trying to get the server to be quiet.

Any info or help would be highly appreciated!

There seems to be info in the kernel source code about what [processors are supported. I tried to download the source with something like this:

yum search --enablerepo=base --enablerepo=updates kernel-source

but that does not work: he says:


Excluding Packages from CentOS - updates
Finished
Excluding Packages from CentOS - os


Is my syntax faulty for using the centos repos??
