CENTOS 6 and AMD A10-6800K Build – Graphics, Overclock and Monitoring

14 Jul

Purpose:  As a builder I wanted to create a CentOS 6 server using a AMD A10-6800K processor, and setup KVM virtualization to host several virtualized OS’s for several purposes.

Build:  Silverstone TJ08B-E, AMD a10-6800K, ASRock FM2A75 PRO4-M, Corsair 32Gb 1600 CMZ32GX3M4X1600C10, Cooler Mater Hyper 212 EVO, Corsair 430W CX430, 2x Seagate Baracuda ST2000DM001, LiteON IHAS124-04 CD/DVD

# Base CentOS install, patching after installing CentOS from the Live CD
yum update

# Elrepro repository for additional packages
rpm -Uvh http://elrepo.org/elrepo-release-6-5.el6.elrepo.noarch.rpm
wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
sudo rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm
vi /etc/yum.repos.d/remi.repo
#  Modify [remi] portion change enabled option to 1

# Radeon Graphics driver required libraries
yum install kernel-devel kernel-sources kernel-headers gcc gcc-c++ libgcc glibc glibc-devel glib2 glib2-devel libstdc++ libstdc++-devel

# Download and install the Radeon Driver
Select install driver and automatic
You will be asked to reboot on completion, accept

#  Testing Graphic driver utilities

# To remove ATI graphics driver

# System monitor gkrellm
yum install gkrellm

# Setup of monitoring tools
yum install lm-sensors
yes “” | sensors-detect
# create a directory to build a kernel module
# download all of the files from https://github.com/groeck/nct6775 to this directory
# you may need to modify the Makefile KERNEL_BUILD paramter to pont to your kernel such as
# KERNEL_BUILD   := /usr/src/kernels/$(TARGET)
make install
# Test module build
modprobe nct6775
#  This should now show your CPU and FAN stats

# Create file /etc/sysconfig/modules/lm-sensors.modules permissions 755
modprobe nct6775 >/dev/null 2>&1
exit 0

# Go into gkrellm configuration / built ins / Sensors
#  your temp, fan, and voltages can be selected based on output from sensors

#  System Stability Tester to load the OS and test stability
gunzip systester-1.4.2-linux-amd64.tar.gz
tar xvf systester-1.4.2-linux-amd64.tar
cd systester-1.4.2-linux-amd64

Conclusion: You can now run systester to load the CPU and monitor CPU temps with the gkrellm GUI to show CPU and Fan temps and speeds.  I have a OC’d system running at 4.6Ghz with a CPU voltage of 1.43, at rest temp 32.5C, load temp 53C
