Yesterday I installed OpenSuse 11.2 on my home PC which has Phenom II X4 925 2.8 CPU but the OS (/proc/cpuinfo and YAST) gives me a CPU frequency of 800МHz.
Is there are a way to fix this ? Maybe next version of kernel ?
It’s probably just because CPU throttling is enabled by default.
If you open the desktop settings tool and on the 2nd tab select power management, you can change it in there to always run at full speed.
But, it’s just wasting electricity for no reason, the throttling is dynamic which means as demand increases, the CPU is sped up to meet it.
It’s from CPU throttling, I wrote a small program that use extensively CPU and cat /proc/cpuinfo | grep MHz gave me :
cpu MHz : 1600.000
cpu MHz : 2800.000
cpu MHz : 2800.000
cpu MHz : 1600.000
Thank you.
