frequency scaling

just wondering, its 2am, and i'm a little bored, so i decided to tweak my conkyrc to show me per core cpu speeds......and I noticed, that the cores on this phenom II X4 aren't scaling indepently, wondering if there's a way to configure that, I'm having a hard time finding anything on the wiki, and elsewhere for that matter

It might be normal. Check the output of cpufreq-info:

$ cpufreq-info | grep same
  CPUs which run at the same hardware frequency: 0 1
  CPUs which run at the same hardware frequency: 0 1

or,
watch grep \"cpu MHz\" /proc/cpuinfo

[urmom@urmom-pc ~]$ cpufreq-info | grep same
  CPUs which run at the same hardware frequency: 0
  CPUs which run at the same hardware frequency: 1
  CPUs which run at the same hardware frequency: 2
  CPUs which run at the same hardware frequency: 3

i'm guessing that means they're scaling indepently?

i'm watching the cpuinfo output right now, seems like they are, since i'm watching them bounce around, cool

cpu MHz         : 3200.000
cpu MHz         : 800.000
cpu MHz         : 800.000
cpu MHz         : 800.000

so maybe i just need to check my conkyrc again, does this look right? the cpu load section works fine, but not the frequency?

${freq cpu1}MHz ${freq cpu2}MHz ${freq cpu3}MHz ${freq cpu4}MHz ${hr 1}$color
CPU Avg :$color $cpu% ${cpubar cpu0 4}
Core1   :$color ${cpu cpu1}% ${cpubar cpu1 4} 
Core2   :$color ${cpu cpu2}% ${cpubar cpu2 4}
Core3   :$color ${cpu cpu3}% ${cpubar cpu3 4}
Core4   :$color ${cpu cpu4}% ${cpubar cpu4 4}

Aren't the CPUs numbered cpu0-cpu3 (not cpu1-cpu4)?

Cpu0 in conky is an average of all CPUs in the system, if i'm not mistaken.
Individual cpu readout starts from cpu1 and so on.
