I. Preface

Since I installed CentOS, my video card has never been deprecated. it has been getting too high and the noise is very high. so I decided to search for a solution online. The following is recorded for future reference.

 

II. install fglrx driver (linux driver for ATI/AMD graphics card)

Run the following commands to install

1.

rpm --import http://elrepo.org/RPM-GPG-KEY-elrepo.org

2.

rpm -Uvh http://www.elrepo.org/elrepo-release-6-6.el6.elrepo.noarch.rpmyum -y install yum-plugin-fastestmirror

3.

yum -y install kmod-fglrx

4. restart the system

Now, is the whole world a bit quieter!

 

III. related knowledge

Linux drivers for ATI/AMD graphics cards are divided into radeon (open source) and fglrx (official. We recommend that you use radeon before the HD5000 series and fglrx later. In addition, the fglrx driver can use commands to monitor GPU for overclocking, frequency, and temperature.

The following commands are available after fglrx is installed:

/* View the current GPU frequency and usage */#> aticonfig -- odgc

Note:

1. Current Clocks: Current GPU frequency, which is automatically downgraded in 2D State

2. Current Peak: the default GPU frequency. it is automatically restored to this frequency in the 3D state. overclocking means the default frequency is exceeded!

3. Configuable Peak Range: the configurable frequency Range. the frequency cannot exceed this Range during overclocking, and the frequency reduction cannot be less than this Range. However, since I use HD5730, it is said that it is the super-frequency version of HD5700, so the default frequency has reached the top.

4. GPU load: GPU load, generally 0% in 2D State

 

/* View GPU temperature */#> aticonfig -- odgt

 

/* Overclock */#> aticonfig -- odsc = 500,700

/* Reset frequency */#> aticonfig -- odrd

Note: after restart, the GPU frequency is automatically reset. Therefore, you can use the shell script system to automatically overclock the GPU frequency.

#!bin/bashaticonfig --odsc=500,700exit
