try using powerthend as a daemon with userspace governor under linux, and in winzoz download the cpu program for dual core daemon from amd site.... powethend gives you the power you need when you need it, and for i have learned it is able to handle both cores....

After I changed their state using gnome applet, and from then on, the two CPUs' bogomips values where equal. For governor set to performance here they are: #cat /proc/cpuinfo |grep -E 'proc|MHz|bogomips' processor : 0 cpu MHz : 1800.000 bogomips : 8125.24 processor : 1 cpu MHz : 1800.000 bogomips : 8125.24 However, if I boot into M$ windblows (dual boot system), then boot into linux without touching the CPUs' freq/gov state the MHz/bogomips values are changed back to: processor : 0 cpu MHz : 800.000 bogomips : 3611.94 processor : 1 cpu MHz : 800.000 bogomips : 1603.39 The 800 MHz is because I have compiled with CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y CONFIG_CPU_FREQ_GOV_USERSPACE=y -- [EMAIL PROTECTED] mailing list
