Subject: How to install cpufreq in CENTOS 5 to disable AMD Cool & Quiet feature?

First, make sure you do this also to turn on cpuspeed for good. Still in SSH, do the following command:

service cpuspeed start

setup

It will display your BIOS.

Go to System Services and check cpuspeed

To know the status of cpuspeed, type this in SSH:

service cpuspeed status

To enable performance governor, do the following steps:

In SSH using root access, do this:

For 64-bit:

yum install cpufreq-utils.x86_64

If yours is not a 64-bit then do a search to know what utils version you should install:

yum search cpufreq

Then run this in ssh:

/usr/bin/cpufreq-set -g performance

If you have more than 1 cpu, then do this command for each cpu. Example in quad core AMD servers:

/usr/bin/cpufreq-set -g performance (this is usually for server 0)

/usr/bin/cpufreq-set -g performance -c 1

/usr/bin/cpufreq-set -g performance -c 2

/usr/bin/cpufreq-set -g performance -c 3

Then do this to turn on performance even after reboot:

nano /etc/sysconfig/cpuspeed

change:

GOVERNOR= # default setting

to:

GOVERNOR=performance

Then in SSH, to check the new cpu clock speed, do this:

cat /proc/cpuinfo
