My Dell T7610 with 2 x E5-2650V2 processors (each with 8 real cores, regular 2.6GHz, turbo 3.4GHz) is stuck at 1.2GHz and I am unable to get it to go faster. How do I get it to go at full speed?
I have followed the advice here to set the governor to "performance": similar question from a year ago. Except I was unable to do the "sudo update-rc.d ondemand disable" command as I got this error:
insserv: warning: current start runlevel(s) (empty) of script"ondemand"
overrides LSB defaults (2 3 4 5).
insserv: warning: current stop runlevel(s) (2 3 4 5) of script"ondemand"
overrides LSB defaults (empty).
And for a while the frequencies did go up, but now they are back at 1.2GHz and do not budge.
Geekbench verifies that this makes a real difference: Geekbench at 1.2GHz and Geekbench at higher freqs. As you can see, I was able to get it to run faster for a while but then it went back to 1.2GHz and the Geekbench load did nothing to change that.
I get this info for each of the 16 processor cores:
analyzing CPU 10:
CPUs which run at the same hardware frequency: 10
CPUs which need to have their frequency coordinated by software: 10
maximum transition latency: Cannot determine or is not supported.
hardware limits: 1.20 GHz - 3.40 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 1.20 GHz and 3.40 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency: 1.20 GHz (asserted by call to hardware)
boost state support:
3100 MHz max turbo 4 active cores
3200 MHz max turbo 3 active cores
3300 MHz max turbo 2 active cores
3400 MHz max turbo 1 active cores
I have tried to adjust the minimum frequency, but the actual frequency stuck way below this minimum:
