cpupower: No HW Cstate monitors found Jan 27th 2013, 06:48 Hello all, I am running openSuSE 12.2 (x86_64) Code: kde4-config -v Qt: 4.8.1 KDE Development Platform: 4.8.5 (4.8.5) "release 2" kde4-config: 1.0 On a AMD Phenom(tm) II x4 965 Black Edition processor Mounted on a ASUS M4A89GTD-PRO.

Havent used windows in along time but I do remember that I had experimented with turbo boost utilities supplied by the motherboard manufacturer so it could just be that there is no software or drivers in linux that utilizes these capabilities. But C-states should be there. Could it be that powernow-k8 driver is outdated? Or am I missing something here? Any information that would help me to clarify whether is a hardware or software lacking issue would be more than welcome. Thanks in advance.
