Undervolt the AMD E-350 CPU+GPU with AmdMsrTweaker-Lnx

2015-06-02

Download AmdMsrTweaker-Lnx, extract and compile it.

Load neccessary modules:

sudo modprobe msr
sudo modprobe cpuid

Get some infos:

sudo amdmsrt

Undervolt:

sudo amdmsrt P0=16@1.2 P1=12.8@1.0 P2=8@0.8 NB_P0=0.85 NB_P1=0.8

Where “P0=16@1.2” means:

P-state “0”, multiplicator “16”, voltage “1.2” volts.

PS:

I wrote a daemon for it called amdmsrt-daemon.
