• Amd K10 Specs

I have a HP Pavilion g7 running elementary OS (based on Ubuntu) which is known to be loud and overheat.Mine doesn't shutdown but it does get loud which is very annoying (and 91°C with both Prime95 and Furmark).I searched the internet and found some people under-volt CPUs and get 5 - 20°C lower temperatures.Here's what I tried to install Linux PHC. I downloaded PHC for AMD K8 (my CPU is K10) from here (the top one).Unzipped it and ran sudo make dkmsinstall.Then I added cpufreqdriver=phc-k8 to the boot command line and rebooted. I pressed Esc so I can view the boot messages and I saw a kernel panic although the system booted (most likely the PHC module) without the CPUFreq driver.When it had booted the PHC module was not loaded so that did not work. How can I install PHC on Ubuntu 14.04 with AMD K10 CPU.

Panic Message: 46.670211 kernel BUG at /var/lib/dkms/phc-k8/0.4.6/build/phc-k8.c:667! I think you are likely trying to use the wrong tool for the job.

Amd K10 Specs

There is a project called TurionPowerControl which specifically supports underclocking (and undervolting) AMD K10 processors on linux. The project has been active for a number of years. From their project site: TurionPowerControl, despite its name, allows to view and control many parameters of modern AMD processors. It can manipulate power states, frequencies, DRAM timings, power settings and can report temperatures, monitor pstate changes and precise cpu usage.

It is available for Windows and Linux, for both 32 bit and 64 bit architectures and fully supports multiprocessor machines. Currently supported processors are: Family 10h: All Phenom, Phenom II, Athlon II, Turion Mxxx and Pxxx processors Which covers most of the They state that it compiles fine on recent versions of Ubuntu , and has some very. A basic overview of it's usage / capabilities is in, excerpted here: Change frequency and voltage If you want to change voltage or frequency in a easy manner, you have to use the -set command switch. It is really easy to use and pretty user friendly.

Let's see a simple example. If you want to set the frequency of your pstate 0 to 2000 Mhz to all cores you just have to launch such a command: TurionPowerControl -­set core all pstate 0 frequency 2000 The program will warn you if there isn't a perfect combination that matches the frequency you requested, and will round the result. If you wish to set core voltage too, let's say 1.200 volts, then the command will become like this: TurionPowerControl -­set core all pstate 0 frequency 2000 vcore 1.200 I think this the tool that you need to use to achieve your goal; it actually sounds better suited than what you are currently trying to get working. It is possible that it won't work for you, but based on the information in your question it seems like a solid fit to me.

Link: Update Default pstates for AMD A8-4500M : #1: 1800 MHz, 0.375V #2: 1700 MHz, 0.275V #3: 1600 MHz, 0.225V #4: 1400 MHz, 0.175V #5: 900 MHz, 0.175V In the context of your question, I wouldn't use the same voltage - try a minor decrease to 0.165 or 0.170 to start.
