Ubuntu System CPU step-down to extend CPU service life

Summer heat, CPU temperature rose, Desktop is OK, notebook on the trouble. It's a very unsettling affair.
But I've found a solution. Instead of using a heatsink bracket, it is http://www.aliyun.com/zixun/aggregation/7432.html from the source to solve the problem. Not only can reduce the cooling also can prolong the battery use time, even extend the CPU service life.

Meat test Results (early March): The previous cpu100% can reach more than 61 degrees, now live running Mprime can only reach 53 degrees. Mprime never had a passion.
Peacetime use of the temperature now live only about 40 degrees. Before 8630.html "> Sometimes it reaches 50 degrees.
The battery is 1 hours and 20 minutes old and can now live for 1 hours and 35 minutes.

There are two ways to reduce the CPU voltage.

1. Using Cpupowerd (AMD-specific)

Advantages: 1 Direct voltage value adjustment, simple. 2. Do not compile the module
Disadvantage: Only support AMD K8 (Athlon, Athlon64 (X2), Sempron, Opteron, turion ...)
Features: Self-CPU frequency regulator, and cpufrequtils conflict and need to adjust.

Installation
Arch Installation Direct

Code:

Yaourt-s Cpupowerd

Ubuntu here under the source code compilation installation
Http://sourceforge.net/projects/cpupowerd

Code:

Tar-xzf cpupowerd-x.x.x.tar.gz
CD CPUPOWERD-X.X.X/SRC
Make
sudo make install

After installation, check your CPU parameters First

Load MSR Module

Code:

sudo modprobe msr

Load POWERNOW_K8 Module

Code:

sudo modprobe powernow_k8

Code:

$sudo cpupowerd-s
Cpupowerd 0.1.2
