CPU temperature and clock

[mikekoke]

Hi everyone,
it might seem like a stupid question, but what command should I use to view the current usage of the CPU clock?
One more thing, through the widget and the commands I see the same temperature for all the cores even if I set the temperature sensor on AMD K8 having a fx 6300.
Thanks for your help.

If the sensors widget is showing the same value then that's what the driver is reporting. Either the core s really are all the same or your CPU is not correctly supported by the amdtemp driver.

The CPU usage can be viewed in Diag > System Activity or by running top -aSH at the command line.

Thanks for the help, I thought that something could be done to be able to improve the temperature data, for the first question I mean the clock in real time, how many Ghz are used by each CPU at that time.

It will be running at full speed (or whatever you have set in the BIOS) unless you have enabled powerd in System > Adv > Misc and there is a cpufreq driver that recognises your CPU.
If that is the case it is reported on the dashboard in the System Info widget like:

CPU Type 	Intel(R) Atom(TM) CPU C3558 @ 2.20GHz
Current: 1700 MHz, Max: 2200 MHz
4 CPUs: 1 package(s) x 4 core(s)
AES-NI CPU Crypto: Yes (active) 

You can also see pull those values from the sysctls.

Okay, but is there a command to use in the command prompt to see the clock?

[stephenw10]

[2.5.0-DEVELOPMENT][root@fw321.stevew.lan]/root: sysctl dev.cpu.0.freq
dev.cpu.0.freq: 1162

You can also see the coretemp values there:

Thanks, this is what I meant
